I posted this message in the beginning of the month and there seemed to be no interest. This probably is not a high priority on the list right now. 73 Marshall - ke6pcv From: App_rpt-users [mailto:app_rpt-users-bounces@lists.allstarlink.org] On Behalf Of Marshall Oldham Sent: Monday, February 06, 2017 2:37 PM To: app_rpt-users@lists.allstarlink.org Subject: [App_rpt-users] Pi 3 Use of GPIO for PTT and COS Greetings, Just wondering if anyone has been able to modify SimpleUSB or USBradio channel drivers to be able to use GPIO pins on the PI 3 for PTT and COS. This would be very useful for using potted sound fobs where you can not access the COS and PTT pins. I have noticed that the VK Link guys have channel drivers that support this feature. http://nevarc.net.au/manual/index.php?page=Wiring+to+a+radio Check out their Chan_SimpleUSB, Chan_USBradio configurations. Go to there main page http://vklink.com.au/manual/index.php?page=Main+page Then scroll down to "Choosing a Channel Driver" and click on that link. Looks like the work has been done, wondering if this could be added to official DIAL release features. Sure would be nice for folks that want to experiment without having to spend very much to play in the Allstarlink technology.
