[arm-allstar] CM108 FOB

[Michael Durkin]

Thanks for the fast response Doug ...

looking at the allstar image .. i found that it looks like you guys are
using hamlib3 code with no modifications in regards to cm108

I have 2 cm108 USBID 0d8c:000c with the four GPIO pins accessible .... i
have already modified the code to successfully detect the cm108 -- i have
not moved on yet to testing GPIO.

I thought allstar group had taken hamlib3 code farther -- because i seen
some one using the  PTT(out) and dcd(carrier detect) ....

guess im still looking for whom wrote lines 243-->246 of cm108.c in hamlib3.

Im looking to change cm108.c code to also input a PTT(*Input*) so that
SDR's that dont have a physical PTT input -- can use a microphone PTT
circuit to trigger PTT. UHFSDR is one such example of a SDR with no
hardware to software PTT. you can see my UHFSDR on my qrz page -- KC7NOA

almost forgot the page that shown more than just PTT and DCD ...
http://www.garydion.com/projects/usb_fob/ its the exact same FOB i have --
and looked like their are plenty of them ...
