I try a lot of clock configurations but it always response command timeout error at the following line of the generated MX_SDMMC1_SD_Init function.if (HAL_SD_Init(&hsd1) != HAL_OK) { Error_Handler(); }How should I set the SDMMC1 configuration for ST...
Hello! I having some problems using USART and timersI'm receiving data by USART1+DMA and sending it by USB every 100[ms], if no data is received in 1[s], then timer TIM2 make an interrupt and sends a special USB message. This is done resetting timer'...
Hello! Can you help me?I'm receiving data in UART Rx with DMA and send it by USB, it works fine. Now i'm trying to set up a timer to check if I'm receiving data every 250[ms] and send a special message. When I don't configure the timer it works, but ...

Hello eveyone,In my code i try to set the BOR level with the following function:/** * Set proper BOR level. */ void setBorLevel(void) { FLASH_OBProgramInitTypeDef optionBytesInit = {0U}; bool_t isBorLevelConfigured; uint32_t borLevel = ...
Hello!I'm working on a custom board with an stm32L051 and the HSI16 crystal. I'm setting the clock registers, Flash, PWR and then I try to enable the clock for TIM21. as you can see in the code I set the bit but the computer "doesn't listen"(I am loo...
I want to perform a timer interrupt using the output comparison mode.When the frequency is set to 2000Hz, ARR : 20, CCR1 : 25, I think that interrupt does not occur because ARR <CCR1, but interrupt occurs. Why do interrupts occur?
Hello,I need some examples to learn how to configure and use the touchscreen on STM32H747I-DISCO board.Could you provide it or direct me to the resources which contain such an example, please.Thanks,Best regards
