您好！
我尝试在 CC2650MODA 中使用 ADC。 我正在使用 cc2650MODA 中的引脚 IOID 9来获取值。 我将在 IOID 9引脚上应用1.65v、我得到的 ADC 值为4。
我已经修改了电路板。 用于配置 IOID 9引脚的 H 和 CC2650Launchxl.c 文件。 但我无法获取正确的值。
修改 CC2650Launchxl.c 文件、

对 CC2650Launchxl.h 文件进行了修改
#define Board_DIO07_ANALOG PIN_DESIGNODED
#define Board_DIO08_analog PIN_Unassigned
#define Board_DIO09_ANALOG IOID_9
#define Board_DIO10_ANALOG PIN_DESIGNODED
#define Board_DIO11_ANALOG PIN_DELOADD
#define Board_DIO12_ANALOG PIN_DESIGNODED
#define Board_DIO13_ANALOG PIN_DELOADD
#define Board_DIO14_ANALOG PIN_DESIGNODED
对 Board.h 文件进行了修改
#define Board_ADC0 CC2650_LAUNCHXL_ADC2
问题可能出在哪？
