STM8的外部中断程序
Sure! Here's an example code for configuring external interrupts on the STM8S microcontroller:
```c
#include <stm8s.h>
// Interrupt handler for external interrupt 1
INTERRUPT_HANDLER(EXTI1_IRQHandler, 7)
{
// Your code here
}
void main(void)
{
// Disable interrupts
disableInterrupts();
// Configure external interrupt parameters
EXTI_SetExtIntSensitivity(EXTI_PORT_GPIOC, EXTI_SENSITIVITY_FALL_ONLY);
// Enable external interrupt 1
EXTI_SetTLISensitivity(EXTI_TLISENSITIVITY_FALL_ONLY);
EXTI_SetTLISensitivity(EXTI_TLISENSITIVITY_RISE_ONLY);
EXTI_SetTLISensitivity(EXTI_TLISENSITIVITY_BOTH_EDGES);
// Enable interrupts
enableInterrupts();
while (1)
{
// Your main code here
}
}
```
In this example, we configure external interrupt 1 on GPIOC. The interrupt handler function `EXTI1_IRQHandler` is called whenever there is a falling edge on the corresponding pin. You can replace `EXTI1_IRQHandler` with the appropriate interrupt handler for the specific external interrupt you want to use.
Make sure to include the necessary header file for your STM8S microcontroller and adjust the GPIO port and pin for your specific application. Also, don't forget to implement the actual code inside the interrupt handler function to handle the external interrupt event.
Remember to consult the STM8S reference manual and datasheet for more details on configuring and using external interrupts on your specific STM8S microcontroller.
