Hello. Forgive me if I seem stupid to this topic. I have been interested in Pic's for some time now and never until today managed to actually find time to look into them further. I have been interested in Dallas Semi 1 wire network stuff and consequently temperature logging, humidity and rainfall etc using the Pc serial port. I find it annoying though that the computer has to be on and most of the time idle just to be able to monitor temperature etc. My aim is to develop a logger of some sort using the pic 16f84 and maybe either Dallas 18b/s20 or DS1621. I am not worried about current temperature display although that would be nice, but more of a Min / Max temperature and time interval temperature, so I can connect to the serial port after a period of time say overnight and download the raw data. Like I say I am very new to Pic's but very keen to start. Please let me know any ideas, projects, source or in fact absolutely anything that would help me make this a success. Thanks in advance for your help Paul Tyrer. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
