已经有人可以成功跟d2c的port通信同步了。据说"according to phonymike the d2c proccesors pullup (3.3v) is so weak you dont need to do anything ..you just throw code at it." "As long as we keep any code sent to it, then the port stays open, when the code is interrupted then it closes "
他们的信条是
Code should be free and hardware should be cheap!
软件应该免费,硬件应该便宜!
