EDBG also supports a virtual COM port that can be used for device and bootloader programming. One of its most important features is Atmel’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware, significantly increasing the ease-of-use for software debugging. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bitĪRM® Cortex® M0+ core. The Zero applications span from smart IoT devices, wearable technology, high-tech automation, to crazy robotics. The Zero board expands the family by providing increased performance, enabling a variety of project opportunities for devices, and acts as a great educational tool for learning about 32-bit application development. On the STM32duino, DMA is supported and is therefore much faster.The Zero is a simple and powerful 32-bit extension of the platform established by the UNO. I highly recommend a faster microcontroller based on ARM such as the Teensy, STM32duino, Arduino Zero, or the Arduing Due. Not only do you have to write twice as many pixels as a normal 240x320 display, 153,600px (320x480) vs 76,800px (240x320), but you also have to do a lightweight conversion on each color, and write 3 bytes vs 2bytes per pixel.įor this reason, I do not recommend an AVR based Arduino for this library, although it will still work. What this means is, things will be slower than normal.
You can still use the library EXACTLY like you would for 16bit mode color, the colors are converted before sending to the display. I have made some heavy modifications, as the typical Adafruit TFT libraries are designed to work with 16bit color (RGB565), and the ILI9488 can only do 24bit (RGB888) color in 4 wire SPI mode.
It is based heavily on the Adafruit_ILI9341 library and is designed to work with the Adafruit_GFX library. This library is for support for the 320x480 tft controller over 4 wire SPI.
