API

OPCN3

OPCN3(uint8_t pinSelect, uint32_t speedSelect)

The constructor of the OPCN3 class.

uint8_t pinSelect: The number of the ss pin.

uint32_t speedSelect: The speed in Hz (default 500000)

begin()

Setup for the spi connection.

initilize()

Calls begin(). Prints all status information. Turns on Fan and Laser. Sets mode to High Gain. Resets Histogramm.

readDACandPowerStatus()

Returns DACandPowerStatus object.

setFanDigitalPotShutdownState(bool status)

Turns fan on/off.

bool status: If true turns on fan. If false turns fan off.

Returns FanDigitalPotShutdownState object.

setLaserDigitalPotShutdownState(bool status)

Turns laser on/off.

bool status: If true turns on laser. If false turns laser off.

Returns LaserDigitalPotShutdownState object.

LaserPowerSwitchState(bool status)

TODO

setHighLowGainState(bool status)

Turns laser on/off.

bool status: If true set high gain. If false set low gain.

Returns HighLowGainState object.

readHistogramData()

Returns HistogramData object.

readSerialNumber()

Returns SerialNumber object.

readConfigurationVariables()

Returns ConfigurationVariables object.

resetHistogram()

Resets the histogram.

Returns a bool which indicates, if the reset was successfully.
