I’m currently working on a project that involves I2C communication using the STM32H750B-DK but I’m having trouble identifying which I2C peripheral (I2C1, I2C2, etc.) is connected to the Arduino I2C pins (SDA/SCL) on the board.Unfortunately, I couldn...
Hi everyone, I’m currently struggling to understand the behavior of the power line on the Nucleo-H753ZI board. My goal:The Nucleo board should be programmable via CN1 (Micro USB, ST-Link connection to PC). When connected, this should provide both 3.3...
Hey everyone, I'm working with the STM32H747I-DISCO board and trying to get it into USB DFU mode to flash firmware using STM32CubeProgrammer. However, the board isn't being detected, and I couldn’t find clear instructions in the documentation about h...
Hello everyone!I've designed a PCB around the STM32H7B0 MCU (I've attached a screenshot of the relevant part of the schematic) for audio signal processing. I wanted to use the maximum clock frequency of 280MHz, but this requires the use of Power Reg...
Can the STM32H757I-EVAL board accept microphone output in formats other than DFSDM or PDM?
Hi,I am working on a project using STM32H757I-EVAL. I wanted to know what the model number of the microphone present in STM32H757I-EVAL. In the user manual, I could just find it as ST-MEMS digital microphones. Also, does it support external microphon...
Hi ,I'm working on a code to collect data from a load cell wit HX711 cip. I'm using STM32CubeIDE.I configured GPIO pin 6 as Clock output for the HX711 but when calling HAL_GPIO_WritePin the output pin PA6 does not change.The hardware configuration is...
I am currently using the STM32F103C8 board, in this, I connect the OPTOCOUPLER input to the PA6 PIN of stm32 which is the PWM pin, and at the output side I connect the optocoupler's output to the driver's 10v + pin and optocoupler's output with 10v ...
Hello, I made a custom board using the STM32C031K4T6. I have tried several times now to connect to the chip using STM32 Cube IDE and the STM32 Programmer, both didn't work. The ST-Link gets recognized. I have tried different combinations regarding th...
Custom board will not run without debugger. With debugger removed and cycling power I have manually touch NRST to ground to get it to run.The NRST is only connected to SWD pin, but when debugger is removed it is not connected. Theis is no ST-LINK o...
