STM32 MCUs Products

The board I used is STM32G030. I don't know and I set the protection level to 2, so the board and debugger can't communicate. I want to go back to protection level 0, how do I do it?

Triggering Timer1 from Master HR Timer (HRTimer)

Hello, I am working on STM32G474. I want to trigger Timer 1 from HR timer. I.e. Timer 1 must start after some delay of HR timer A. I made following settings but it is not working. could you please guide me how to trigger Timer 1 from master HR timer.

Controlling the ad5675r using the stm32's HAL library

Hello!I am a beginner and I am trying to implement a simple I2C communication with the DAC AD5675R using the STM32h723zg Nucleo board, I would like to start by having the first channel of the DAC output a voltage (say 2V). I have connected the +VOUT ...

Failing to use SWAP Output 1 and Output 2 function.

Hi, I am trying to use SWAP Output 1 and Output 2 function for HRTIM running with the deadtime function enabled. The description for SWAP function in ref manual says that "the HRTIM_SETA1R and HRTIM_RSTA1R are coding for the output A2, and the HRTIM_...

Configuring ADC with DMA in circular mode with end of conversion interrupts.

I have setup ADC conversion to be triggered by Timer 3 and DMA is configured [in NORMAL Mode] to transfer data from ADC to a buffer. I am able to get this to work and I call HAL_ADC_START_DMA() from the HAL_ADC_Conv_cmplt_callback() to restart the DM...

I use DAC sawtooh mode(STM32g431c8T6), Decrement mode.Does the value of DAC_DOR equal to the value of DAC_DHR ?

The STM32L431 RTC clock is slowing down

We tested the RTC clock and found a phenomenon that the system kept VDD3.3V in standby state and then disconnected VDD3.3V in standby state, but the RTC clock did not run slowly. If the system controlled automatically and disconnected VDD3.3V in slee...

How to interface an external ADC for highest speed?

Hello, I am planning to use the STM32H7A3ZI for a personal project and want to achieve the highest speed possible with an external ADC while storing at least 16 million samples in an external memory. In the tenths or hundreds of MSPS range, ADCs tend...
