Arduino digital pins 22-23 doesn't work #1

Open KUSTOMSS opened 9 months ago

KUSTOMSS commented 9 months ago

Hi digital pins 22-53 doesn't work. On arduino in my tune work everything. Any solutions?

pazi88 commented 9 months ago

Are you using the pre-compiled binary?

KUSTOMSS commented 9 months ago

Yes i tried:

I ordered 2 boards with assembly from: https://www.pcbway.com/project/shareproject/STM32_mega_b8a000f3.html

I Found solution. It's not problem with 22-53 digital pins it's problem's with 22-23 digital pins. PC9 - D22 PC8 - D23 This 2 pins is used in code to SD {PC_8, SDIO, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF12_SDIO)}, // SDIO_D0 {PC_9, SDIO, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF12_SDIO)}, // SDIO_D1

Can i disable this pin to SD and it will be work tu aux digital input?? In schematics it doesnt be used to SD

digital pin 46 doesn't work. digital pin 51,53,24 work when sd card is removed.

The pins 22 and 23 don't currently work properly, because those are mapped wrong in the variant file. On purpose though to make serial connection to TS working. The SDIO is not used with speeduino, so it doesn't matter.

I can't think of any reason why pin 46 won't work. Unless you have WMI somehow enabled. It's default pin in there at least in 0.4 board. for the others, I can't think any explanation why those won't work.
