<div class="moz-cite-prefix">In the app_rpt.c source there is
mention of cop 31, Channel Selector for Parallel Programmed Xcvr
and ppp16. Have asked several times on the list about this but
never got a response. Any gurus out there have any info?<br>
<br>
BCD channel steering would certainly be a better solution than
pulsing the up down selector.<br>

<div dir="ltr">Has anybody ever created a remote base with a radio
like the SM120 16 channel commercial radio? Would it be possible
to use the URI to specify the channel I want to go to, for
example, hooking a GPIO pin to the "channel -" button and
hooking another to the "channel +" button? So if I am on channel
1 and want to go to 7, the GPIO for "chan +" would have to pulse
6 times. That wouldn't be very reliable probably because there
is no confirmation that you are actually on the right channel,
but this is how I would do it:

</div>
<div>When a channel change is requested, pulse 16 or more times
on the "chan -" button to make sure it is on channel 1. Then
count the + button up to the channel number you want to go to.
That idea, however wouldn't work on the SM120 because going
below channel 1 brings you back to 16. </div>
<div><br>
</div>
<div>Another idea I have is put one channel on a frequency
reference (maybe those 150mhz re-broadcasts of radio
stations?) and then find the channel you want based on that
reference. </div>
<div><br>
</div>
<div>Another idea yet would be to use a few more GPIO pins to
see which elements of the 7-segment displays are lit up and
then make an estimate on which channel you currently are on. </div>
<div><br>
</div>
<div> Any other ideas? <br clear="all">
