Do you know STM32 Step-by-step ?

Hi all! We have created for you a new online-education program: STM32 step-by-step. It is a learning program, part of the STM32 Education initiative, designed for anyone interested in getting started on building projects with the STM32 microcontrolle...

I'm sorry for my bad english! I am trying to use stm32f103c8 board uart 9600 9N1. I am sending 9 bits of data. but I am missing 9 bits of data. How can I read 9 bit data? It does not matter binary or hex, but I am trying to read 9 bit data completely.

I am trying to create an MDB / ICP (VMC) library for stm32f103 and I need to read and write 9600 baundrate 9N1 features! but hal_uart_receive () function gets 9 bits of data wrong! can you help me?

Pausing a STM32 TIMER

Hi, I am using the STM32F401RE microcontroller to control 4 seven segment displays which together represent a countdown timer.In order to control the displays I am multiplexing and therefore using the general purpose TIMER 2 in interrupt mode for a f...

Reading Accelerometer Data to Make a Tilt-Compensated Compass

I'm making a tilt-compensate compass using an STM32L476RG, an MMC5983, and an LIS2HH12. I am able to get a compass heading and tilt and roll angles but the tilt compensation seems to make the compass heading error worse. I have calibrated both the ma...

DMA-> GPIO STM32f103

Hello,I need to transfer 42 pulses (with 1 pin of a port) and read incoming bits from 1 pin of a port( such as SPI communication). As this forum member trained me I am curious to use DMA to generate 42 pulses with sending a specific value(10101...). ...

STM32F769 EVAL DMA for TIM2 PWM occurs only once, why?

I am trying to set-up a PWM with 20kHz pattern and every time the PWM is over to add a new one. I am using to start-up the DMA if (HAL_TIM_PWM_Start_DMA(&TimHandle, TIM_CHANNEL_3, SamplingPoints, length) != HAL_OK) functionFirst time the pulse is sen...
