您好:
现在用AM5708芯片,配置GPIO6_20中断函数,使用void GPIO_setCallback(uint32_t index, GPIO_CallbackFxn callback)函数,请问index是多少呢?怎么对应的呢?

在AM5708芯片中,GPIO6_20对应的index是144。以下示例代码来配置GPIO6_20中断函数并对应callback函数:
#include <ti/drivers/gpio/GPIO.h> void gpioCallbackFxn(uint_least8_t index) { // Your callback function implementation } int main() { GPIO_init(); GPIO_setCallback(144, gpioCallbackFxn); // Other initialization and code }
在上面的例子中,我们使用了GPIO_setCallback函数来配置GPIO6_20的中断回调函数,并将其对应的index设置为144。然后在main函数中,我们初始化GPIO并将gpioCallbackFxn函数作为回调函数传递给GPIO_setCallback函数。这样当GPIO6_20产生中断时,gpioCallbackFxn函数将被调用。
