基于单片机X-Y绘图仪程序，可以画三角形，直线和圆形。-Microcontroller-based XY plotter program, you can draw a triangle, linear and circular.

XY平面绘图仪，由单片机外接键盘输入信号，C52单片机输出控制信号，经过两个细分驱动器驱动X、Y两个电机移动完成图形绘制。单片机采用逐点比较法插补算法完成直线和圆弧的绘制，通过直线和圆弧的组合完成图形的绘制，最终实现了画线、画圆弧、画矩形、甚至可以实现复杂的图形绘制。(The XY planar plotter is input from MCU to keyboard. Output signal is controlled by C52 microcontroller. After two
