摘要：该声音导引系统由声音导引主控系统和小车控制系统两部分组成。声音导引主控系统主要由主控MCU、声音接收部分、无线发射模块组成。小车控制系统主要由MCU、固化模块NEC、电机驱动部分、声光部分及无线接收模块组成。该系统的最大特点在于其软件设计使用层次化、模块化设计方法，系统低功耗，性价比低。经调试和测试，系统各项性能参数达到设计指标。 关键词：声音导引、无线收发、声源移动、M 智能语音小车-Abstract: The guidance system consists of the sound systems and car audio guidance master control system composed of two parts. Sound-guided mainly by the main control system master MCU, the sound receiving part, the wireless transmitter module component. Vehicle control system mainly consists of MCU, curing module NEC, motor drive parts, sound and light parts and the wireless receiver module. The most prominent feature of the system software designed for use in its hierarchical, modular design approach, the system low-power, low cost. The debugging and testing, system performance parameters to achieve the design target. Key words: sound guidance, wireless transceiver, a sound source movement, MCU, NEC, motor drive

STM32平台下，DS18B20温度传感器驱动。方便移植，用到一个定时器用于us延时。

这是一个1200波特的FSK调制解调器的源代码，并创建了代码中的基于PWM正弦波发生器使用的AVR库。我用ATMEL ATMEGA2313微控制器和从PWM输出引脚ATMEGA2313，我产生一个PWM信号。PWM信号是DDS的形式（直接数字合成），所以如果您的PWM输出连接到一个简单的低通滤波器就可以达到很好的正弦波。它的测试和应用代码。祝好运。
