Install Ham Clock on a Raspberry Pi3 with a 7inch touch display
Download the Raspbian Image from https://www.raspberrypi.org/downloads/ and install it on a sd card. For this i use https://www.balena.io/etcher/. Put the sd card in the Raspberry Pi and start the system. Make the basic setup as you like. For the first installation it makes sense to connect a keyboard and mouse to the Raspberry Pi. This will not be necessary later. Alternatively, access is also possible via VNC.
Before I install new software I start an update. I start the terminal and enter the following command
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade reboot
Start the terminal again and install Ham Clock
curl -o ESPHamClock.zip http://www.clearskyinstitute.com/ham/HamClock/ESPHamClock.zip unzip ESPHamClock.zip cd ESPHamClock make -j 4 hamclock
This example command will build HamClock at 800×480 pixels for X11. Type
make help for a complete list of other sizes and desktop environments
Now you can start Ham Clock with
After start you can take some setups. That’s all. Is that easy.
Many thanks to Elwood, WB0OEW. It looks beautiful and works great.
For more information about Ham Clock, operating instructions and much more have a look here: http://www.clearskyinstitute.com/ham/HamClock/. There you can also read what to do if another monitor is used.
Touch Display 7 inch
I use the original 7 inch touch display https://www.raspberrypi.org/products/raspberry-pi-touch-display/. There are many ready-made cases for this on the Internet. For my case i must rotate the screen. It is easy. Open the config.txt file
sudo nano /boot/config.txt
and add the following text to the beginning of the config.txt file
After that please save the file and reboot.
lcd_rotate=1 90 degree
lcd_rotate=2 180 degree
lcd_rotate=3 270 degree
If you want to disable the screen saver it is easiest to install a screen saver utility
Start the terminal and enter
sudo apt-get install xscreensaver
After that please reboot. Open the utility and deactivate the screen saver.
Create desktop shortcut
Create an empty “HamClock.desktop” file on the desktop and open it with a text editor and add the following content
[Desktop Entry] Name=HamClock Comment=Open HamClock Exec=/home/pi/ESPHamClock/hamclock Type=Application Encoding=UTF-8 Terminal=false Categories=None;
