NucleoF303K8 NVIC_Init() hang Posted on January 27, 2017 at 13:40
Hi, everyone! I am working on a NucleoF303K8. I am using the standard periph library. I am trying to use USART interrupt in my project, but being held by a problem. When I NVIC_Init() the USART interrupts, it hangs. When I comment out the NVIC_Init() call, It works. I am new in STM32 programming, so I don'thave much to find the cause. I have replaced the startup files, some from the cube libandsome from the std library, not work.When I use the CubeMX to generate the hold project, it work with the USART interrupts. Since some requirements are not fit with the HAL library, so I use the std library. The following is my code:
Hoping someone can give me a little help, thanks a lot!
int main(void)
{
board_init();
uint8_t c = 1;
while(1){
GPIO_SetBits(GPIOB,GPIO_Pin_3);
Delay_us(1000000);
//Serial_Write(&Serial2, c);
USART_SendData(USART2,c);
GPIO_ResetBits(GPIOB,GPIO_Pin_3);
Delay_us(1000000);
}
}
void board_init(){
GPIO_InitTypeDef
