Resolved! STM32 F4 CANBUS communication issue
Hello, I am trying to program Can Bus protocol with two stm32 boards. I used MCP2551 and VP230 can transiciever but both of them doesnt work or my code doesnt work I dont know. I am programming normal mode. My purpose is when press the any button of ...
Resolved! How to reduce power consumption while connected via CDC USB
I'm developing a board with an STM32L452 and would like to find out if I can improve power consumption while it remains connected via USB (as a device). I've tried putting the device to sleep using the following code: while (1) { // ... do stuff HA...
Sending message from slave to master (SPI)
Hello,I'm trying to send a message from slave to master using spi (I'm using only one stm board) and so far nothing I tried has worked. AFAIK for the slave to send data to master, the master has to initiate communication first by sending clock signal...

Hi im currently using STM32H747I EVK board and working on QSPI ,im able to perform all the QSPI operations in FLASH1 but when u configure it as the FLASH2 nothing works . static void MX_QUADSPI_Init(void){ /* USER CODE BEGIN QUADSPI_Init 0 */ /* USER...
SPI + I2C Example Project
Hi, I am struggling to get SPI and I2C to work at the same time on my project I have tried multiple things (DMA, interrupts etc...) are there any example projects that already have this implemented? I am simply trying to read an I2C sensor value and ...
Problem using Slave to transmit I2C Interrupt
Hi,In my project, I communicate with STM slave I2C. I can receive data via I2C but I cannot send data. As you can see in the photo below, the packetData is filling up, but when you send it, it only sends 0x00. what is the problem? what can I do?
Resolved! Transition from 2x Teensy 4.0 boards to STM32H755xI
Hello everyone, I'm exploring the feasibility of transitioning from 2x Teensy 4.0 boards to an STM32H755XI for a sensor-intensive application. The project involves interfacing with 16 VL53L4CX sensors and managing their data acquisition and processi...
SMT32F407VGT6 / CAN issue
The CAN communication between the main control board (SMT32F407VGT6) and the same server board (STM32F407VGT6) shows that the ambient temperature is below -10 degrees, the communication is abnormal, and the ambient temperature is above -10 degrees! I...
STM32F407 USB OTG_FS - OTG_FS_GRXSTSR register invalid
I'm working on implementing USB Host support for the STM32F407 without using the STM32 HAL. I've followed the datasheet and gotten as far as sending a GetDescriptor packet (though I haven't confirmed that on the logic analyzer yet), but I don't know ...
