How to make LED (LD2) in NUCLEO-G474RE stop blinking ?
Hi everyone,I am trying to play around with the demonstration application included in the NUCLEO-G474RE. The user LED (LD2) blinks at 3 different frequences (increasing order) and one can shift between them by pressing the B1 switch (blue switch) and...
NSS pin mode
Hello,I'm using HAL_SPI_Transmit function to transfer two bytes over SPI, NSS pin controlled by SPI module. I noticed that NSS pin is changing state after each transmitted byte. I need that NSS goes low before transmission is started and goes back to...
NUCLEO-STM32F446RE: TX working, RX not
Hi!I am using a NUCLEO-STM32F446RE and HAL which was created with CubeMX. I can send messages via CAN to my test PC. Messages which are sent to the NUCLEO board are correctly acknowledged from the NUCLEO board. So I assume that HW wiring, CAN transce...
