pololu 32u4 tft display made in china
What ends up happening is the LCD’s have gone from displaying actual text, to now only showing rows of blocks across the screen. And the motor/wheel test function that the robots seem to have had programmed into them no longer work (I do not know if they were prepackaged this way or if someone working on this before me had programmed them with that function).
That TFT LCD display from Adafruit uses SPI to communicate. You should be able to use the SPI pins on the ISP header on the A-Star to communicate with that display. You might find the diagram below helpful for using those pins (we will try to add this to the user’s guide soon).
This diagram identifies the I/O and power pins on the A-Star 32U4 Mini (ULV, LV, and SV versions); it is also available as a printable PDF (223k pdf). For more information about the ATmega32U4 microcontroller and its peripherals, see Atmel’s ATmega32U4 documentation.
The yellow LED is connected to Arduino pin 13, or PC7. You can drive this pin high in a user program to turn this LED on. The A-Star 32U4 Bootloader fades this LED on and off while it is waiting for a sketch to be loaded.
The green LED is connected to the pin labeled TXL, or PD5, and lights when the pin is driven low. While the board is running the A-Star 32U4 Bootloader or a program compiled in the Arduino environment, it will flash this LED when it is transmitting data via the USB connection.
The red LED is connected to the pin labeled RXL (usable as Arduino pin 17), or PB0, and lights when the pin is driven low. While the board is running the A-Star 32U4 Bootloader or a program compiled in the Arduino environment, it will flash this LED when it is receiving data via the USB connection.
The A-Star 32U4 includes a USB Micro-B connector that can be used to connect to a computer’s USB port via a USB A to Micro-B cable (not included). The USB connection can be used to transmit and receive data from the computer, and a preloaded USB bootloader makes it possible to program the board over USB. The USB connection can also provide power to the A-Star.
The A-Star 32U4 Mini can either be powered directly from the USB 5 V supply or from an external voltage source, which is regulated to 5 V by its onboard switching regulator.
In some situations, it might be undesirable for the A-Star 32U4 Mini to draw power from an external source when it is connected to USB. If this is the case, the regulator can be disabled by driving the regulator shutdown pin, SHDN, high; this shuts down the regulator and causes the power mux to fall back to USB power. For example, this could allow a battery-powered device to turn off the regulator and avoid draining its battery while it is connected to a computer.
3V3 power output: This pin gives access to the output of the internal 3.3 V regulator inside the ATmega32U4. The microcontroller uses this regulated voltage for USB signaling, but up to about 50 mA is available for powering external circuits or devices.
When the A-Star 32U4 Mini is being powered through VIN, the sum of the 5V output current, 3V3 output current, GPIO output current, and current used by the board itself should not exceed the maximum current that the regulator can provide; see the following sections for details about the regulator on each version.
The Pololu A-Star 32U4 Prime is a general-purpose programmable board based on Atmel’s ATmega32U4 AVR microcontroller and arranged in the common Arduino form factor exemplified by the Uno R3 and Leonardo. As such, the A-Star Prime (abbreviated A* Prime) is compatible with many Arduino shields, including all of the Arduino shields we carry. All 26 of the microcontroller’s GPIO lines are accessible on the board, including seven than can be used as PWM outputs and twelve that can be used as analog inputs. The ATmega32U4 is capable of native full-speed USB, which makes it more versatile than similar boards that rely on USB-to-serial adapters: in addition to supporting a virtual (CDC) serial/COM port interface, the A-Star can appear to a connected computer as a mouse and keyboard. The A-Star’s USB interface can be accessed through its USB Micro-B connector.
FeaturesProgrammable ATmega32U4 MCU with 32 KB flash, 2.5 KB SRAM, 1 KB EEPROM, and native full-speed USB (clocked by precision 16 MHz crystal oscillator)
All 26 general-purpose I/O lines from the ATmega32U4 are broken out (including PB0, PD5, and PE2); 7 of these can be used as hardware PWM outputs and 12 of these can be used as analog inputs

This is a library for the Adafruit RGB 16x2 LCD Shield Pick one up at the Adafruit shop! ---------> http://http://www.adafruit.com/products/714 This new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the range of LCDs we stock in the shop, such as our classic blue & white as well as the fancy RGB negative and RGB positive. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then perhaps another 3 to control the RGB backlight for a total of 9 pins. That"s half of the pins available on a classic Arduino! With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino! The best part is you don"t really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle.

