Nucleo-H755ZI-Q no longer programmable
This fault has appeared very abruptly. One hour ago I was working with the board just fine, programming via STM32CubeIDE. Then I swapped the board to a different USB port on my laptop, now it is not programmable.When I hit the 'Run' button, it appea...
High Current Consumption in STM32 NUCLEO-H745ZI-Q in Standby Mode
I am working with a Nucleo-H745ZI-Q development board and want to put it to standby mode to measure current consumption. I have put the domain D1, D3 in M7 and then domain D2 in M4 in standby mode. I also use 1 user LED for each core, so that I can k...
Resolved! Interfacing of STM32 H747I-DISCO Board with B-CAMS-OMV Camera Module
Hello All, I'm currently working with the STM32 H747-DISCO board, but I'm encountering some difficulties in interfacing the B-CAMS-OMV Camera Module. The LCD is functioning correctly, but the camera is not working (even though the 3 LEDs are lit). I'...
SPI Loopback test on stm32h563zit6
HI, STM Experts, Using STM32CubeIDE, I configured a project with default settings for the STM32H563ZIT6 (8 MHz external clock), running at 250 MHz. Additionally, I've enabled SPI1 for full duplex communication (transmitting and receivi...
Expert Advice Needed for GUI Handling on H753(single core) with 1280x800 TFT RGB Display
Hi ST-Community Members,We have chosen the H753BI MCU as the main unit for our project, utilizing 32MB SDRAM and 128MB parallel NOR flash. We are nearing the final prototype model, but we need to finalize the GUI and hardware. We selected a 1280x800 ...
STM32F746 cannot read level of audio input signal
I would like to read the level of audio input signal to use like a vu-meter instead of use analog input. This is my code but I read always 0dB on both channels. void AUDIO_PLAYER_Init2(){/* Allocat mem for Smr */pSmrPersistentMem = malloc(smr_persis...
HID device to be connected to STM32F769I-DISC0
Hello!After it was clear, that the STM32F469I-DISC0 does not support the HDMI output feature, I purchased also the STM32F769I-DISCO to be able to evaluate the connection of a HDMI monitor to the board.I need to connect a keyboard to the board and my ...
Resolved! Question about the STM32F429 board
Hi, I'm having some problems with the STM32F429 DAC testing. I have two boards of the same type. On board 1, the Digital Storage Oscilloscope shows that the sine wave voltage ranges from 2.08V to 2.94V. However, on board 2, with the same program and ...
