Hello,I want to trigger a SPI-transfer with a timer. Its like in this post:https://community.st.com/t5/stm32-mcus-embedded-software/stm32g4-trigger-dma-request-from-spi-to-memory-with-timer/td-p/726370but I want that an output compare of a timer that...
RTC Timestamping Delay?
Hi everyone,currently I am working with an STM32L431 on a project that timestamps incoming IEEE802.15.4 frames via an AT86RF233 radio. The radio module is configured to issue an interrupt when a message is received and this interrupt signal is connec...
Resolved! RTC Wake-Up from Stop3 on STM32U545RE
I would like to use the Stop3 low-power mode on an STM32U545RE (NUCLEO-U545RE-Q board) and to wake-up the device by the RTC. I have a working example for Stop2 mode for which I largely used the inspiration from the stm32u5 workshop. But when I replac...
