6.6.6 Analog Outputs

flexAnaOutCalib

int flexAnaOutCalib(Flex_IOPin *pin, int value1, float volts1, int

value2, float volts2);

DESCRIPTION

Calibrates the response of the selected D/A converter channel as a linear function using the two

conversion points provided. Gain and offset constants are calculated and placed into a global ta-

ble. This function is non-reentrant.

PARAMETERS

pin Pointer to the information structure for this I/O pin.

value1 The first D/A converter value (0–1024).

volts1 The voltage corresponding to the first D/A converter value.

value2 The second D/A converter value (0–1024).

volts2 The voltage corresponding to the second D/A converter value.

RETURN VALUE

0: success

<0: error (not an analog output?)
