12.4.7 DemoAppADC
The Analog to Digital Converter (ADC) example:
• takes a number of samples from the designated ADC
• gets the median ADC value to remove some variability caused by noise (the median
gives a more reproducible value than the arithmetic mean)
• converts the value to a voltage based on the supplied conversion factor
• prints the voltage value to the Logger port.
This process repeats approximately once a second until the demo is halted. Note that this
application uses network-specific calls.
1. Select the DemoAppADC Workspace from the drop-down list at the top left-hand corner of
the IAR IDE screen. Open the APL.c file, as shown below:
Figure 12-58: DemoAppADC - Selecting the Workspace
2. Now build, load and execute DemoAppADC. The instructions for building, loading and
executing the code are the same as in Section 12, except that after building the application,
the executable bin file is: …/DemoAppADC/exe/xxx-DemoAppADC.bin .
