Hi,I am trying to create a reliable communication in a noisy environment using RS-485 between 2 STM32 boards, one with STM32F302 that is receiving data from several sensors, performs some calculations and then send the data to a STM32H723 Board. On b...

Hello all,I have an STM32F722RETx that is receiving data on UART from an ESP8266. This data is variable in length and I use DMA + IDLE interrupt to know when to process it. When debugging the code I can only see the first byte in the buffer as no oth...

I have bought a logic analyzer from SparFun and tried to debug the fact that I am not receiving the proper data in my UART buffer.At the input of ST485E I am getting the proper array of bytes but on the RO pin (connected to UART8 Rx) I am missing on...

Hi, I came up with the code below#include "stm32f7xx_hal.h" // Global variables TIM_HandleTypeDef htim2; uint32_t time_interval = 0; // TIM2 Initialization Function void TIM2_Init(void) { TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_IC_In...

Thank you for your reply Jan.I have looked in to RM0431 chapter 19.3.6 and unfortunately i am not able to figure this out.Is it possible to provide me the configuration code for TIM2?I know I am asking too much, but this set up is above my skills.
