本文件夹中的代码是“GPIO模块”的相应代码。



GPIO_LCM.c 该文件是GPIO模拟时序，实现SPI协议的代码。



GPIO.pdf 该文件是C6713的GPIO连接LED和LCM模块的原理图，至于C6713的其他部分（如SDRAM、FLASH等）和部分控制信号、电源信号都略去。读者朋友可参考另外相关的章节。

-The code in this folder is " GPIO module"　of the corresponding code. GPIO_LCM.c GPIO analog timing of the document is to achieve SPI protocol code. GPIO.pdf the file is the GPIO connection C6713 LED and LCM module schematic, as in other parts of C6713 (such as SDRAM, FLASH, etc.) and some control signals, power signals are omitted. Readers may refer to other relevant chapters.
