 The ADS1100 consists of a delta-sigma A/D converter core with adjustable gain, a clock generator, and an I2C interface.

 ADS1100 itself is able to accept a differential input from -5 ~ +5 V, but we have limited the input to 0~12V by adding on the peripheral circuit design of this IC.

 ## 描述
 
 **BugC**是一款兼容M5StickC的可编程机器人底座，底座主要部分由四路电机驱动器、四路直流电机、控制芯片为STM32F030F4、2个可编程RGB LED以及电池座和独立开关等部件组成，外观小巧运动灵活.
-Bugc底座需要结合M5StickC控制器使用.在底座上，配备了四个由STM32F030驱动的直流减速电机，电路连接至M5StickC的顶部插槽，通过I2C协议通信，最终实现控制.
