4.3.4 - Analog Outputs [U3 Datasheet]

The IOType to set the voltage on an analog output is:


The following are IOTypes used to write/read the enable bit for DAC1:

LJ_ioPUT_DAC_ENABLE  //Ignored on hardware rev 1.30+, as DAC1 always enabled.

The following is a special channel, used with the get/put config IOTypes, to configure a parameter that applies to all DACs:

LJ_chDAC_BINARY  //If set nonzero put_dac values should be 0-65535.

Following is example pseudocode to set DAC0 to 2.5 volts:

//Set DAC0 to 2.5 volts.
ePut (lngHandle, LJ_ioPUT_DAC, 0, 2.50, 0);
