Enter Motor frequency to rotation ratio:
(to7 decimal places). As the PID controller works
on frequency it is necessary to convert the rpm
value into an equivalent frequency. This will be
dependent on the type of motor used and the
pulley size. However, it may be simplified to the
ratio of the frequency to platter rotation speed at
33.3 rpm. Use the formula to work out the ratio:
33.333/Motor frequency (to obtain 33.333 rpm).
For UK: 33.333/50 = 0.66666. For US 33.333/60
= 0.55555

Debug PID to Serial Monitor?
Displays setpoint, output, feedback values to the
serial console. When adjusting the PID values
using the PIDTuning app this parameter will be
set to Y automatically to enable the tuning graph
to work. The rpm indication on the serial monitor
will be temporarily disabled.

3.1.5 Test platter Sensor Trigger
This menu option turns enables/disables an on screen message each time the RPM
sensor is triggered. Primarily used during sensor placement.
3.1.6 RequestedvsProgrammed Values
This is an internal debugging menu which will convert requested frequency values
into the closest values the DDS generator can produce
3.1.7 Write to eeprom
Use this option to save configuration parameters to the internal EEPROM so they are
used when the board is powered up,
3.1.8 Motor ON/OFF
Turns the platter on or off instead of the manual power switch,
