UART receive interrupt issue HAL_UART_Receive_IT remains BUSY
Hi ,I am using HAL_UART_Receive_IT(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size) HAL api for uart receive interrupti am calling it at end of HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)it works for some time but after some time HAL_...
Resolved! STM32F446RE Timer Interrupt and UART Interrupt Doesn't Work With Each Other.
I have Timer 2 interrupt and an UART 4 interrupt for reading from a GPS module. But they don't work with each other. When I disable Timer 2 interrupt UART 4 interrupt starts to work.I did set Timer 2 interrupt preemption priority to 1 and UART 4 int...

Resolved! Is there a replacement for the STM32F4 discovery kit?
I am starting a project which involves a CMOS camera. I only need to take still images, not video. I would greatly prefer being able to use a microcontroller over an SBC or FPGA. STMicro used to have an STM32F4 with a camera daughter card, but it app...
RTC subsecond alarm wake from STOP
I am building an application that requires maximum power efficiency. We have decided to use an STM32L031K6 MCU. Our application requires waking up at specific times to power on other external devices. Because the system sleep times can range from ...
Resolved! STM32F767ZI and CAN-Bus: Bus-Off error after receiving 8 byte long message
Hello everyone,i am currently trying to get the can bus on my Nucleo-F767ZI running.Now i got a problem that every time i sent a message via CAN (from my PCANView) which is longer than two bytes i got a Bus-Off error, but if byte 2 is not empty i ca...
NVIC register base address problem
Is there somethings wrong with my STM32F407 Discovery board, the base address of NVIC register display in Debug section is very strange! Please give me some advise in this case
No interrupt callbacks for CAN-bus in STM32F3 series
Hi!I'm trying to get J1939 to work with ST's CAN-bus, but it seems that I got some smal issues with it.First I need to make sure CAN-bus working and I think I have forgot something.First I know my baudrate of the ACU(Actuator Control Unit) want is 25...
