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...


Reasons for deadlock in H7 series

Hi all, I've recently begun playing around with Zephyr and made blinky for a custom board with a STM32H755.To test it, I made a complete chip erase and then I flashed the application to the M7 (i.e., its flash area). I can then attach to a debugger i...

Resolved! VBAT & RTC Issues on Circuit - STM32H563ZIT6

I am experiencing issues with the VBAT pin on the STM32H563ZIT6 microcontroller. Specifically, the VBAT pin is not responding properly. I am using a CR2032 CMOS battery for RTC backup, but it is not maintaining the date and time as expected. When the...

I have been trying to transmit and receive from putty through the USB virtual com (CN1) of the core board, I tried with different baud rates and the result is always the same, garbage arrives at the putty, and I am not receiving anything either, it i...

offset and linearity calibration

Hello,I'm working with the offset and linearity calibration on an STMH755.  My board will run the full calibration at production, save off the resulting offset and linearity calibration constants, and then retrieve and apply them at any new restarts ...

Resolved! STM32U5x: USB ECM demo - how to setup host?

I am progressing on porting the CubeU5 project for STM32U575I-EV as Ux_Device_CDC_ECM to a NUCLEO-U575ZI-Q board: The USB enumeration seems to work: I hear the sound and I see also an USB "STM32 CDC ECM" device.BTW: very important to go with the righ...
