Parameters
DAC# Identifies which DAC channel is to be read
• can be DAC1 or DAC2
Variable The variable that hold the desired output voltage
• The scale is 0-32767 = 0.0 to 10.0 volts.
Returns
0 – Setup did not execute.
1 – Setup successful.
Error Codes
Bad_ID = an incorrect DAC ID was used.
PT_Range = the Variable used is not acceptable
Examples
User1 = 0
Automate_DAC (DAC1, User1)
Loop: User1 = User1 +1 ;This will create a 0 to 10 volt ramp wave on DAC1
If User1 = 32767
{
User1 = 0
}
; add some delay or code here
Goto Loop
