蓝牙小车的程序可以根据不同的微控制器和开发环境编写。以下是基于51单片机和STM32的蓝牙小车程序示例:
基于51单片机的蓝牙小车程序
```c
include include <蓝牙.h> define uchar unsigned char define uint unsigned int sbit IN1 = P2^4; sbit IN2 = P2^5; sbit IN3 = P2^6; sbit IN4 = P2^7; sbit ENA = P2^0; sbit ENB = P2^5; uint bht; uint bht_mode = 0; uint forward = 0; uint backward = 0; uint left = 0; uint right = 0; uint stop = 0; void init() { TMOD = 0x01; // 定时器0工作模式1 TH0 = 0xFF; TL0 = 0xA3; ET0 = 1; // 定时器0中断使能 TR0 = 1; // 定时器0启动 } void time0() interrupt 1 { TH0 = 0xFF; TL0 = 0xA3; numl++; num2++; if (numl == 100) { numl = 0; if (num2 == 100) { num2 = 0; if (bht_mode == 0) { forward = !forward; } else if (bht_mode == 1) { backward = !backward; } if (forward) { left = 1; right = 0; } else if (backward) { left = 0; right = 1; } else { left = 0; right = 0; } ENA = 1 - ENA; } } } void main() { init(); while (1) { if (bht_mode == 0) { if (left) { IN1 = 1; IN2 = 0; } else if (right) { IN1 = 0; IN2 = 1; } else { IN1 = 0; IN2 = 0; } } else if (bht_mode == 1) { if (left) { IN1 = 1; IN2 = 1; } else if (right) { IN1 = 0; IN2 = 0; } else { IN1 = 0; IN2 = 0; } } else { IN1 = 0; IN2 = 0; } } } ``` 基于STM32的蓝牙小车程序
