This function can only be used in an RTOS task. This function stops the
execution of the current task and returns control of the processor to
rtos_run(). When the next task executes, it will start it's execution on
the line of code after the rtos_yield().
All devices

set_adc_channel( )
Syntax:
Parameters:
set_adc_channel (chan [,neg]))
chan is the channel number to select. Channel numbers start at 0 and are labeled in
the data sheet AN0, AN1. For devices with a differential ADC it sets the positive
channel to use.
neg is optional and is used for devices with a differential ADC only. It sets the negative
channel to use, channel numbers can be 0 to 6 or VSS. If no parameter is used the
negative channel will be set to VSS by default.

Specifies the channel to use for the next read_adc() call. Be aware that you must wait a
short time after changing the channel before you can get a valid read. The time varies
depending on the impedance of the input source. In general 10us is good for most
applications. You need not change the channel before every read if the channel does
not change.
This function is only available on devices with A/D hardware.
