个人开发小程序，用proteus7.9仿真，控制芯片用microchip生产的PIC24系列，采用两片DSP之间SPI通讯方式，主机DSP发送数据，从机DSP接收到数据并在液晶上显示，反过来通信也一样。开发环境IDE环境mplab 8.76,proteus 7.9,液晶LM016L，想学SPI全双工通信的可以看一下-Personal development of small procedures, using proteus7.9 simulation, control chip product

few ways of connecting Graphics LCD System to PIC24 devices.
