STM32 MCUs Products

After stopping a PWM Output (HAL_TIM_PWM_Stop) the signal is slowly decreasing instead of switching instantly to low (0 Volt).

How to change DMA from 16bit to 8 bit transfers

I have inherited a wadge of working SPI DMA code for a product. I want to send bytes rather than 16 bit words. In order to change the length of the SPI packets from 16 clock cycles to 8, I changed the DMA_CCR1_MSIZE & PSIZE fields in DMA1_Channel3->...

I need to perform hardware reset after successful update of software through UART. In other case the MUCUs program doesn't start. Is it normal? The part is STM32F030RCT6TR

STM32G070. In the code generated by the CubeMX, there is the colock source is selected for the TIM1/15, TIM1CLockSelection/TIM15CLockSelection. But in datasheet, the clock source is only TIMPCLK and no other source. I think this is the tool bug.

void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Configure the main internal regulator output voltage  */ HAL_PWREx_ControlVoltage...

Programming alternatives of the STM32H750VB

Hello,​I would like to ask a question further to my recent one about the Value Line STM32H750 3 weeks ago or so.The chip has 128KB Flash and 1MB RAM.Assume my program is bigger than 128k and I decide to use NOR Flash as a storage and to run from the ...

Just how powerful are STM32s?

I'm sure this is a pretty loaded question, especially considering that there are a range of them out there now, plus I'm sure it also varies based on application(s), ​im just curious because I am coming from an Arduino world (and going to school to g...

Parallel synchronous transmission using GPIO and DMA. Which chip to use to receive data under 20MHz?

I found the doc AN4666 and AN2548, but I could not come to a conclusion.I have the STM32F103C8T6, but when performing a sequence of 1000 readings, the average time was of 266us, approximately 3.759398 MHz.I would like to know which chip model should ...
