AFE20408 第 1 页包含 ADC 配置寄存器。此文件包含寄存器和特定数据组合的相关变量。在对此页面上的任何寄存器进行写入或读取之前，您需要将 0x0001 写入 PAGE 寄存器。

此页面包含以下寄存器：

示例：

    #Example: Configure ADC
    ftdiObject.spiWrite(PAGE_ADDRESS, PAGE_ADC_CONFIG)  #Set ADC page

    #Set the following parameters:
        #ADC False Alarm = 16
        #Sense False Alarm = 32
        #Temp False Alarm = 4
        #ADC in automode
        #Shunt range 163.84mV
    ftdiObject.spiWrite(ADC_GEN_CFG_ADDRESS, ADC_GEN_CFG_FALR_ADC_16 + ADC_GEN_CFG_FALR_SENSE_32 + ADC_GEN_CFG_FALR_TMP_4 + ADC_GEN_CFG_AUTOMODE_Automode + ADC_GEN_CFG_SHUNT_RANGE_163p84mVrange)
    #Set the following parameters in the ADC_CONV_CFG_0 register:
        #ADC Conversion rate = 152us
        #SENSE Conversion rate = 282us
        #Temperature conversion rate = 4122us
    ftdiObject.spiWrite(ADC_CONV_CFG_0_ADDRESS, ADC_CONV_CFG_0_CONV_RATE_ADC_152us + ADC_CONV_CFG_0_CONV_RATE_SENSE_282us + ADC_CONV_CFG_0_CONV_RATE_TMP_4122us)
    #Set the following parameters in the ADC_CONV_CFG_1 register:
        #ADC Samples = 16
        #SENSE Samples = 4
        #Temperature Samples = 1
    ftdiObject.spiWrite(ADC_CONV_CFG_1_ADDRESS, ADC_CONV_CFG_1_AVG_ADC_16samples + ADC_CONV_CFG_1_AVG_SENSE_4samples + ADC_CONV_CFG_1_AVG_TMP_1sample)
