單片機源程序如下:

//******************************************************************************
// Author:wwj
// Built with IAR V7.0
// Gui Lin
// IDE IAR430
/*截止當前：
功能：
本程序從平衡車程序移植出來，仍有平衡車的影子，但不影響運行。
1.硬件IIC讀取6050，并在OLED上顯示
2.中斷測速
3.pwm電機驅動
4.循跡（由于每個人裝循跡模塊的位置都會有差異，需要自己調整傳感器）
5.按鍵檢測
6.藍牙控制
7....ADD ING
勿拿本代碼做交易！！！
勿拿本代碼做交易！！！
勿拿本代碼做交易！！！
本來只想放出來演示，突然發現有人從中謀取利益，于是決定共享源碼！!!
各位朋友加油，未來的科技看你們！！！