Display a value on a single LED Since I can"t use Exceptions, I have provided some defaults if input parameters are negative, see DisplayValueOnLed.cpp for exact values.
LED Bar, common in volume display, is a common sensor component to display analog value. You can use a row of discrete LED lights to make division of this effect, you can also use our element mentioned here. For more information, please refer to http://www.seeedstudio.com/wiki/LED_Bar
4 digit display module is usually a 12 pin module. In this Grove gadget, we utilize a TM1637 to scale down the controlling pins into 2 Grove pins. It only takes 2 digital pins of Arduino or Seeeduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice
This library supports Graphical LCD (GLCD) displays for use with Arduino and other AVR controllers This library is the updated version of the arduino ks0108 library by Michael Margolis. Michael has teamed up with Bill Perry to produce a new version of the library with many new features. Highlights include support for additional glcd chips, support for all Arduino print methods, user definable scrolling text areas, as well as a new method of configuring i/o pins that is much simpler and allows any AVR pin to be assigned to any glcd hardware pin.
Arduino library that allows you to create a tiny 20x16 pixel bitmap (raster) display on a normally character-only Hitachi HD44780 based LCD display. Typical drawing functions like line, rectangle, invert, etc. Control is right down to the pixel level. More info inhttps://code.google.com/p/arduino-lcd-bitmap/
This library is designed to make communication with an APA102 LED strip simple and compact. It provides an object with just a few interaction methods to write individual pixels or all pixels at once, clear and draw functions to update the display, and a single number color interface to simplify color mixing.
LcdBarGraph is an Arduino library for displaying analog values in LCD display, which is previously initialized. This library uses LiquedCrystal library for displaying.
http://playground.arduino.cc/Main/LedControl -- There is already a library and a lot of code-examples for the Arduino and the MAX72XX available, but the focus had always been on controlling Leds layed out in some sort of rectangular matrix. I use the MAX72XX to drive 7-segment displays, so I wanted a function to display numbers (decimal and hexa-decimal) and also the limited set of alphanumeric characters that make (visual) sense on this kind of displays. But the library also provides a basic set of functions by which either individual or groups of Leds can be switched on and off.
LedDisplay lets you use a Avago HCMS-29xx type display. These are small, very bright and easily readable 4 or 8 character displays. They are also quite expensive.
http://www.pjrc.com/teensy/td_libs_LiquidCrystal.html -- LiquidCrystalFast can use the R/W pin for faster access. Either way can update the display faster than a human eye can detect, but if your project needs to do other work, less time updating the display may be worth using a seventh pin.
An Open Source library to easily control multiple 32x8 LED matrix display boards with simple printf like functions. http://embeddedsoftdev.blogspot.ca/p/arduino.html
The Matrix library from Wiring. The Matrix library allows for writing data to a external LED matrix display using the MAX7219 LED matrix controller. More info in http://wiring.org.co/reference/libraries/Matrix/
These are super cheap 4 digit displays, with no decimal points, and the words "CLEAR" and/or "SECURE". They must have been made for a security alarm. These are not smart, and must be continually refreshed (supplied software driver does this). They can be purchased as surplus for as little as $1.95. This software requires the use of library MsTimer2.
http://www.pololu.com/docs/0J17/5.a -- This library provides a set of methods that can be used to read analog voltage inputs, as well as functions specifically designed to read the value of the trimmer potentiometer (on the 3pi robot, Orangutan SV-xx8, Orangutan LV-168, and Baby Orangutan B), the battery voltage level in millivolts (3pi robot, SV-xx8), and the value of the temperature sensor in tenths of a degree F or C (on the Orangutan LV-168 only). This library gives you more control than existing Arduino analog input functions. You do not need to initialize your OrangutanAnalog object before use. All initialization is performed automatically when needed. All of the methods in this class are static; you should never have more than one instance of an OrangutanAnalog object in your sketch.
