It looks like (based on PCB and schematics) - I cannot run the VDDIO (all IO pins) with 1V8.No option on this board to jumper IO voltage as 1V8 - why not?"rrrrrr": I was thinking to change all my projects to this great board (speed, memory size), e.g...
I'm in trouble with the high err rate of ADC123_IN1 in "STM32 Nucleo-144 development board with STM32F756ZG MCU".I've purchased two of the same thing, and both of them have trouble in ADC123_IN1.I had tried 4 channels: ADC123_IN1, ADC123_IN4, ADC123_...
Hello Everyone,I have been trying for 2 days to solve this.I keep going around in circles.I have found various similar posts both here and on Stackexchange, but I am still stuck. === Here is error message when creating a new STM32 Project."Code gener...
Hi, I am trying to use a timer triggered ADC sampler with DMA and a complete conversion-triggered callback function. I followed this guide (https://www.youtube.com/watch?v=_K3GvQkyarg) while configuring my single pin (channel) input for ADC. Specific...
Hello, I've a STM32F411 board. Unfortunately, I was distract when I plug the SWD with ST-LINK. I've invert the VCC and the ground (Not really a good idea to plug VCC and GND at each opposite of 4 pin connector). Now, It's seem not working.. I m...
I am using the STM32H747-I Discovery Board. When I connect the CN2 power supply to the board, it turns on, and LED5 lights up green, indicating the board is powered. However, the LCD display does not turn on. I tried enabling the backlight by setting...
I am a beginner working on performing FFT with the INMP441 sensor using my STM32H747I Discovery board. Initially, I experimented with arm_math.h, I2S communication, button interrupts, and enabled SWD for debugging. However, after these changes, any c...
I got my STM32H745I-DISCO (STM32H745XIH6U) kit and wanted to update st-link (STLINK-V3E) firmware. Unfortunately I used unreliable USB cable and it got probably disconnected during the process. Now the STLinkUpgrade shows the line "Unknown firmware t...

Hi everyone,I’ve noticed that many STM32 development boards include two microcontrollers: a main controller and an additional smaller-range controller. For example, I have the STM32L476 Evaluation Board, which features the STM32F103CBT6 as the second...
