Hi all, Sorry for referring to a book, but my question is about a powersuppy diagram >from the book "Programming & Customizing the Pic Microconrtoller" by Myke Predko. I've been playing around with the PIC16C54/JW using an 4x20 LCD, and I want to move it from the carrier board I'm using, and want to make my own "small" board. The question I have is in regards to powering this thing. The manual says that the pic I'm using will work from 3.0 - 5.5v, and the book on page 241 shows a diagram of such a power suppy, my question is what is the "7805" indecated in the box? And is it safe to assume that the "Vcc" at the top right does to my PIC? -Kam (^8* =============== Kam Bansal (^8* kamb@jps.net "Save this email in a smaller font to save on disk space"
