CALIBRATEOFFSET

[Kiyoshi Iwai]

Hello,

I would like to know the CALIBRATEOFFSET function in detail.

Could you disclose the part of source code on this CALIBRATEOFFSET function?

Best regards,

Hi,

CALIBRATEOFFSET is a hardware feature, not a software function. The SAADC will sample the input and use an algotithm to find the offset value. The offset value will be stored in the peripheral and used to compensate the offset error. It is recommended to run calibration at least once, and on major temperature changes, as described in the documentation.

Best regards,
Jørgen

Hello Jørgen,

Thank you for reply.

Can I read the offset value stored in the peripheral? Where can I get it?

Thanks,

Hi,

The offset value is internal and can not be read by the application.

Best regards,
