器件型号:AM2432

您好、TI 专家!

客户正在使用 AM2432、并且已成功使用软件使跳匣区域能够根据以下指南控制 PWM。

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1315129/mcu-plus-sdk-am243x-how-to-configure-sysconfig-epwm-driver-for-trip-zone

基于此、针对 当前的情况、客户希望 通过以下方式触发跳匣区域: GPIO (此为 GPMC0_CSn2/P19)、当这个 GPIO 改变其状态时、它 可能触发跳变区事件、以便控制 PWM。

请问是否可以实现此功能、如果可以、能否提供一些相关指南和演示代码?

非常感谢!
