Trigger HRTIM capture via SW (i.e. EXTI event)

I use the HAL to setup multiple HRTIM timers on a STM32G4 and I would like to trigger a simultaneous capture across them using software (the reasons for this are complex but it needs to be a simultaneous capture).Currently I have a GPIO output pin lo...

Typo in Getting_started_with_EXTI

In Getting_started_with_EXTI there is an error:NucleoFL476RG -> NucleoL476RG

What is accurate way of generete microsecond delay function without systick timer ?

Here is my code, but its not working correctly void DelayMicros(uint32_t micros) { uint32_t multiplier; multiplier = SystemCoreClock / 4000000;   micros = micros * multiplier - 10; /* 4 cycles for one loop */ while (micros--)...

Hi, I've purchased an STM32H723ZG Nucleo Board to evaluate and test the potential of the onboard DAC. The max sampling time for the STM32H72x with the max bus speed at 137.5MHz is 51.1Msps as described in the AN4566 but I can't reach them.

I'm trying to generate a 1.2 MHz sine burst using the DAC, DMA and Timers. Everything works fine but only up to 200-250KHz then increasing the frequency the amplitude begins to decrease.Moreover I've managed to reach about 25Msps and it seems impossi...

I want to use a DHT11 sensor with a nucleo-f429zi board, what should I do?

How to receive data by using SPI communication ?

I use the STM32Lo538 disco board, and this board is connected to one sensor. Moreover, the protocol of this sensor is SPI. I faced difficulties receiving the data from the sensor. When I watched the waveform of this sensor, I noticed that the CS pin ...

Timer Encoder

Hi, I am using STM32F105 MCU.I have made a mistake in Hardware and switched two pins around. I have two signals from a encoder which they are connected to MCU in wrong way. SignalA ---> PC9 (TIM3-CH4)SignalB ---> PA8 (TIM1-CH1)I want to use a combin...
