hello i have a LM13232AFW glcd that have ST7565 controller and i i got PIC16F877A
the porte in the pic could go with the glcd and others too but cant makecode i need those things in for the codeing with c++
comunicate with this LCD Serial or Parall is easyer
how to register the glcd with the pic in the code
i dont need the circet you can make the code with any thing you need

hi
i found a small code by Bascom for HID usb ...
is ther any code for mikropascal to make avr as HID usb?
