Installing an OLED display on a MMDVM repeater

After the article on the configuration and installation of a Nextion screen on a MMDVM repeater, let’s see together how to integrate a small OLED display on MMDVM.

This type of display is known by the reference SSD1306, it measures 27 millimeters for a display definition of 128 x 64. There are two variants of the SSD1306 display, one running on SPI bus and the other on I2C. I chose the I2C bus model, recognizable by these SCA and SCL pins. It is monochrome but also exists in a yellow and blue two-color version. Only the lines on the top of the display are yellow. This is the model I use.

OLED SSD1306 display

Software prerequisites

You are connected to Raspberry Pi.

First of all, we will validate the SPI and I2C buses of the Raspberry Pi, thanks to the configuration menu.

 

sudo raspi-config

 

We now install software packages to manage these buses.

sudo apt-get install build-essential git-core libi2c-dev i2c-tools lm-sensors

In order for the modules to start we must indicated them in the modules file

sudo nano /etc/modules

You must have these two lines

i2c-dev
spidev

(Exit with Ctrl-X and Yes to save)

We restart the Raspberry Pi

sudo reboot

After reconnecting, we must find the ports i2c and spi

ls /dev/i2c*
ls /dev/spi*

Connecting the Display

The SSD1306 is an I2C bus version. The connection is made as shown below.

Detection Test

We will check that the wiring is correct and that the screen is detected on the I2C bus.

Start the following command.

i2cdetect -y 1

 

Equipment 3c appears. This is the SSD1306 screen.

Installing the OLED Display Communication Library

If you did not install git on your Raspberry Pi, I suggest you run this command.

sudo apt-get install git

Download now the ArduiPi_OLED library (directly on github).

git clone https://github.com/hallard/ArduiPi_OLED

then run the software compilation

cd ArduiPi_OLED
sudo make

Recompiling MMDVMHost

Let’s update MMDVMHost with these few instructions. The compilation will take several minutes.

cd /opt/MMDVMHost/
make clean
sudo make -f Makefile.Pi.OLED
pi@raspberrypi:/opt/MMDVMHost $ sudo make clean
rm -f MMDVMHost *.o *.d *.bak *~ GitVersion.h
pi@raspberrypi:/opt/MMDVMHost $ sudo make -f Makefile.Pi.OLED
echo "const char *gitversion = \"24358357e890a928f0053bcedd748123d7a6b9c2\";" > GitVersion.h

Updating the MMDVMHost Configuration File

Here is the final step. Now, in the [General] section of the MMDVM.ini file, we have installed an OLED screen

sudo nano /opt/MMDVMHost/MMDVM.ini
[General]
Callsign=F5ZKS
Timeout=600
Duplex=1
# ModeHang=10
RFModeHang=10
NetModeHang=3
#Display=Nextion
Display=OLED
#Display=None
Daemon=0

It refers to the OLED section that we do not have to change

[OLED]
Type=3
Brightness=0
Invert=0

Finally, we need to restart the Raspberry Pi

sudo reboot

Result

The display SSD1306 lights up. It is waiting for traffic

SSD1306 I2C display connected to Raspberry Pi, and driven by MMDVMHost

On the talk group TG2, WA4BPS is displayed, it is retransmitted on the Time Slot 2 in DMR

    I have a problem with the OLED display now. It woks perfectly for some time then for no reason

    1. Bonjour Stéphane,

      Dans le code OLED.cpp (https://github.com/g4klx/MMDVMHost/blob/master/OLED.cpp) semble avoir prévu l’utilisation de la version SPI de l’écran OLED. Malheureusement, je ne sais pas vous dire quel serait le paramètre et le cablage correspondant. Peut être vous faut-it rechercher la réponse ou poser la question sur le groupe MMDMV sur yahoo https://groups.yahoo.com/neo/groups/mmdvm/conversations/messages

      (Translation)
      In the OLED. cpp code (https://github.com/g4klx/MMDVMHost/blob/master/OLED.cpp) seems to have foreseen the use of the SPI version of the OLED display.

Maybe you need to look for the answer or ask the question on the MMDMV group on yahoo https://groups.yahoo.com/neo/groups/mmdvm/conversations/messages

    is it possible to delete or modify this IDLE message, because there is also a MMDVM scrolling that passes and after a while this famous message, but I can’t find in the files where you can change it.

    73 thanks for the info

    1. Bonjour Jean-Charles,

      Le mot “idle” signifie inactif ou pas d’émission. Il s’affiche lorsque le hotspot (ou le relais) est en veille. Il s’affiche sur l’écran aléatoirement ou en défilant, comme un écran de veille.

      Si d’aventure vous voudriez remplacer le mot ‘idle’, le seul moyen que je vois est de modifier le code C de la fonction COLED::clearCWInt() qui est dans le fichier OLED.cpp puis de (re)conpiler le MMDVMHost.

      Ici ligne 363 (https://github.com/g4klx/MMDVMHost/blob/6ae4735598d179db21b58ad92eee06794104cc4f/OLED.cpp)

      73

      (Translation)
      Hello Jean-Charles,

      The word “idle” means inactive or no emission. It is displayed when the hotspot (or repeater) is in standby. It is displayed on the screen randomly or by scrolling, like a screen saver.

      If by adventure you would like to replace the word’ idle’, the only way I see is to change the C code of the function COLED:: clearCWInt () which is in the OLED. cpp file and then (re)condition the MMDVMHost.

      Here line 363 (https://github.com/g4klx/MMDVMHost/blob/6ae4735598d179db21b58ad92eee06794104cc4f/OLED.cpp)

    Hello, I installed an oled 0.96″ 12C SPI screen on my MMDVM card that is not enabled. So I tried with the procedure below but without success. The problem is the impossibility to open “raspi-config” with Putty
    pi-star@pi-star(rw):~$ sudo raspi-config
    sudo:raspi-config: command not found

    That’s my problem………
    Thank you for your help

    1. Bonjour,

      A priori vous utilisez pas une distribution debian, mais une image pi-star. Vous pouvez directement mettre en service votre écran OLED depuis le menu de configuration MMDVMHost depuis le serveur pi-star.
