All I can tell you is that the book they sell Experimenting with PicBasic Pro compiler uses 16F877 and 876 as well as 84's so I'd assume the compiler must cover these. I've always had good service form Crownhill, I buy most of my Pic's from them, and even when they charge me VAT by mistake it gets rectified quite quickly. This might help from their website - "The PicBasic Pro Compiler is a DOS command line application (it also works in Windows) and runs on PC compatibles. It can create programs for the PIC12C67x, PIC12CE67x, PIC14C000, PIC16C55x, 6xx, 7xx, 84, 92x, PIC16CE62x, PIC16F62x, 8x, 87x, PIC17Cxxx and PIC18Cxxx microcontrollers and works with most PICmicro programmers, including our EPIC Plus Pocket PICmicro Programmer. A printed manual and sample programs are included to get you started." You too can find this at http://www.picbasic.co.uk/item2.htm >From this page you can also download the PicBasic Pro instruction set and the manual . Now Mr Crownhill and Co a coupla 18F252's would be nice for that advert -:) Colin -- cdb, bodgy1@optusnet.com.au on 21/02/2003 I have always been a few Dendrites short of an Axon and believe me it shows.
