Hi,

I am new to labjack and python and am having some trouble finding the code to control outputting voltage through the analog outputs that aren't DAC. To control the DAC outputs, I'm using

 

DAC0_VALUE = d.voltageToDACBits(1.2, dacNumber = 1, is16Bits = False)
d.getFeedback(u3.DAC0_8(DAC0_VALUE))
 
this sets the DAC0 to 1.2 volts.
How can I do something similar for the FIO outputs?
 
Thanks for your help

The U3 only has the 2 DAC lines for analog outputs. The FIO and EIO lines are flexible and can be set to analog inputs or digital I/O lines. Digital I/O lines read or set a high or low state. A low state is about 0.0 V and high is 3.3 V. FIO line usage is demonstrated here in the quickstart:

If you need more analog outputs, there is the LJTick-DAC which provides 2 additional analog outputs through 2 digital lines.
