do you guys have a MikroC code for interfacing these two components? needed it badly! thanks. i'm really having a hard time initializing the 3310 to the PIC
3310 communicates using fbus protocol, which is more or less 100 bytes depending on the message, therefore it would be difficult with PIC16F877A because of banking and paging, use PIC18F instead.
Use phones with modem (supports AT commands) if 877A is to be used.
