Hello, friends, I am a beginner, I do not understand the system, I want to control VESC through the serial port of my stm32f407 development board, but I can not understand the pointer and callback in the routine very well. Can you give me some help? How to write serial interrupt? My own is as follows.Is it true？ Thank you.
void USART1_IRQHandler(void) //usart interrupt service function
{
u8 Res;
if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) //received flag
{
Res =USART_ReceiveData(USART1);// //read data from register
switch(Res)
{
case 0x02: bldc_interface_uart_process_byte(2); break; //
case 0x03: bldc_interface_uart_process_byte(3); break; //
default: break;
}
}
