Resolved! How to implement level triggered interrupts with EXTI

Edge-triggered interrupts had been used by us to identify various system states. However, it appears that the interrupts are now sometime erroneous and cause an undesirable state change. This led us to search for implementations where level-triggered...

Resolved! STM32G0B1 ADC DMA multichannel

Having some trouble with reading ADC channels on this unit only when using multiple channels. I have no problem using a single channel, but as soon as I expand it to two, or more, my readings are just garbage.Code for working single channel: hadc1....

Resolved! ADC conversion data to DMA without any DMA interrupt ??

Hello team am Receving 16bit ADC conversion data to DMA in STM32H745i Disco in CubeIDE software. Here DMA interrupt is generating by default in software (i am disabled the interrupt in programming after that program counter is out of control) I dont ...

STM32H730 FDCAN TxDelayCompensation

I use FDCAN in STM32H730 for communication over CAN-FD.At the moment it works with 500kBit/2000kBit without TxDelayCompensation. But we want to communicate with 1000kBit/4000kBit too. Therefore I want to enable TxDelayCompensation.I'm not sure how I ...

Resolved! NUCLEO-U575ZI unable to activate PWM pin output

Hi everybody! I keep trying to out a PWM signal, using TIM1 ch1. CC do trigger fine, but the output pin doesn't change. Please help!void TIMER_init(void){ //PA8 - CH1 GPIOA->MODER &= ~((3 << GPIO_MODER_MODE8_Pos) + (3 << GPIO_MODER_MODE9_Pos)); //Sw...
