在常用画线算法的基础上,提出了一种利用定点数在点阵液晶屏上进行坐标修正的方法,并利用

DSP实现,该方案能弥补单片机在高速数据处理上的不足.以TMS320VC5402及内置控制芯片SED1335的

液晶屏为例,说明其接口电路和软件实现.

-MCU could not complete the high-speed data processing, so the amendment of painting algo-

rithm was achieved by using a fixed-point DSP in the dot-matrix LCD screen. TMS320VC5402 and the

LCD built-in chip SED1335 were used to illustrate its interface circuit and software
