STM32H750 Discovery kit Clock Generation on GPIO Pin @ 10Mhz speed using DMA (Memory to peripheral copy).Clock is not coming properly and it is ringing

How can i generate a master PWM that can vary from 1 to 70% of duty cycle and other 2 PWM with 50% but all with same frequency?

I would like use M4 core as master and M7 core as slave. Can I reset M7 core until M4 is fully initialized its peripherals just after power ON? If yes, how can i implement in software or hardware?

I am new to this Nucleo development board so your help much appreciated. I bought Nucleo -F302R8 and i follow 'Nucleo Boards Programming with the STM32CubeIDE by Dogan Ibrahim. The projects use Nucleo L476RG. Data spec same(?). Will it work?

My STM32F103C8T6 won't enter programming mode.

Hi!I'm a newbie to all of this. I purchased an STM32F1038C8T6 development board or "Blue Pill" recently.I connected it to my PC Windows Using a Usart to serial converter.I read that I should put one of the BOOT Jumpers in the one position to enter pr...

HAL SPI RX function problem: long delay between two cycles of SCK during HAL_SPI_Receive() execution

Hi all!I've found some strange issues during my reception of data at SPI interface using HAL functions.The problem is that between each two complete cycles (8 periods) of SCK signal, the SCK line stays idle without reading any data. With longer strea...

Receiving incorrect responses from STM32G071RB with 9600 baudrate

Hello!I am very new to STM32 boards and MCU-s overall. I am using a Nucleo-G071RB and I implemeted this Modbus library: /ceremcem/modbus_lib. For testing I use Comtest Pro. The code was working without issues on a Nucleo-F446RE. On Nucleo-F030R8 I am...

ADC DMA data order sometimes is wrong STM32F303RBT6

I may have seen other posts discussing this topic, but neither of them helped with this. Does the ADC in the buffer we send to the DMA put the data in order? or is some bug in the code? I'm reading for 3 analog values and sometimes, it works correspo...
