Resolved! STM32F412G-DISCO: Turn on LD6 (PWR) LED when microcontroller is powered on

We want to turn on the LED when the microcontroller is powered on. Before the program is executed.Is it possible to achieve this with just the program, without changing the HW?Specifically, we want to program LD6(PWR) of STM32F412G-DISCO.

Identifying Debugger for STM32H503KB MCU

Greetings, We are planning on using STM32H503KB MCU at 250MHz for our application. We have tested our code on NUCLEO board MB1814B which had an internal debugger IC STLINK-V3EC. For development what is the debugger tool that we should procure for eas...

What's the Correct Power Supply Scheme for H725/735 VFQFPN68 Package?

Since the VFQFPN68 package doesn't provide the VDDLDO, should the chip work just with VDD/VBAT/VDDA all connected to 3v3?Updates: during my unit test, I kept only the STM32H725 chip on the board and removed all the other components. Then I powered th...

Resolved! Could someone suggest me a board?

Greetings.I have a project I developed on ESP32 (CH340 Chip). For some reasons, the project got messy, and I would like to migrate to a new board. I have an STM32 Nucleo which gave me a lot of satisfaction, but for this project I need something-Small...

Resolved! STM32H573I DK STMod+ connector pin 18

The STM32H573I Discovery circuit diagram (MB1677) shows pin18 of the STMod+ connector going to PB12.This should be the BOOT pin of the MXCHIP EMW3080B (MB1400)But H5 Cube configures PB0 as BOOTSTM32Cube_FW_H5_V1.3.0\Projects\STM32H573I-DK\Application...

Resolved! programming whitout nucleo or Discovery

Programming the stm32f103c6 and stm32h753zi chips, without NuCLeo or Discovery, only chip, connections, pins, ports etc.. where can I find information, thanks!!

Resolved! Battery powered B-U585I-IOT02A

I'm building a simple application that collects environmental data from sensors (pressure, temperature and humidity) using the B-U585I-IOT02A development board. Since I want to deploy the node directly on the field, I'm planning to power the board us...

Resolved! ADC not filling all the buffer with DMA

Hi, I'm using a Nucleo-H723 board and I need to sample 4 ADC's with variable sampling rate, maximum 1Mbps.I configure the TMR2 with the time stamp (10ms, 1ms, 10ms, etc...), and TMR3 with the sampling rate that is the input for the ADC trigger.Values...

Resolved! STM32H7S78-DK/MH1736 cannot detect st-link

I downloaded the boot code generated by following the settings in Figure 3 (the frequency configuration to 600Mhz) into the flash of the 0x08000000 starting address, and then the stlink cannot detect after re-powering (as shown in Figure 1). But my ...
