Set PTT with Terminal or Script

[hamie]

I would like to get a copy if possible for use on my local ham repeater. I've got a rpi2 laying around!

@hamie: I send you an email

Could I contact you for some private conversations about your work?

I did the following steps

you need to install some development packages:

Code: Select all

apt-get install build-essential pkg-config qt4-dev-tools libqt4-dev libspeex1 \
                libspeex-dev libboost-dev libasound2-dev libssl-dev g++ \
                libspeechd-dev libzeroc-ice-dev ice-slice libpulse-dev slice2cpp \
                libcap-dev libspeexdsp-dev libprotobuf-dev protobuf-compiler \
                libogg-dev libavahi-compat-libdnssd-dev libsndfile1-dev \
                libg15daemon-client-dev libxi-dev


for more information please see http://wiki.mumble.info/wiki/BuildingLinux

Code: Select all

git clone https://github.com/mumble-voip/mumble.git

you have to edit the source files as shown above.

on the raspberry 2 I compiled with the following commands

Code: Select all

qmake -recursive main.pro CONFIG+="qt4-legacy-compat no-g15 no-server"
make

If you have any further questions don't hesitate to contact me.

The solution is great. We have many users on the repeater with mumble. Our next step is to connect two or more repeater.

Anyone compile this on the RPI3 yet?

[hamie]

Can you past your MainWindow.cpp on pastebin?
I'm having trouble with where to put

Code: Select all

QTimer *gpioPollingTimer = new QTimer(this);
connect(gpioPollingTimer, SIGNAL(timeout()), this, SLOT(onGpioPoll()));
gpioPollingTimer->start(100); // 100ms polling Intervall

did you have to edit the UI and add a timer in?

Is there a possibility to also have a copy of that image for a PI2 to our clubs repeater ?

Good day,

I found this topic while searching for information for my project.
'stephensworld' finished the issue where i was looking for.
I turned my Raspberry into an programming environment as described here.
I can't get the job done because i think I'm missing some information about editing the source files.
When i start compiling, there are errors.
Perhaps it has to to with versions because this topic is 1.5 years old, or I'm doing something wrong with the editing part of the source files. I'm not a programmer so i just follow the steps written by 'stephensworld'.
I did not succeed. Can someone rewrite the steps so it will match with the current software versions?
Otherwise is there an option to get a compiled version of Mumble client for Raspberry (with PTT signaling on GPIO interface).

Best regards,
Alex

Hi,
Is it possible someone with knowledge rewrites this handout?
It is not clear where to made the changes exactly (right place in source). When i try to compile i get much errors.
I'm not a programmer so i can just follow the steps written by 'Stephensworld'.
This post is 1,5 years old so i think it is not usable for current versions of mumble. Is it?
I hope someone can help to make a Mumble PTT radio (GPIO port signal) for Rasbian (Pi2 and 3)
Perhaps there is a compiled version available somewhere. One i can install on Raspbery Pi2/3.

Best regards,
Alex

Mine is a bit different on the the functions but here is some code blocks you can find to get it working
MainWindow.cpp

Code: Select all

void MainWindow::setupGui()  {
   updateWindowTitle();
   setCentralWidget(qtvUsers);
   setAcceptDrops(true);
QTimer *gpioPollingTimer = new QTimer(this);
connect(gpioPollingTimer, SIGNAL(timeout()), this, SLOT(onGpioPoll()));
gpioPollingTimer->start(100); // 100ms polling Intervall

Code: Select all

void MainWindow::destroyUserInformation() {
   UserInformation *ui = static_cast<UserInformation *>(sender());
   QMap<unsigned int, UserInformation *>::iterator i;
   for (i=qmUserInformations.begin(); i != qmUserInformations.end(); ++i) {
      if (i.value() == ui) {
         qmUserInformations.erase(i);
         return;
      }
   }
}
void MainWindow::onGpioPoll() {

 static bool pttGpioPrevState = false;
 static bool pttGpioState = false;

 QList<ClientUser *> talkingUsers = ClientUser::getTalking();
 // For someone else to be talking we have to be connected to the
 //server and there must be at least one person talking that isn't ourselves
 static bool pttPrev = false;
 const bool someoneElseTalking = g.sh && !(talkingUsers.empty() ||
 (talkingUsers.size() == 1 && g.uiSession ==
 talkingUsers.first()->uiSession));

 if (someoneElseTalking) {
        if(!pttPrev){
                system("echo 1 > /tty/pttctrl");
                pttPrev=true;
        }
 }

if(!someoneElseTalking){
        if (pttPrev){
                system("echo 0 > /tty/pttctrl");
                pttPrev=false;
         }
}

}

Thank you very much Hamie,

Can you tell me something about 'main.cpp'?
Where to place these parts exactly?

#include <wiringPi.h>
.....
wiringPiSetupSys();
pinMode(10,OUTPUT);
pinMode(25,INPUT);

In the source, #include statements are between " " instead of < >
