LabJack U3-HV Test
Posted: Thu Nov 17, 2011 8:43 pmThis is a simple test example of how to set up the LabJack U3-HV DAQ system.
The I/O is a set of strings starting "DI", "DO" or "AI" for digital in, out and analogue in respectively. After that there's a number to identify the pin. In the case of analogue it defaults to single ended but you can set the neg. channel with a minus symbol followed by "SE","SP","VR" or the number of the pin you want to have as the neg. channel.
The timer string is in the form {number of timers} {clock{/divisor}} {mode timer0} {value timer0} {{mode timer1} {value timer1}}
Modes are strings and map onto your modes exactly so can be one of the following PWM16, PWM8, RISINGEDGES32, FALLINGEDGES32, DUTYCYCLE, FIRMCOUNTER, FIRMCOUNTERDEBOUNCE, FREQOUT, QUAD, TIMERSTOP, SYSTIMERLOW, SYSTIMERHIGH, SYSTIMERHIGH, RISINGEDGES16 or FALLINGEDGES16.
