For this project I am using the PICmicro MCU C Compiler. It can also be used with MPASM a BASIC compiler or a number of other C compilers. The EPIC Plus Programmer can be powered with two 9-volt batteries or an optional AC adapter recommended . The EPIC Plus Programmer connects to a PC compatible parallel printer port and includes an assembler and programming software. It is available either assembled or as a bare board. Software Installation The EPIC Plus Programmer files are compressed into a self-extracting file on the disk. They must be uncompressed before use. To uncom 138 Chapter 7 Programming the PIC16F876 Microcontroller press the files first create a directory on your hard drive called EPIC or another name of your choosing by typing c md epic at the DOS prompt. Change to this directory cd epic Assuming the distribution diskette is in drive a uncompress the files into the EPIC subdirectory a epic2xx -d where epic2xx is the name of the self-extracting file on the diskette. Don t forget the -d option on the end of the command. This ensures that the proper subdirectories within EPIC are created. Alternatively can be run to perform similar steps. If the EPIC directory already exists you will get an error message and the installation will continue. Hardware Installation Make sure there are no PICmicro MCUs installed in the EPIC programming socket or any connected adapter s socket until the programming software is executed and the light-emitting diode LED is off. Also be sure that the EPIC Plus Programmer is placed on an insulated surface to prevent the shorting out of traces on the bottom. Connect the EPIC Plus Programmer to a PC compatible parallel printer port using a 25-pin male to 25-pin female printer extension cable. The EPIC Plus Programmer uses pins 2-6 10 and 19-25. A serial cable may not have all of .
