Methods

ChannelRegister(byte)

Returns the first of a channel's four consecutive registers.

public static byte ChannelRegister(byte channel)

Parameters

channel byte

The channel, 0 to 15.

Returns

byte

The register address.

Exceptions

PamojaException

The channel is beyond the part.

FrequencyForPrescale(byte, uint)

Returns the update rate a prescale value produces.

public static float FrequencyForPrescale(byte prescale, uint oscHz = 25000000)

Parameters

prescale byte

The prescale register value.

oscHz uint

The oscillator frequency, usually InternalOscHz.

Returns

float

The frequency in hertz.

PrescaleForFrequency(uint, uint)

Returns the prescale value that sets an update rate.

public static byte PrescaleForFrequency(uint updateRateHz, uint oscHz = 25000000)

Parameters

updateRateHz uint

The PWM frequency wanted.

oscHz uint

The oscillator frequency, usually InternalOscHz.

Returns

byte

The prescale register value.
