/* 1 - D1 blue */
#define LED1_BV BV(0)
#define LED1_SBIT P2_0
#define LED1_DDR P2DIR
#define LED1_POLARITY ACTIVE_LOW
P2_0 设置为驱动LED (蓝灯)
/* set direction for GPIO outputs */ \
LED1_DDR |= LED1_BV; \
LED2_DDR |= LED2_BV; \
GYRO_VDD_DDR |= GYRO_VDD_BV; \
DCDC_DDR |= DCDC_BV; /* Set P0_7 as output */ \
GYRO_VDD_SBIT = 1; /* Gyro must be on for I2C to work */ \
P0DIR |= BV(5); /* Unused pin as output */ \
P2DIR |= 0x01 /* Unused pin as output */ \
P1DIR |= 0xBC; /* UART pins as output */ \
P0INP = 0x4E; /* Tri-state inputs */ \
}
// use this to turn LEDs off during sleep
P2_0 = 1;
HalLedEnterSleep();
P2.0设置为一般I O ，P2SEL=0
无论怎么设置P2_0总是输出低电平 0.4V电压，LED2 P1_7就正常，请哪位帮我指点,谢谢了。
