I seem to be havving trouble with this routine http://www.piclist.com/techref/microchip/math/radix/b2a-24b9d-lzmsdp-tk.htm My version (text edited, not code) http://home.clear.net.nz/pages/joecolquitt/24-ascii.html AFAICS they're the same s/w The problem is that the conversion never finishes and loops endlessly. I wonder if anyone who has got a working version of this (maybe one of the authors) can verify that it does work as presented and/or can spot a mistake on my part TIA -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
