![]() To print characters to a graphic screen we need a font. To use the SD card simply import the SDFileSystem and connect it to the second SPI. The board can be used without modification. The board has also a SD card connector at the backside, but no touch. There are inexpensive displays from china. media/uploads/dreschpe/mi0283qt_v12_patch.pdf Display 3 Watterott will change this in a future revision. Mosfet Q1 can be driven with a logic signal without converter. You can use the level converter used for the LCD_LED signal. You also have to get access to pin 36 for the dc signal. If you want to patch this - like I have done - you have to desolder the TFT from the pcb to cut some traces. Unfortunately this adapter is set to 9 bit SPI mode via the mode pins IM0-IM3. ![]() Watterott is also selling a ILI9341 based QVGA TFT : You can use two 10R resistors parallel to get 5R driven by 3.3V. ![]() The backlite LED need a resistor to limit the current. If you use the TFT Proto from MikroElektronika _NUCLEO.cpp, port and send me the code to add. The #ifdef definition around is switching between the platforms. ![]() To prevent unreadable code with a lot of #ifdef. To do this I have to split the code for the different platforms. I have started to speed up the lib with using DMA and direct SPI programming. The IM pins have to be set to 1110 (IM3-IM0) to use this mode. The lib is using the 4 line serial data interface. The lib is based on the code for the older LCD board. Lib for 320*240 Pixel Color LCD with ILI9341 controller. ![]()