http://www.pololu.com/docs/0J17/5.b -- This library allows you to easily control the piezo buzzer on the 3pi robot, Orangutan SV-xx8, and Orangutan LV-168. It gives you the option of playing either a note or a frequency for a specified duration at a specified volume, or you can use the play() method to play an entire melody in the background. Buzzer control is achieved using one of the Timer1 PWM outputs, and duration timing is performed using a Timer1 overflow interrupt, so this library will conflict with any other libraries that rely on or reconfigure Timer1. For example, the Arduino function analogWrite() will not work on the Timer1 PWM output pins once you have started to use this library in your sketch. The benefit to this approach is that you can play notes on the buzzer while leaving the CPU mostly free to execute the rest of your code. This means you can have a melody playing in the background while your Orangutan or 3pi does its main task. You can poll the isPlaying() method to determine when the buzzer is finished playing. You do not need to initialize your OrangutanBuzzer object before use. All initialization is performed automatically when needed. All of the methods in this class are static; you should never have more than one instance of an OrangutanBuzzer object in your sketch.
http://www.pololu.com/docs/0J17/5.c -- This library gives you the ability to control the 8×2 character LCD on the 3pi robot, Orangutan SV-xx8, and Orangutan LV-168. It implements the standard 4-bit HD44780 protocol, and it uses the busy-wait-flag feature to avoid the unnecessarily long delays present in other 4-bit LCD Arduino libraries. This comprehensive library is meant to offer as much LCD control as possible, so it most likely gives you more methods than you need. You can comment out unneeded methods (e.g. showCursor()) in OrangutanLCD.cpp to make this library smaller. If you do this, remember to delete OrangutanLCD.o so and restart the Arduino IDE so that the library will be recompiled. This library is designed to gracefully handle alternate use of the four LCD data lines. It will change their data direction registers and output states only when needed for an LCD command, after which it will immediately restore the registers to their previous states. This allows the LCD data lines to function as pushbutton inputs and an LED driver on the Orangutan and 3pi. You do not need to initialize your OrangutanLCD object before use. All initialization is performed automatically when needed. All of the methods in this class are static; you should never have more than one instance of an OrangutanLCD object in your sketch.
http://www.pololu.com/docs/0J17/5.d -- This library allows you to easily control the LED(s) on the 3pi robot, Orangutan SV-xx8, Orangutan LV-168, and Baby Orangutan B. On the Orangutan SV-xx8 and LV-168, there are two user LEDs are on the top side of the PCB with the red LED on the bottom left and the green LED on the top right. On the 3pi, there are two user LEDs on the bottom side of the PCB with the red LED on the right (when looking at the bottom) and the green LED on the left. Additional LEDs included with the 3pi may be soldered in on the top side (in parallel with the surface-mount LEDs on the underside) for easier viewing. The Baby Orangutan has a single red LED and no green LED. Note that the red LED is on the same pin as the UART0 serial transmitter (PD1), so if you are using UART0 for serial transmission then the red LED commands will not work, and you will see the red LED blink briefly whenever data is transmitted on UART0. Note that the green LED is on the same pin as an LCD control pin; the green LED will blink briefly whenever data is sent to the LCD, but the two functions will otherwise not interfere with each other. You do not need to initialize your OrangutanLEDs object before use. All initialization is performed automatically when needed. All of the methods in this class are static; you should never have more than one instance of an OrangutanLEDs object in your sketch.
http://www.pololu.com/docs/0J17/5.e -- This library gives you the ability to control the motor drivers on the 3pi robot, Orangutan SV-xx8, Orangutan LV-168, and Baby Orangutan B. It accomplishes this by using the four hardware PWM outputs from timers Timer0 and Timer2, so this library will conflict with any other libraries that rely on or reconfigure Timer0 or Timer2.
