How do I modify the transfer mode of DMA while DMA is running?
I need to change the working mode of the DMA from the general mode to the circular mode, but I don't know if HAL provides a modification method, or other modification method

Resolved! Setting Encoder functionality on STM32F407VE vs STM32F103C8
Setting the encoder functionality on STM32F103C8 is straight forward, just set the registers that's due. But on STM32F407VE it seems more tricky: using PA6 and PA7 on TIM3, if you follow what is said in the RM0090, page 616, you're not ready to go:Fu...
Problem with reading Status Register of W25Q80DV with QSPI
Hello together! :) I am trying to read the status register 1 of the QSPI Flash W25Q80DV via QSPI. Unfortunately I don't get any data in the buffer. I only get 0x00. The topic of QSPI is still very new to me, so I may have overlooked something obvious...
TIM8_CH2N for PWM
I try to setup the PB0 for PWM mode to drive a LED.When I use the TIM3_CH3, it is working with the following code.But it does not work for TIM8_CH2N.I suppose something to do with the "N" but could not find out what in HAL code should be changed.TIM_...
Using DAC output for class D audio amplifier
I'm wondering what would be an ideal circuit to connect a very simple 2-4W class D audio amplifier to a DAC output of an STM32 MCU.My goal is to be able to play some WAV files using build-in DAC of STM32F051.I found an amplifier TDA2822G-S08-R, took ...

How to establish UART communication between two microcontrollers
I am trying to transfer sensor data collected on a NUCLEO-144 L552ZET6Q board to a Sparkfun Artemis BLE Module via UART DMA. However, I can't get the STM32 to send anything on any UART besides messages to TeraTerm using the basic HAL_UART_TRANSMIT fu...
Resolved! What could be the cause of a constant voltage offset on the STM32L041G6 ADC?
I have been testing the ADC on my STM32L0 with 12-bit resolution and for some reason, every measurement I take has a 0.048 V offset. I've tried a different supply voltage (from 1.8 V to 3.3 V), but the offset stays there.This offset starts at the fir...
Resolved! Correct order of using HAL_ADC_RegisterCallback function
Dear ST Community,as part of a project to capture analog microphone data, I would like to use my own callback funtions instead of hal callbacks. For this I register my ADC callbacks with the HAL function HAL_ADC_RegisterCallback as follows:/*********...
