How can we do the simple UART for the STM32H745I-DISCOVERY board using the MDK-ARM?

I am using stm32h745i-discovry board as my development in the arm keil. Here I need the uart communication . could you please send me the example code for this.

Is it possible to create RAM section for stm32l151rd? (It has only 1 Ram area)

Hello,I know that it is possible for mcu which has several ram areas such as RAM_D1, RAM_D2 like STM32H7. STM32l1 has only one RAM. Because I can not divide RAM for some important data. But I saw an STM32L1 example created on KEIL and divided some ad...

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...

Resolved! Using the Joystick Inputs as EXTIs

Hi, Guys...So I got the H757I Eval Board as a gift and am trying to learn MCU Programming with it. I guess STM thinks that: if you have such a high end board, then you should already know what you are doing, because the documentation is poor and they...

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...
