摘要
为了解决嵌入式控制系统CSTN-LCD屏幕图形打印不便的问题,利用AT89S52单片机控制CPLD截取CSTN-LCD屏幕显示数据,存放到RAM中,并通过单片机的串口或USB接口将RAM中的数据传送到PC,在PC上将所截取的数据转换成BMP格式图像文件,实现了CSTN-LCD屏幕图像在PC上的显示、存储以及灵活输出。
In order to solve the problem which is inconvenience of printing the graphic that is displayed on the embedded control system＇s CSTN-LCD screen. The data which displayed on CSTN-LCD are intercepted by CPLD under controlling of AT89S,52 （MCU） and stored in RAM. The data in RAM are transmitted to PC through serial port of the MCU or USB and formed to BMP format file in PC. So the screen picture of the CSTN-LCD can be displayed or stored in PC and flexible export.
