This is the RFduino Dev Kit, a great duo of products in one box to help you get you started with and teach you the basics of RFduino. Inside this kit you will find two RFduino boards, the DIP mainboard and the USB shield. When attached, these two boards will be able to connect to the USB port on your computer and get your code through the Arduino IDE onto the RFduino DIP board.

The RFduino is a Bluetooth 4.0 Low Energy BLE RF Module with Built-In ARM Cortex-M0 and RFD22301 SMT module for rapid development and prototyping projects. The RFduino operates at 3V and 18mA (4uA ULP), transmits of a 2.4 GHz band, and offers 128kb of flash memory with 8kb of ram. Via a Bluetooth connection with your iOS device you even run a series of free apps to control various shields through the RFduino DIP board. Meanwhile, on-board the RFduino USB Shield is a 3.3V regulator which can be used to supply power to the RFduino DIP module as well as other shields and possibly the rest of your circuit.

With this kit you won"t need to worry about buying the USB shield separately from the RFduino DIP, it"s all in one box and ready to be used right away!

LCD, or Liquid Crystal Displays, are great choices for many applications. They aren’t that power-hungry, they are available in monochrome or full-color models, and they are available in all shapes and sizes.

Waveshare actually has several round LCD modules, I chose the 1.28-inch model as it was readily available on Amazon. You could probably perform the same experiments using a different module, although you may require a different driver.

Open the Arduino folder. Inside you’ll find quite a few folders, one for each display size that Waveshare supports. As I’m using the 1.28-inch model, I selected theLCD_1inch28folder.

Once you do that, you can open your Arduino IDE and then navigate to that folder. Inside the folder, there is a sketch file namedLCD_1inch28.inowhich you will want to open.

Unfortunately, Waveshare doesn’t offer documentation for this, but you can gather quite a bit of information by reading theLCD_Driver.cppfile, where the functions are somewhat documented.

This library is an extension of the Adafruit GFX library, which itself is one of the most popular display libraries around. Because of this, there isextensive documentation for this libraryavailable from Adafruit.  This makes the library an excellent choice for those who want to write their own applications.

The TFT_eSPI library is ideal for this, and several other, displays. You can install it through your Arduino IDE Library Manager, just search for “TFT_eSPI”.

There is a lot of demo code included with the library. Some of it is intended for other display sizes, but there are a few that you can use with your circular display.

To test out the display, you can use theColour_Test sketch, found inside the Test and Diagnostic menu item inside the library samples.  While this sketch was not made for this display, it is a good way to confirm that you have everything hooked up and configured properly.

In order to run this sketch, you’ll need to install another library. Install theTjpeg_DecoderLibrary from Library Manager. Once you do, the sketch will compile, and you can upload it to your ESP32.

The Animated Eyes sketch can be found within the sample files for the TFT_eSPI library, under the “generic” folder.  Assuming that you have wired up the second GC9A01 display, you’ll want to use theAnimated_Eyes_2sketch.

The GC9A01 LCD module is a 1.28-inch round display that is useful for instrumentation and other similar projects. Today we will learn how to use this display with an Arduino Uno and an ESP32.

I"m writing ann application in Swift that requires I be able to send and receive data from an iOS device to an RFDuino. Building on top of cconway"s UBP library, I"ve been able to get my RFDuino"s temperature measurements to display on my iPad, but now I"m working on getting the iPad to send a simple message to the RFduino.

The following instructions are specific to the 2.4″ LCD Shield sold by ZYLtech Engineering. These instructions may or may not work for non-ZYLtech LCD shields. The LCD shield works with Arduino UNO/Mega (ATMEGA16U2 or CH340 version). It may also work with other boards as well.

Please note: The instruction is for ZYLtech Arduino 2.4 LCD Shields purchased after May 23, 2016. Information for the older version can be found in the second part of this instruction

Next, download the modified sketch for TFTpaint, from which you will learn how to use the touchscreen function of this LCD shield. In order for this sketch to work properly, you will need the following two libraries. (Download, unzip and copy to your Arduino IDE library folder.)

​If your x, y coordinates of the Touch Screen are inverted, try comment/uncomment line 51/53 in the TFFTLCD.CPP file. If you get a white screen it is probably because there is already a TFTLCD.cpp file in your library. Find the following code in your TFTLCD.CPP file and add delay as showing below:

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.
