已经修改过了是这样吗?
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);
}
问 使用W806串口UART2,为什么一旦发送就出现设备中断?
