How I can read calibration data in ATMEL

[luben111]

Hello,

Does anybody knows is it possible to read the calibration data in ATMEL?

best regards

if you want to read calibration bytes from AVR try it

hxxp://elm-chan.org/works/avrx/report_e.html


but you needed set calibration register in your application .

do you reading chip signature?[/list]

I know that standard way - with the programmer you read the calibration data and then you can write it into rpogram memory. Then , after I program the chip and run it I can take this value and set it into calibration register.

The problem is that I have 10 000 already programmed and mounted AVR devices, that have to reprogrammed..

If I can read directly from the program the calibration bit, then I can just don't need to read in the programmer this value and then to write it in the memory... I need direct way to read the calibration data (like is in Microchip)
