Hi, all Thanks to all who helped me with finding compilers last week. I didnt find any strictly basic compilers, but a few which are similar and may be good for my purposes. I have a couple more questions if someone has time to give an answer. I have several assemblers, and I've seen several more in my net browsing. I am ready to start studying one, but I would like to know if any particular ones are considered better than others. The type of mnemonics is of no concern since the only types I had experience with are ancient 8080, 6502,6800 and such. I have the ITU pic 1 programmer, and most of their software, and now I need to buy some pics. Im confused by the plethora of chips available and after studying their selector guides and looking in catalogs, I still have some questions. Some eeprom pics are "flash" and others just eeprom. Whats the dif? 16c84 versus 16f84? Is there a good faq which deciphers the family of chips ? Thanks for any input. Don email is bjmcpher@usit.net
