您好！

请参考工程：GR551x_SDK_V1.7.0\projects\peripheral_app\adc\app_adc，加入

1. GR551x_SDK_V1.7.0\components\drivers_ext\gr551x\gr551x_vbat_api.c

2. GR551x_SDK_V1.7.0\components\drivers_ext\gr551x\gr551x_adc_voltage_api.c

部分相关代码如下：

#include "gr551x_temp_api.h"
#include "gr551x_vbat_api.h"


		hal_gr551x_temp_init();
		double temp = hal_gr551x_temp_read();
		printf("current temp: %f degrees\n", temp);
		
		hal_gr551x_vbat_init();
		double vbat = hal_gr551x_vbat_read();
		printf("current vbat: %f v\n", vbat);
