TI中文支持网Part Number:AM5708
我想在AM5708 DSP核 实现按键的轮训和按键中断功能，参考SDK的代码配置，但是功能没法实现，不清楚是不是驱动没配置好。
如下代码现象：LED输出翻转正常，两个按键检测都不工作。
/**
* \filetl-led-flash.c
*
* \briefExample application main file. This application will toggle the led.
*The led toggling will be done inside an callback function, which
*will be called by Interrupt Service Routine. Interrupts are
*triggered manually and no external source is used to trigger
*interrupts.
*
* \version 1.0

您好，
Zaki 说：如下代码现象：LED输出翻转正常，两个按键检测都不工作。
能否分享更多信息？您这里指的按键检测是什么？
