What's the bXCAN RXD recessive signal on STM32L476?

I'm reading RM0351 for STM32L476, "To be synchronized the hardware has to monitor a sequence of 11 consecutive recessive bits on the CAN RX signal." Is RX recessive bit a digital high or low signal? I couldn't find the info on the datasheet which onl...

My data are being send in loop despite the datas are ACK.

I am having trouble getting the timer working. The count is always returning 0

Here is my system clock config, my Timer 2 initialization, and the read function.void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct; RCC_ClkInitTypeDef RCC_ClkInitStruct; RCC_PeriphCLKInitTypeDef PeriphClkInitStruct; __PWR_CLK_ENABLE...

Hi I am using STM32L476VGT3 in my design. For vibration and shock simulation, I would like to know the weight of the component, I couldn't find this information in the datasheet. Could you provide the information ?

STM32 Dual Core using peripherals (UART) with both cores - best practice?

Hi folks,recently, I started working with the STM32H755 dual core processor. With having 2 cores connected to the same peripherals, more opportunities and problems arise.Currently, I have a setup where I run FreeRtos on the M7 core and bare metal cod...

How to make PWM one shot output?

Hello, I need to make software triggered one pulse output for 300 ms. The question is what is the best way to do this? I have found that PWM can work in one-pulse mode, but it looks like it requires external trigger to start, which is not an option f...

Example software for STM32H747I-DISCO (STM32H747XI)

Hello, this is my first project with stm mcu and my development board is on the way. I would like to make a hobby wav player and I have found a rather good recipe to start with - AN3126 Application note "Audio and waveform generation using the DAC i...