http://www.pololu.com/docs/0J17/5.f -- This library allows you to easily interface with the three user pushbuttons on the 3pi robot, Orangutan SV-xx8, and Orangutan LV-168 by either polling for the state of specific buttons or by waiting for press/release events on specifiable buttons. The waitFor____() methods in this library automatically take care of button debouncing. You do not need to initialize your OrangutanPushbuttons object before use. All initialization is performed automatically when needed. All of the methods in this class are static; you should never have more than one instance of an OrangutanPushbuttons object in your sketch.
http://www.pololu.com/docs/0J17/5.g -- This library allows you to easily interface with the five infrared reflectance sensors on the 3pi robot. Note that in order to use this library, you must also include PololuQTRSensors.h in your sketch. You should have something like the following at the top of your sketch: ? 1 2 3 4 #include
The Pushbutton library provides a set of functions that are useful for detecting and debouncing pushbutton presses. While the most obvious application of this library is to work with the Zumo Shield�s user pushbutton on digital pin 12, this library can be used as a general-purpose library for interfacing many types of buttons and switches to an Arduino, even without a Zumo Shield. This library comes with an example sketch demonstrating its use. More info in https://github.com/pololu/zumo-shield
This library, which can also be found in the qtr-sensors-arduino repository, is a general library for interfacing with Pololu QTR reflectance sensors. Since the Zumo Reflectance Sensor Array has the same interface as the QTR RC reflectance sensors, the ZumoReflectanceSensorArray library uses QTRSensors to read the sensor array. More info in https://github.com/pololu/zumo-shield

This is my attempt at porting LiquidCrystal library for use with serial displays. It implements most all functions from LiquidCrystal and added a few functions of my own. This library subclasses NewSoftSerial. More info in http://playground.arduino.cc/Code/SerLCD and https://github.com/nemith/serLCD
TM1636 is a TickTock which contains all funtions to control four 7-segment displays. http://www.seeedstudio.com/wiki/Tick_Tock_Shield_Kit#TM1636_class
This library is an add-on to UTFT and will not work on its own. This add-on library also requires the tinyFAT library. This library adds a simple way to load images from SD cards. The images must be in the .raw format. Images can be converted to the .raw format with the ImageConverter565 supplied with the UTFT library or the online version found on my website.
This library is primarily an add-on to UTFT, but the library in it self does not require UTFT. The supplied examples DO however require the UTFT library. The library works great with the ITDB02 Arduino MEGA Shield v2.0 from ITead Studio and the TFT01 Arduino Mega Shield from ElecFreaks.
The ZumoBuzzer library provides functions that allow various sounds to be played on the buzzer of the Zumo Shield, from simple beeps to complex tunes. This library is fully compatible with the OrangutanBuzzer functions in the Pololu AVR C/C++ Library, so any melodies written for OrangutanBuzzer functions will also work with ZumoBuzzer functions. This library comes with some example sketches demonstrating its use. More info in https://github.com/pololu/zumo-shield
The ZumoMotors library provides functions for PWM-based speed (and direction) control of the two motors on the Zumo with the onboard DRV8835 dual motor driver. On Arduinos with ATmega328P, ATmega168, and ATmega32U4 microcontrollers (which include the Leonardo, Uno, and most older Arduinos), the motor control functions use hardware PWM outputs from Timer1 to generate pulse width modulation at a 20 kHz frequency. If you accidentally soldered a motor to the Zumo Shield backwards (opposite the orientation indicated in the assembly instructions), you can simply call flipLeftMotor(true) and/or flipRightMotor(true) to make the motors behave consistently with the directions in your code. This library comes with an example sketch demonstrating its use. More info in https://github.com/pololu/zumo-shield
This library provides a set of functions for reading reflectance values from a Zumo Reflectance Sensor Array. This library depends on the QTRSensors library. The ZumoReflectanceSensorArray class is a subclass of QTRSensorsRC. The functions provided by QTRSensorsRC can also be used on the ZumoReflectanceSensorArray class, and are documented in the Arduino Library for the Pololu QTR Reflectance Sensors document on Pololu’s website. This library comes with an example sketch demonstrating its use. More info in https://github.com/pololu/zumo-shield
