STM32单片机的桌面宠物机器人（基于HAL库）

效果

基于STM32单片机的桌面宠物机器人

概要

语音模块：ASR PRO，通过天问block软件烧录语音指令

主控芯片：STM32F103C8T6 使用HAL库

屏幕：0.96寸OLED屏，用来显示表情

4个舵机，用来当作四只腿

底部一个面包板

分析

初始化代码，使用TIM3定时器的四个通道输出PWM驱动舵机，控制腿部的运动

cpp 复制代码

    HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_1);
    HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_2);
    HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_3);
    HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_4);

    OLED_Init();
    OLED_Clear();
    OLED_ShowImage(0, 0, 128, 64, BMP1);
    mode_stand();

ASR PRO获取到语音后通过串口通信把数据发送到STM32，在单片机内使用中断的方式获取语音数据,，然后根据语音指令判断当前的动作

cpp 复制代码

    while (1) {
        HAL_UART_Receive_IT(&huart1, &command, 1);
        if (command == 0x32) {  // 前进
            mode_forward();
        } else if (command == 0x31) {
            mode_slowstand();
        } else if (command == 0x33) {  // 后退
            mode_behind();
        } else if (command == 0x34) {  // 左转
            mode_left();
        } else if (command == 0x35) {  // 右转
            mode_right();
        } else if (command == 0x36) {  // 前后摇摆
            mode_swing_qianhou();
        } else if (command == 0x37) {  // 左右摇摆
            mode_swing_zuoyou();
        } else if (command == 0x38) {  // 跳舞
            mode_dance();
        } else if (command == 0x39) {  // 立正
            mode_stand();
        } else if (command == 0x41) {  // 起身
            mode_slowstand();
        } else if (command == 0x61) {  // 坐下
            mode_strech();
        } else if (command == 0x63) {  // 伸懒腰
            mode_lanyao();
        } else if (command == 0x64) {  // 抬头
            mode_headup();
        } else if (command == 0x65) {  // 趴下睡觉
            mode_sleeppa();
        } else if (command == 0x66) {  // 卧下睡觉
            mode_sleepwo();
        } else if (command == 0x68) {  // 睡觉
            mode_sleepwo();
        }
        /* USER CODE END WHILE */

        /* USER CODE BEGIN 3 */
    }
