步骤
修改 board/Kconfig，添加 adc 相关部分，以下为参考

| menuconfig BSP_USING_ADC
bool "enable ADC"
default n
select RT_USING_ADC
if BSP_USING_ADC
config BSP_USING_ADC1
bool "enable ADC1"
default n
endif
|
如果启用的 adc 不自带，需要手工修改
修改libraries/HAL_Drivers/config/f4/adc_config.h

| scons --menuconfig 启用 adc
stm32XXxx_hal_conf.h 需要启用 HAL_ADC_MODULE_ENABLED
