TI-RTOS示例程序 gpiointerrupt_MSP_EXP430FR5994_TI 主函数中 GPIO_write(Board_LED0, Board_LED_ON) 函数是让P1.0输出高电平，但是Board_LED0 是怎么映射到P1.0的？ 追踪其定义可以知道其映射到了下面这个结构体中的 MSP_EXP430FR5994_LED1
typedef enum MSP_EXP430FR5994_GPIOName {
MSP_EXP430FR5994_S1 = 0,
MSP_EXP430FR5994_S2,
MSP_EXP430FR5994_LED1,
MSP_EXP430FR5994_LED2,
MSP_EXP430FR5994_S1 = 0,
MSP_EXP430FR5994_S2,
MSP_EXP430FR5994_LED1,
MSP_EXP430FR5994_LED2,
MSP_EXP430FR5994_GPIOCOUNT
