Developed specifically for programming of PIC 18F2550 micro controllers, this parallel port, no-power, programmer is the smallest of all programmers ever built.
A DB25 Male Connector, one capacitor and a resistor makes this Port Powered programmer.
Programmer takes its power from Parallel Port pins 2-9. VPP for this programmer is 5V and hence "LVP" must be selected in programming software. (See art2003 screen shot Document given below)
I built this programmer to write firmware (boot loader) into my PIC18F2550 which I wanted for my PICKIT2 inspired USB programmer.
A free windows based program called WINPIC800 V.3.59 is available for free download. This software is not intended for this programmer alone, you may use it for many other programmers including few detailed here on this website.
Although, programmer socket is wired for PIC18F250 & 2550, other PICs with similar pin connections may be programmed. You may also wire your own socket for different type of PIC if the same is supported in the WINPIC800 (under Art2003 selection).
