i have learnt many things about programmers but never applied it in practice. so i need to program 95080 spi eeprom chip.
the problem is being a complete newbie i'm confused about some of the things. if anyone could help me that would be greatful. i have built many PCBs. but they were usually for light projects and never a programmer. so my basic doubt is that in the base board there is a PIC 18F2550 which according to my logic is used for programming the chips. So i need to program this PIC18F2550 by the provided HEX file. Do i need an external programmer for it or the base board allows to program it as well?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The PIC 18F2550 used in this programmer needs to first be programmed with the HEX file before this programmer will work. It is a chicken and egg problem if you do not know someone with a programmer. I used http://www.lancos.com/prog.html to make a minimum serial programmer to get mine programmed. You can easily do this on a breadboard if you wanted, you just need a computer with a serial port that can run the software.
If you search this forum and read the Openprogrammer web page you can get other ideas on how to get your chip programmed.

The "SI-Prog" works as a JDM if you invert the data out. You can build this in
a bread board and a lot of the components are not needed if you are only going
to use it once. I would not use any components that deal with using power from
the serial port, use the external power options.

This better explains how I programmed my initial 18F2550
Hardware:

Software:
WinPic800

wILL THIS WORK FOR PROGRAMMING THE PIC?
