STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi Everyone, Can i use the HAL based library in my code for making commercial product? or Need to use only register based code for making commercial products?
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 ...
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...
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...
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 ...
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?
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...
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...
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 ...
