28388 P0 Linkstatus and Link Active LED

Other Parts Discussed in Thread: C2000WARE

          请问GPIO148和GPIO143是由谁进行控制的?是ESC芯片自己吗?为什么例程中将两个引脚配置为输入,可是例程中并没有对这两个引脚进行控制。           

GPIO_setPinConfig(GPIO_148_ECAT_PHY0_LINKSTATUS);
GPIO_setPadConfig(148, GPIO_PIN_TYPE_STD);
GPIO_setPinConfig(GPIO_143_ECAT_LED_LINK0_ACTIVE);
GPIO_setQualificationMode(143, GPIO_QUAL_ASYNC);
GPIO_setPadConfig(143, GPIO_PIN_TYPE_INVERT);
