Doubt with GPIO config in stm32cubemx

[rubenles]

Hello,

I have a question while configuring the GPIO on stm32cubeMX. I put all my pins in the program like this:

When I configure all the pins and generate the code, not all the configured pins appear in the gpio.c file on stm32cubeIDE; for example, the UART RX and TX pins do not appear in stm32cubeIDE.

Thank you so much.

Hello,

Could you please share your ioc file reproducing the behavior as we could understand what is going on?

Because they are used as UART RX & TX - rather than just as GPIOs ?

Have you looked in the UART config?

EDIT:

See the HAL_UART_MspInit() in your usart.c; also look in main.h ...

Normally, pins are initialized in stm32h7xx_hal_msp.c for most peripherals.

@Andrew Neil UART config was there, true, thank you so much for this advice!!! Other gpio still doesn't appear, but uart is solved thank you!!

@TDK This file is empty for me, just one interrupt configuration is in there

  __HAL_RCC_SYSCFG_CLK_ENABLE();

  /* System interrupt init*/
  /* PendSV_IRQn interrupt configuration */
  HAL_NVIC_SetPriority(PendSV_IRQn, 15, 0);

But nothing about gpio configs.

Thank you

Just trying to generate the code to show it to you, i realize that now all the gpio configs are there. I don't really know if i was confused just with UART or it was an error. By the way, it is solved, thank you so much.
