ILI9341 driver for ElectroSmith Daisy Seed platform

Overview

• In current state, it is capable producing solid 40 FPS.
• Uses DMA for SPI communication.
• Uses DMA2D for faster writing to a buffer.

Usage

The driver expects specific pin configuration. You can change the pins in the ILI9341SpiTransport::Init() function.

Below is the default configuration:

D7 (SPI1_CS)    -> ILI_CS
D8 (SPI1_SCK)   -> ILI_SCK
D10 (SPI1_MOSI) -> ILI_MOSI
D17             -> ILI_DC
D23             -> ILI_RESET

  spi_config.pin_config.nss  = {DSY_GPIOG, 10}; // D7
  spi_config.pin_config.sclk = {DSY_GPIOG, 11}; // D8
  spi_config.pin_config.mosi = {DSY_GPIOB, 5};  // D10

  auto dc_pin    = seed::D17;
  auto reset_pin = seed::D23;

Then, follow main.cpp to draw stuff on the screen.
