Hi C'688...
I can't as the real values will eventually be determined by trial and error on the initial build and calibration phases. the V to F relationship is none linear and will range from about 700Hz to 2800Hz; (anywhere in that region depending on the voltage).
As I have pointed out the longhand method works but it is not a lookup table and looks mighty ugly...
Each of the 16 possible values will have its own frequency range as its lookup.

5. How to Post in the The UNIX and Linux Forums
Can please somebody tell me what could be the reason for the following error (Unix Motorola Server):
/usr/etc/ce3/s374: Board at address 0xff10000 not present - Entry skipped.
/dev/lpc2: I/O error
I already replaced the board 374 on the server, but I have the same problem.
Thank you! (1 Reply)

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included.
It needs, so far, two hits at the MIC input with a single hit at the HEADPHONE audio output.
The first at the highest practical resolution for the AC component and the second... (0 Replies)

Apologies for any typos...
For those intersted in the AudioScope the next construction is finished.

Voltage mapping table (if table based mapping)
vsel_reg
Register for selector when using regulator_regmap_X_voltage_
vsel_mask
Mask for register bitfield used for selector
apply_reg
Register for initiate voltage change on the output when using regulator_set_voltage_sel_regmap

Register for control when using regmap set_bypass
bypass_mask
Mask for control when using regmap set_bypass
enable_time
Time taken for initial enable of regulator (in uS).
DESCRIPTION
Each regulator registered with the core is described with a structure of this type and a struct regulator_config. This structure contains
the non-varying parts of the regulator description.
