The following steps explain how to implement random-channel-selection MUX control.
channel
A value (0–4095) corresponding to the voltage on the analog input channel. A value of
-4096 indicates an overflow or an out-of-range condition.
1. Set the maximum number of external A/D converter channels:
2. Provide an application function that will do the following:
#define MAX_ADCHANNELS <new value>
• Select the A/D converter channel via the hardware MUX circuit. Be sure to initialize
• Change the _adc_mux_channel index to the channel selected.
• Set the adc_conversion_done flag to FALSE.
• Then call your routine with the A/D converter channel selected.
• Wait in a nonblocking wait routine for the adc_conversion_done flag to become
• Read the A/D converter.
• Repeat the sequence by calling your routine with the A/D converter channel selected.

The MAX_ADCHANNELS macro is set to a default value of 1,
which can be changed by adding the following line to your
program.
