Hello,
I am using a custom board with the STM32L452RET. On this board:
- SPI1 is connected to an IIS3DWB accelerometer,
- SPI2 is connected to a 240x280 TFT display with an ST7789 controller and TouchGFX,
- SPI3 is used with FatFs to access an SD card, following this tutorial: https://controllerstech.com/sd-card-using-spi-in-stm32/,
- USB CDC is used for communication.
After adding FatFs, the wildcards with float values that should be displayed on the screen only show characters from 5 to 9. Characters from 0 to 4 appear as black blocks. I modified the text settings in TouchGFX in various ways. The only configuration that showed some results was changing the BPP in the typography from 4 to 8.
The images show the result with and without FatFs running.
I appreciate any help.
