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 ...
i tried to use the internal temperatur sensor but its a little bit strangewhen the tempertur goes up the value from the adc goes downis that right or is my config for the adc wrong ?
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
I'm using STM32CubeMX and HAL functions.I've gotten interrupt capture working for Timer 3 Channel 3. However, my input frequency is low and the 16-bit capture value is overflowing multiple times. I've solved this many times in the past with a diffe...
I'm reading data from an FPGA over QSPI. I'm attempting to read 256 bytes at a time. However, when I read the data the QSPI clock decides to take a long pause before continuing. I get an initial burst of 74 clock pulses, then 56 bursts of 8 clock pul...
