小弟依照别的人程序改造了一个PS/2鼠标的接口程序，用Codevision写的，用的MCU是Tiny2313，PA0和PA1接鼠标的数据线和时钟线，PB口接上8粒LED灯，用来显示接收来鼠标发送过来的数据。我和程序默认显示的是第一个字节数据。这个程序有时会有点问题，不知道怎么搞的，如果我显示的第二或第三，或第四字节，有时自己会变成第一字节，呵呵，可能是一个BUG吧。还有一个问题是，听别人说这个程序会挑鼠标，如果能和一个鼠标通讯，换成另一种鼠标就无法通讯。估计是mouse_send()这个函数有点问题，导致在鼠标初始化时无法进入3D滚轮模式（4BYTE），而只能工作在2D模式（3BYTE），而主程序里却在按3D的模式来接收数据。请大家来改进。 -Brother in accordance with the other one program to a ps 2 the interface program codevision, the mcu s tiny2313 pa0 pa1, and then the data and the clock line to the pb to 8 of the light, led to display received to the sending of data and programs. i acknowledge that is the first byte data. this process can sometimes be something wrong, don t know what s wrong　if i shows the second or third or fourth byte, and sometimes she would become the first byte, this maybe is a bug. Another problem is, to say that this process will choose the mouse, and a mouse to the other communications, a mouse can t communicate. maybe the mouse enormous send () this function is a little problem in the initializing unable to enter the 3d wheel mode （ 4byte ）, but we can work in 2d mode （ 3byte ）, and in the main program in a 3d patterns to receive the data. i ask everyone to improve.
