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...
Hello,I have 3 boards with STM32F205RBT using 2xDAC and 9xADC. Two boards are working just fine but one board has the second DAC output inverted (write 0 ->3V, write 4094 ->0v). The same program is used, boards are the same. The DAC output is amplifi...
What's going on is that I finally got my low pass digital filter working on the STM32H753ZI using the PMODI2S2 peripheral and I noticed the output signal is extremely low ~340mVpp this is after the biquad filtering. If I take out the low pass filteri...
I’m working with an STM32G474RE chip, and I’m trying to use the synchronization feature of the DMA multiplexer to time when a DMA transfer to SPITX should occur. I’d like to have this timed synchronously to some other timer events.Looking at the docu...
Dear ST Hello,I am using the ST example for SPI communication for getting started with STM32F429i-discovery.This the header of the main file. ****************************************************************************** * @file SPI/SPI_FullDuple...
Hi,I'm working on a project with a STM32L475RC and I'm facing problems with the SMBUS.The STM32L475RC is used as a SMBUS/PMBUS Client. As smbus/pmbus stack I use the X-CUBE-SMBUS Expansion Package (AN4502).Now I'm facing problems with block transfers...
In my opinion one of the simplest ways to receive an unknown amount of data has been this post which details how to use IDLE line detection to trigger the DMA to call the HAL_UART_RxCpltCallback function. This then reads the data received via UART fr...
In a similar question it is recommended to carry out the instructions:void HAL_UART_ErrorCallback (UART_HandleTypeDef * huart){ // I implement this .. but eventually you can decide with different approach // Many macros / proc on this code .. is just...
I am trying to jump into embedded world but i have very less prior experience .... I have been programming PIC16f877a and i felt comfortable with it but now i want to go deep ... Should i opt for STM32 ?Thanks in Advance
Hello guys,I'm not new using DFU but I have this strange problem.When I try to jump in DFU from my code, I get an "Unknown usb device" from my PC.I have also 2 push button in my board. Reset and DFU pin (keep PH3 high ).If I keep pressed DFU button a...
