Re: configuring cm108 for PTT, I seem to be doing something wrong.
|
I had to play around with the RTS DTS in the direwolf.conf to get it to work with a Easy Digi that we used as a APRS gateway/digipeater/tracker.

Hello Joe,
Which sound device are you using?? Is it something you made or maybe a pre-made solution like a DINAH or other device?? Can you confirm if the GPIO 3 pin coming off the CM sound chip is changing assuming you setup a Direwolf test beacon running every minute??
The easiest way here would be to just use a volt-meter to detect changes.? I would also recommend to enable PTT debugging when you start Direwolf using "-do" so you can see the logs when Direwolf thinks it's asserting PTT.

I first set up Direwolf as a receive only Igate.? This works fine (K2EVK-10)
I Have not been able to get transmit to work (day 4);
Startup, no errors:
pi@raspberrypi:~ $ direwolf
Dire Wolf version 1.6
Includes optional support for:? cm108-ptt
Reading config file direwolf.conf
Config file: LOGDIR on line 502 is replacing an earlier LOGDIR or LOGFILE.

Audio device for both receive and transmit: plughw:1,0? (channel 0)
Channel 0: 1200 baud, AFSK 1200 & 2200 Hz, E+, 44100 sample rate / 3.
Using /dev/hidraw0 GPIO 3 for channel 0 PTT control.

Here are lines from my direwolf.conf:
# Linux ALSA is complicated.? See User Guide for discussion.
# To use something other than the default, generally use plughw
# and a card number reported by "arecord -l" command.? Example:
ADEVICE? plughw:1,0

#CHANNEL 0

MODEM 1200
