摘要
为激发学生学习兴趣,在单片机教学中采用项目教学法,以具有趣味性的凌阳语音控制小车作为开发平台,完成了小车的基本功能、调速功能和语音识别功能,并在此基础上进行二次开发,即采用nRF2401无线模块传输语音命令,减小了小车电机噪声的影响,增大了语音控制距离;采用SYN6288中文语音合成模块扩展了小车的语音输出功能。教学内容由易到难,包括单片机及其外围电路硬件和软件的设计,教学过程循序渐进,不仅提高了学生应用单片机的能力,而且培养了学生的创新意识。
The method of project teaching is used to stimulate students＇ interest in microcontroller teach- ing. Sunplus voice control car was used as the development platform. It was completed with basic func- tion, speed control function and voice recognition function. Then, the add-on functions were developed. The wireless module nRF2401 was used to transmit voice commands. The influence of motor noise was re- duced and the distance of voice control was increased. The Chinese speech synthesis module SYN6288 was used to extend the voice output function. The teaching content was designed from easy to difficult. It involved the hardware and software design of microcontroller and its peripheral circuit. The teaching process was designed step by step. These not only improved students＇ ability of microcontroller applica- tion,but also trained students＇ consciousness of innovation.
