stm8L152 PC2 is USART rx,
1 rx to exit before halt()
USART_DeInit(USART1);
GPIO_Init(GPIOC, GPIO_Pin_3, GPIO_Mode_Out_PP_Low_Slow);
GPIO_Init(GPIOC, GPIO_Pin_2, GPIO_Mode_In_PU_IT);
RX_EXTI_setup();
EXTI_ClearITPendingBit(EXTI_IT_Pin2);
2, pc2 exit handler
INTERRUPT_HANDLER(EXTI2_IRQHandler,10)
{
/* In order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction.
*/
//stop_flag = 1;
EXTI_ClearITPendingBit(EXTI_IT_Pin2);
//GPIO_Init(GPIOC, GPIO_Pin_2, GPIO_Mode_In_PU_No_IT);
// 1230 change
GPIOC->CR2 &= (uint8_t)~GPIO_Pin_2;
//write_usb_flag();
FLASH_Unlock(FLASH_MemType_Data);
//FLASH_EraseByte(0x1000);
//delay_ms(20);
FLASH_ProgramByte(0x1000, 0x66);
record_time_f = 1; // to record time
//write_addr
FLASH_ProgramByte(0x1002, (uint8_t)(write_addr & 0xff));
FLASH_ProgramByte(0x1003, (write_addr >> 8) & 0xff);
FLASH_Lock(FLASH_MemType_Data);
}
could you help me review the code?
it works, but i want to know if here have some bug?
