已經修改過了是這樣嗎?
include "wm_hal.h"
define readl(addr) ({unsigned int __v = ((volatile unsigned int ) (addr)); __v;})
__attribute__((isr)) void CORET_IRQHandler(void)
{
readl(0xE000E010);
HAL_IncTick();
}
extern UART_HandleTypeDef huart2;
__attribute__((isr)) void UART2_4_IRQHandler(void)
{
HAL_UART_IRQHandler(&huart2);
}
問 使用W806串口UART2,為什麼一旦發送就出現設備中斷?
