整体架构是STM32 + CPLD控制2个减速电机带正交编码，3个舵机，8个超声波。一个串口和cubieboard通信，接收下行指令并上传实时监测数据。另一个串口接收遥控器指令。两个都用的DMA方式。(The overall architecture is STM32 + CPLD control 2 deceleration motor with orthogonal coding, 3 steering gear, 8 ultrasonic. A serial port and cubieboard communication, receive the downlink instructions and upload real-time monitoring data. Another serial port receives the instruction of the remote controller. Two ways of using DMA.)
