I am having weirdness from a a pic 16f877 running at 32khz. It refuses to operate the a/d on anything except internal oscillator, and the readings are haywire. I got the code sorted, and had one here giving believeable readings (I'm only using one channel, and can check the sense of a reading handily).
It's reading temprature & displaying it. In every 10 seconds, it reads on 7.5, 8.5, & 9.5 secs, and displays the result (of the 7.5 sec reading) on 8 secs, and the result of the 8.5 sec reading on 9 secs. It went out perfect - reading well, and freezing when I froze the temprature sensor, going up when I heated it. Now it's staying on 15 degrees whatever the temprature :-o. Another one doubles the reading, (7 degrees, 15 degrees) which bears no relation to the input. The input, & reference voltage, are stable & correct. I have pics on order, but has anyone had problems with this frequency? -- Regards, Declan Moriarty. -- Author: Declan Moriarty INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
