4.4.5 D/A Converter Outputs

int anaOutConfig(char configuration, int mode);
Configures the D/A converter chip for a given output voltage range, 0–10 V or ±10 V, and loads the cali-
bration data for use by the D/A converter API functions. This function must be called before accessing
any of the D/A converter channels.
NOTE: If you are using the analog outputs, you must configure the D/A converter chip
using the
anaOutConfig
A/D converter chip. This is because the A/D converter chip uses internal channels 4–7
on the D/A converter chip to bias the A/D converter input circuit, and the correct con-
figuration of the A/D converter would be affected if the D/A converter configuration
was changed later.
PARAMETERS
configuration sets the output configuration as follows:
0 = unipolar operation. (0–10V and 4–20 mA)
1 = bipolar operation. (±10V and 4–20 mA)
NOTE: When the D/A converter is configured for bipolar operation, the 4–20 mA chan-
nels change from 12-bit to 11-bit resolution.
mode is the mode of operation:
0 = asynchronous—an output is updated at the time data are written to the given channel
1 = synchronous—all outputs are updated with data previously written when the anaOutStrobe
function is executed.
RETURN VALUE
None.
