4.2.5 D/A Converter Outputs
The following sample programs are found in the
DAC
subdirectory in
SAMPLES/BL2000
.
•
DACAL.C
—This program demonstrates how to recalibrate an D/A converter channel
using two known voltages, and defines the two coefficients, gain and offset, that will be
rewritten into the D/A converter's EEPROM simulated in flash memory. Note that this
sample program will overwrite the calibration constants set at the factory.
•
DAOUT1.C
—This program outputs a voltage that can be read with a voltmeter. The out-
put voltage is computed using the calibration constants that are read from the EEPROM
simulated in flash memory.
•
DAOUT2.C
—This program demonstrates the use of both the D/A and the A/D convert-
ers. The user selects both the D/A converter and A/D channel to be used, then sets the
D/A converter output voltage to be read by the A/D channel. All activity will be dis-
played in the
STDIO
window.
4.2.6 TCP/IP Sample Programs
TCP/IP sample programs are described in Chapter 5.
