Hi,
This is taken from the user manual of cc112x:
"Fast frequency hopping without calibration for each hop can be done by performing the necessary
calibration at start-up and saving the resulting FS_CHP, FS_VCO4, and FS_VCO2 register values in
MCU memory. Between each frequency hop, the calibration process can then be replaced by writing
the calibration values that corresponds to the next RF frequency."
My question is if this also applies to the errata regarding manual calibration. Can one read back the register values after manual calibration of each RF frequency channel (at start-up), and then write the corresponding registers after changing frequency? Or is it mandatory to do manual calibration after each frequency change?
I understand that if the ambient temperature has changed since start-up, the table must be updated. But let's say the temperature does not change much.
And if the temperature changes, how great is the change in temperature that would require the application to update the calibration register values?
Regards
Hans Christian
