Dear all, I have just posted my PIC assembler for unix to ftp.funet.fi called pictools.tgz and pictools.info (I hope). This will no doubt be moved under the /pub/microprocs/pic heirarchy soon. I has been written using gcc (ANSI C) under Linux, but should be very portable! It is version 0.1 and may/will have bugs so don't just trust it on OTP parts until you simulate (you mean you don't already) and use EPROM/EEPROM parts for first prototypes! Anyway hope you like it =%-) Ian p.s. If it does not appear in a couple of days I will try again p.p.s. If you really can't wait or don't have ftp access then I could e-mail it to you (~40k bytes uuencoded), but the number of people who I could do this for is limited!
