Bluepill STM32F103C8T6 and ST7789 only works by removing "#define STM32" #3093

HI there, I'm facing a problem with "bluepill (STM32F103C8T6)" to run "240x240 ST7789" Display. As recommended I used "Setup32_ILI9341_STM32F103" and modified this by removing

#define ILI9341_DRIVER

and adding

#define ST7789_DRIVER
#define TFT_RGB_ORDER TFT_BGR   //Because the Color wasn't right

But for two days I can't seems to get it work. I tried using the recommended connection and also by using other PINs for CS, DC, RST Today I found out that if Comment out

//#define STM32

only then it works.

I'm not sure if it's a problem from the library or the problem is somewhere else. I'd appreciate it if you kindly look into this matter. Thank you.

This is due to breaking updates to the STM32 board package. This has been fixed as noted in #3046.

Your options are:

  1. Commented out the #define STM32, but this will have a screen update performance impact.
  2. Downgrade the board package to 2.6.0
  3. Upgrade TFT_eSPI from the Github master and then use board package 2.7.1

In the longer term, option 3 is probably the better option.

Thank you very much for your reply. I went with the option 3 and the display worked and it's blazing fast. But unfortunately after doing that "SD_Jpg" example from your "TJpg_Decoder" library didn't worked as expected. It was fine before, but now the color seems yollowish and screen tearing occurs and sometime the image can't be displayed in its entirety. "Flash_Jpg" works fine. Another thing is that "Flash_Jpg_DMA" doesn't work, so I tried DMA test "boing_ball" the background was there but the ball never showed up.

I'm using same SPI port for SD and TFT

OK, looks like the new board package broke the DMA too.

The problem with jpegs might be down to the increased performance. I will investigate further.

In the meantime downgrade the board package to 2.6.0, the latest TFT_eSPI should still work with that board package.

Bodmer commented 9 months ago

I think the incorrect colours for the jpeg should be fixed now, the master library has been updated.

DMA for SPI is still not working for board packages above 2.6.0
