 # Unit ADC
 
-## DESCRIPTION
+## 描述 DESCRIPTION
 
-This is a unit having self-calibrating function and 16bit analog-to-digitial coverter. The resolution is double than insided ADC of esp32, that means you can detect smaller amplitude voltage. The unit communicates with M5Core with I2C. It has provided two modes: continuously conversion and single conversion.
+这是带自校准功能的16位模拟数字转换unit，相比ESP32芯片自带的ADC（12位）功能分辨率高了不少，意味着你可以测量更小幅值的电压等模拟量，也就是能测量更细微一倍的模拟量，比如采集心电电压做心电监护项目、做血压监测项目、高精度电压监控项目等等。unit集成的ADC芯片通过I2C接口与M5的主控通讯，可以设置成单周期转换和连续转换方式。
 
-## FEATURES
+## 特性 FEATURES
 
--  Up to 16 bits of resolution and perform conversions at rates of 8, 16, 32, or 128 samples per second
--  Programmable gain amplifier
-    - Gain = 1, 2, 4, OR 8
--  Detect 0~12V voltage Input
--  Two Lego installation holes

-这是带自校准功能的16位模拟数字转换unit，相比ESP32芯片自带的ADC（12位）功能分辨率高了不少，意味着你可以测量更小幅值的电压等模拟量，也就是能测量更细微一倍的模拟量，比如采集心电电压做心电监护项目、做血压监测项目、高精度电压监控项目等等。unit集成的ADC芯片通过I2C接口与M5的主控通讯，可以设置成单周期转换和连续转换方式。
-
-## 特性 FEATURES
-
--  ADC有16位分辨率，可以设置每秒采样8、16、32、128次以进行A/D转换
--  ADC芯片内部可以产生高达8倍的放大，从而可以采集幅值更小的模拟信号
--  能测量0~12V的电压输入
--  乐高孔接口
-
-## 应用 APPLICATION
-
--  心电信号采集
--  血压测量
--  测力计

-## 描述 DESCRIPTION
-
-这是带EEPROM存储的12位数字模拟转换unit，相比ESP32芯片自带的DAC（8位）功能分辨率高了不少，可以将输入的数字信号转换成模拟信号如电压、声音等输出。unit集成的DAC芯片是单通道采集，通过I2C接口与M5的主控通讯，你还可以将输入端的数字量和配置数据都保存到EEPROM中，这样在上电之后，能够立马将本来保存的数字量转换成模拟信号输出。
