STM32 MCUs Products

New possibilities for the ultra-low power segment!

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...

Issues with Teseo Suite and Teseo VIC3DA EVB

I'm trying to figure out how to configure the device using the NMEA packet scripts available in Teseo Suite. The problem I'm facing is every one of my PSTMSETPAR packets is being met with an error, even when using the example scripts provided.I am re...

Resolved! SPI writing - 1 bit off

I have a peripheral I am communicating to using both a Raspberry Pi and also STM32G0B1 (two different devices, two different setups)I am basically trying to reproduce successful communications that the Pi us doing to this peripheral on the STM32 plat...

The STM packaging usually only contains one digitally legible item: BULK ID in 1D code. How do I get digitally information about Datecode, Partnumber, Qty etc, is it anywhere encrypted or saved in RestAPI ?

General question to traceabiliy

Data transmission is not happening using SPI ?

Hi Team, I am using the STM32H745ZI-Q nucleo board . I am Trying to Transmit the data through the SPI using LL.Here I am using one nucleo board cm7 for transmition and I am using another same model nucleo board cm7 for the receiving. In the transmiti...

Resolved! What is the Clock Speed of the SDRAM FMC on the STM32F469?

Once again I'm struggling to find a clear source for a peripherals clock with STM32 MCU's.Most searching leads me to HCLK/2, so at a max HCLK of 180MHz I get 90MHz.However, looking at there reference manual for the STMF469 I see this:From an example ...

UART DMA error

I'm using a STM32L062 MCU to interface a BLE module via UART. I have setup DMA with idle line detection to receive data of unknown packet lengths. I'm receiving packets from the BLE module and the software seems to be working fine. However, I noticed...

Why does SPI communication with DMA in STM32H745ZI (NUC-H745ZI) using example code is giving varying output?

Hi, I'm using the NUCLEO-H745ZIQ device, and I'm starting with SPI. I used the "SPI Full Duplex communication with DMA example code" in the repository available from "st" (STM32Cube_FW_H7_V1.10.0 folder). It is giving me the expected output but somet...

I would like to drive STM32L011D3 GPIO in output to "1" or "0" with a minimum of instruction. I think we need:1 LDR + 1 ORR or AND + 1 STR = 3 instructions and 5 cycles Is there a more cycle-efficient way to do this?

Is it possible to set an output to "1" or "0" with an instruction of one cycle?

Resolved! What is the detailed difference between VDD_FT and VDD?

Hello, ST expertFrom the picture below, it showes that 5V tolerent GPIO connect to VDD_FT through a protection diode. But what is detailed difference between VDD_FT and VDD? BRYang

single DMA buffer for two timers STM32G0xx

Hello. In a project with stm32g030 (071) I use two different timers to generate two PWM signals. The triggering of timers and PWM signals is out of phase by 180 degrees. Can I use one DMA buffer to load data into CCMR registers of two different timer...
