rfduino lcd panel library pricelist

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (7" diagonal) bright (14 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (Due/Mega 2560). This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

However, three major evolutions have taken place since the initial Serial_LCD release back in May 10, 2011: widely available and cheaper screens, more powerful MCUs, popular libraries.

I have tested the screen with a sketch and is working fine, just show me this kind of erros when trying to include the GFX and SSD1306 library together with RFduino library.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

You can find the previous article here. It contains a description of the LCD module, shows you how to connect the display to your Arduino UNO board and describes the basic rules of operating it using the software. Still, it needs to be admitted here that there is only a limited number of applications for an LCD alone, because in the case of such a simple LCD module no settings can be entered. To do so, you need a keyboard, which we will discuss in detail in one of the future articles, but now let us use a ready-made solution from the Arduino ecosystem – a board from Olimex – SHIELDLCD16x2.

This is a shield board which extends Arduino capabilities, equipped with an LCD module (2 lines of 16 characters each), 4 buttons and 8 additional GPIO lines. On the board, there is a PIC processor which communicates with Arduino UNO via the TWI interface. With access to a library of functions, operating this module with a built-in microcontroller should not cause any major problems. Let"s start with preparing the module for operation.

There are two steps to prepare the module for work: hardware and software. The first one is simply to plug the shield into the Arduino UNO board. The second one requires you to install a library of module operating functions.

To install the library, go to the module manufacturer"s website i.e. Olimex. Then, in the search box (next to the Search button) enter the part of the module name "LCD16x2". (Figure 1). Click on the Search button. When this text was being created, the search retuned two results – please, select "SHIELD-LCD16x2".

Under the description of the module, you can find the "SOFTWARE" section (figure 2). Each line of text in this section is also a link to a file that can be downloaded from the Olimex website. At this point, we are looking for the link saying: "OLIMEXINO-328 + SHIELD-LCD16x2 – a library and set of demo examples".

Download the ZIP file available at this link to your computer. Of course, it is worth having a look at the available examples, but for our needs it is enough to install the library saved in the LCD16x2 catalogue.

The Arduino IDE allows for various different ways of installing libraries. In this case, the easiest way is to upload the sources to the project directory, which also contains a libraries subdirectory. The project directory is created during the installation of Arduino IDE, and Windows usually places it (in the Polish language version) in subdirectory Ten Komputer → Dokumenty → Arduino. To add the library sources to today"s example, just move the LCD16x2 directory to the libraries folder. Once you"ve done that, launch the Arduino IDE.

Before getting started with your own program, you should read examples of using the LCD16x2.h library of functions available in the Examples directory. It is a much more effective method of learning than reading documentation, although it is worth remembering about the latter as well.

As mentioned before, the shield communicates with the UNO board using a serial interface. It"s easy to guess that the functions described in the previous article must be modified, because they used a parallel, 4-bit interface. As you can imagine, the microcontroller on the shield board communicates with the LCD character display module in the same way, but our Arduino UNO cannot "see" the display, and the control is done indirectly. Therefore, start the program by adding libraries to support the appropriate serial interface and the display module mounted on the shield board.

To make it simple, in order not to use the long library name, it is recommended to assign to it the lcd alias. We will use it by writing the name of the library function after the dot.

The initialization function starts the TWI interface, clears the LCD screen, and turns on the display backlight at the maximum LED light intensity (0 parameter turns off the backlight).

Mask 0x01 corresponds to the first button on the left, while 0x08 corresponds to the first button on the right. The program numbers the buttons by giving the pressed variable a value corresponding to the conventional button number. Then, this number is shown on the LCD screen, at the position starting in the first row and the first column. The message is displayed only if the pressed value is different from 0. Otherwise, the message "No button" is displayed, indicating that no button is pressed. The message is terminated with three spaces so that when overlaid on "1 is pressed" (which is longer) the last characters of the caption are cleared.

The library allows to control I2C displays with functions extremely similar to LiquidCrystal library. THIS LIBRARY MIGHT NOT BE COMPATIBLE WITH EXISTING SKETCHES.
