By setting a proper pattern in the input data pins, you could obtain the read of IC internal temperature (on output pins). I don't know anymore. Is there something true? Posted By MagerValp on 2002-12-16  cbm-hackers This was discussed a while back on cbm-hackers. It has to do with the built in I/O port at $0000/01, and I think it only works on the HMOS (85xx) chips. You can't really tell the temperature, but the characteristics will change depending on temperature. You'd have to calibrate the software for your particular CPU for it to work. Posted By SVS on 2002-12-16  85xx could include... 8501? :) and furthermore, what are the exact data to be read/write to? Thx Back to top Reply to this topic Copyright © Plus/4 World Team, 2001-2025.
