HRTIM periodic calibration

I use HSI16 as my clock base which goes through a PLL and then into the HRTIM.Let's say that I adjust HSI16 periodically (every ~10 milliseconds) to track an external high precision clock.Is enabling the DLL calibration (HRTIM_DLLCR:CALEN, CALTRE) en...

Different channels of same the Timer are not working together when using with registers.

The problem that I'm facing is that I have configured Timer 2 of channel 1 as output compare and channel 2 as input capture. Let me give you a brief idea about the logic that i'm using. The on board led's GPIO is configured as output compare and i'm ...

Synchronize 2 STM32 micro using UART and DMA

Hello,I am trying to synchronize 2 STM32 microcontroller's using UART and DMA. System clock is 80MHz. Timer1 is set to interrupt at 1ms with 1us resolution. Synchronization logic is executed every 1ms, Serial Transmission at master/slave side is ever...

hello. i am working on a project using two stm32g431rb nucleo boards. i need to make a connection between these mcu's so i choose I2C as the connection protocol.

the problem is when the master micro wants to tell the slave to send some data, after a random time the i2c connection disrupts and i will get HAL_ERROR Message. i wrote the below codes for master and slave:Master code:  while (1) {  /* USER CODE END...

STM32H7B3I-DK Crosstalk on Analog Channels - Chip Temperature Sensor

Hi,I am using four inputs on ADC1: /**ADC1 GPIO Configuration PA4 ------> ADC1_INP18 PA0_C ------> ADC1_INP0 PB0 ------> ADC1_INP9 PA1_C ------> ADC1_INP1and six on ADC2: /**ADC2 GPIO Configuration - Set in stm32h7xx...

Problem setting up ADC1 on STM32F103C6 to do single programmed read (of Vrefint) - bare metal

I am trying to set up ADC1 on STM32F103C6 "bare metal" (no HAL or LL). I've successfully done this on F0 series without difficulty, but this has me stumped. I've also referred to source code generated by STM32CubeMX (for just this device on this targ...

I HAVE NUCLEO-F207ZG BOARD AND I WANT TO CONTROL ITS I/Os ON MODBUS TCP IP PROTOCOL. AND I ALSO WANT TO PUBLISH ANALOG DATA ON HOLDING REGISTERS ON MODBUS TCP IP. KINDLY HELP AND IF THERE ARE ANY SAMPLE CODES THEN PLEASE DO SHARE IT WITH ME.
