View Full Version : Gathering chip temperature from PIC18F26K83

I have an application where I'd like to gather approximate internal chip temperature from a PIC 18F26K83. From the datasheet this requires looking up calibration data stored on the processor as part of the process. That data appears to be stored in a thing called the Device Information Area (DIA) not in specific readily accessible registers. So, my question is: to gather that data, do I use a PEEK command and use the relevant address listed in the datasheet table at the address used for the Peek statement?

Thanks,

Troy

it looks to be pretty much the same as for any of the non volatile memory for that chip


10004



once region is set


10005

Okay, thanks Richard. I was really hoping to avoid assembly, but it is what it is.

Thanks again for that Richard. I'm discovering the only assembly instruction I really need as an assembly call is the table read command. Everything else (reading & writing to registers) can be done in Pic Basic.

Cheers,

Troy
