Activate PTT pin on CM108 without asterisk
Is there a way to tell pin 13 on the CM108 sound card to activate High vs Low? Although this is off topic, I thought maybe people here would know: I want to use a USB sound FOB for APRS with XASTIR, and I want to see if I can use a cheap sound card instead of a TNC. If nothing else, I will have to use a VOX circuit, but it would be cool if I could script XASTIR to tell the USB card to activate high/low when it PTT's. If anybody has experience with XASTIR, do you know if you can even use sound cards in it? Or does it have to be a TNC. 73, Skyler KDØWHB -- Skyler Fennell amsatnet.info KDØWHB electricity440@gmail.com
You could just invert it using a pnp and a 10k resistor. Corey

Maybe my question is not clear: I want to know what command can be operated to make the Pin on the CM108 chip to activate? What command does Asterisk run so that it activates the PTT button on the USB fob? On Sat, May 9, 2015 at 8:10 AM, Corey Dean <n3fe@repeater.net> wrote:

Skyler, You still maybe not so clear. Just some thoughts... Are you using app_rpt or even asterisk for the task? You will find the answer in the source code. It's not going to be a single simple command. If not using app_rpt, you will need most of the source code for the device. Basically you will be outputting a bit/byte to a address / bit-banging once you have established the parameters for the device. If using vox, don't forget to add a (X)ms delay between tx key to tx data for switch activation time or you will loose beginning of the 1st frame data. ...mike/kb8jnm

What command does Asterisk run so that it activates the PTT button on the USB fob?

See invertptt= http://svn.ohnosec.org/svn/projects/allstar/astsrc-1.4.23-pre/trunk/configs/... You may still require a pull-up resistor to get the CM108 to actually work in circuit. Thanks, Bob kk6ecm Sent from iPad
