Hello!I'm using a 320x240 TFT display with ST7789V driver and SPI interface by X-CUBE-DISPLAY. Pixel transfer works correctly when I use the BSP_LCD_WriteData function. I can also display images and animation using the TouchGFX framework.However, whe...

Hi Community,Is it possible to cache all fonts at the startup of TouchGFX in order to have a single memory access?The documentation provides an example of caching a single font associated with a text box when a screen starts. If I understand correct...

I'm working on a custom STM32U5 board with TouchGFX. The board features an external NOR flash memory used for storing the ExtFlashSection (as documented here).In my project testing, I aim to display a simple black and white image with a transparent a...

I am currently developing on a custom board based on the STM32U5 microcontroller with the MX25UM512 NOR flash memory. I am following the example provided by the STM32CubeU5 SDK. The example works correctly when I first run it (so data is written corr...

I'm developing a custom board with an STM32U5 MCU and a MX25UM51245 NOR flash memory. I'm building upon this example, which works flawlessly, but I don't want to format the memory every time the code runs. To achieve this, I disabled the Driver calls...

Update:It seems that the BSP_LCD_WaitForTransferToBeDone() function does not wait for the entire byte transmission to complete.Therefore, it was necessary to replace it with the following line of code to make it work. while (hspi2.State != HAL_SPI_ST...

Hi @Bicer @Gde S.3 , this post might be a bit older, but I think it could still be helpful for others.Have you verified that the SPI transfer rate is the maximum supported by the driver (15 MHz)? Using DMA will not significantly improve performance ...

Hi @LouisB ,Thanks for your support. Could you please provide an example of how to do what you described? I'm not sure which APIs I should use to cache all the fonts. Regards,

Hi @MM..1 ,So, you're saying that the fact that blockCopy is called even when I'm not using the cache is a behavior not foreseen by the documentation? This would explain the strange behavior in my setup...If I don't want to use the cache, do I have t...
