SPI between F769I and F446RE not working
Hi,I'm trying to implement a basic SPI full-duplex between two STM32.I have set up an F769I as Master, which works just fine. However the F446RE Slave doesnt transmit anything.I used CubeMX to create the project (file attached).The Master currently d...
Bug report: STM32F4 Cube 1.18.0 HAL CAN driver generates incorrect code.
Cube 1.18.0 appears to generate HAL CAN code in can.c and can.h which is aimed at the 1.21.0 redisigned CAN driver.The code refers to member variables which do not exist in the 1.18.0 register structures, for example: hcan1.Init.SyncJumpWidth = CAN_S...
LoRaWAN Rx2 timeout not being triggered for confirmed messages
Hi,We are sending confirmed messages. Every once in a while, we do not receive a confirmation from the gateway, which is fine. However, sometimes we are not seeing the callback in the ST LoRaWAN stack being triggered as expected. I expect the lack of...

TIM2 interrupt fires twice when optimize speed is set
Hello,I just test some interrupt stuff with Nucleo F439ZI and found that simply setting optimize to -Ofast leads to a timer 2 interrupt (compare event when generating a PWM) firing two times, while -O0 shows the expected behaviour. I test this with a...
Cubemx pwm for stm32f7 nucelo board
Hi there. I'm trying to generate a Pwm signal using my nucelo board but I'm having issues doing this using cubemx. I've configured the clocks and oscillator based on resources I've found online but I'm not too sure what the clock source should be. I...
