i have the EPIC programmer and a Parallax LCD. i'll want to program a mcu to display some text onto the lcd. question, the lcd has a 3-pin header and the EPIC has a 10-pin header. is there such a thing as a 3-to-10 pin header cable to connect the two? or do i get the lcd connected to a breadboard?

new to the mcu world so hang with me here...

The 10 pin header you have on the EPIC is used to program PIC microcontroller in circuit. refer to the following link
http://melabs.com/support/icsp.htm

If your LCD have a 3 pin header, it's high likely a serial type. So you may need to use HSEROUT/DEBUG/SEROUT or SEROUT2 to display some text on your LCD.

Your LCD datasheet should show the pinout of your LCD. I would bet on the following model

Your EPIC will be connected to your PIC microcontroller to program it, your PIC will be connected to your LCD all the time.

thanks Steve

I have those docs dl'd and going over them.

let me make sure i understand this. with the PIC16f88 in the EPIC, then i can connect the LCD to the Vdd & Vss pins on the PIC via test leads and send char's to it via the PIC?
