用是ADC1_IN8 GPIO1_IO08,在文件里i.MX_Linux_Reference_Manual.pdf

• ADC1_IN0: Analog channel 1 input 0
• ADC1_IN1: Analog channel 1 input 1

• ADC1_IN2: Analog channel 1 input 2
• ADC1_IN3: Analog channel 1 input 3
• ADC2_IN0: Analog channel 2 input 0
• ADC2_IN1: Analog channel 2 input 1
• ADC2_IN2: Analog channel 2 input 2
• ADC2_IN3: Analog channel 2 input 3

只有8路,编程接口

/sys/devices/soc0/soc.1/2200000.aips-bus/2280000.adc/iio:device0:
/sys/devices/soc0/soc.1/2200000.aips-bus/2284000.adc/iio:device1:

不知该如何设置配置?
