摘要
对TMS320F2812型数字信号处理器的硬件资源和相应的外部设备进行了详细的介绍,分析了19264液晶显示器的接口电路、控制系统,以及按键的结构.在此基础之上,利用TMS320F2812型数字信号处理器的GPIO口对按键电路和液晶接口电路进行了设计,通过调试和仿真后发现本方案可行.
The hardware resource and corresponding peripherals of TMS320F2812 DSP are introduced, the interface circuits as well as the control system and press-key structure of the 19264 LCD device are discussed. Based on these factors, the GPIO ports on TMS320F2812 are used to design press-key and LCD interface circuits. Testing and simulation show that this design is workable.
