Hello,
I have a NUCLEO-H755 + NUCLEO GFX02Z1.
NUCLEO GFX02Z1 is based on DT022CTFT screen (ILI9341 drivers) and MX25L6433FM2I QuadSPI memory.
With ST Software package X-CUBE-DISPLAY 3.0.0, I have severals problems :
- With GFX02 "HelloWorld" example, there is nothing in MX_DISPLAY_Process(); function ??
- With LCD configuration (ILI9341 drivers) configured on FMC, it's working fine because the MX_DISPLAY_Init() successful passed (ReadID OK).
- With memroy configuration, there is no QuadSPI configuration, only SPI. QuadSPI is only available with "custum" selection. So, if i select Custom + QuadSPI (and not MX25L6433 + SPI) I will loose MX25L6433 drivers produce with X-CUBE-DISPLAY soft ...
But at this moment, I just want to print a character or backgrtoung color but the screen remains white ...
My understanding :
To not configure QuadSPI memory is not a problem at this moment because I don't use DMA transfer (no DMA), so no transfer from peripheral to Memory and/or Memory to Peripheral.
So after MX_DISPLAY_Init(); sucessfull, i try to use BSP_LCD_WriteData() function.
But nothing happenend on the screen ... I try after a BSP_LCD_DisplayOn(0); but same ...
Is there something missing ?
Thanks in advance for your answers,
Regards,
