- ILI9486(L) based display
- Touch screen controller XPT2046
In my case STM32 uses FSMC 16bit and SPI via DMA to communicate with the display. There are few things you need to do before the startup:
1.Since the driver uses HAL, make sure you already defined FSMC, SPI and PENIRQ pins in CubeMX.
2.There are functions that you need to define yourown. I'd recommend you doing this inside of spi.c file.
- HAL_SPI_DC_SELECT() - SPI_NSS pin LOW
- HAL_SPI_DC_DESELECT() - SPI_NSS pin HIGH
- HAL_SPI_TxRx() - Transfer and receive data
3.Once PENIRQ pin interrupt happens touchEventHandler() should be called. You need to change pin name and group to ones you've set in CubeMX.
4.If you plan to use built in fonts check header file and uncomment USE_DRIVER_FONTS.
