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...
Hi all,I have trouble with receiving one byte on SPI1-DMA1. All is working if I set more bytes to transmit/receive (2 and more) but when I try to send only one byte it do not trigger interrupt on Rx channel (DMA1 channel 2).I can see transmitted byte...

Hi All, I am trying to use STM32F401 NUCLEO Board to talk to ST IMU LSD6DSL. LSM6DSL supports burst mode read, but I can not find a way to implement SPI burst mode from the stmf401 s library. I am wonderinf if there is any way to implement a SPI bur...
Hi,I am using stm32l431 and work with LPTIM in stop2mode. When the mcu wake up after stop mode, i2c stop working, so I need to restart mcu.It's strange because in some cases the i2c work in the next 3 wake up, but after this dont work anymore. Should...
