A USB serial connector for CAT (computer aided tuning) also appeared after rebooting.
RASPBERRY PI 2 FLDIGI INSTALL
I needed to install pavucontrol from the repository and reboot the machine for it to actually recognise the USB audio interface, but after that it all worked fine. I installed the version of FLdigi from the Raspbian repository, but this is quite an old version, 4.1.01, it’s up to 4.1.13 at the time of writing, so I will probably uninstall this and compile. For WSJT-X you just have to suck it up and move the program window up and to the left using Alt-Space-M FLdigi 4.1.01 running on the Pi4 Under settings appearance setting the bar to medium and at the bottom of the screen meant it got out of the way when I was using FLDigi. The main gotcha is that the raspbian menu bar pushes programs down by the width of the menu bar, which meant I couldn’t see the operational controls at the bottom of FLdigi. By default it will be display's size minus The various tricks to remap the screen size in /boot/config.txt like # uncomment to force a console size. At home I can use RDP into the box to get a bigger screen on my PC. It’s not the most convenient way of using a program, but it gets the job done. I thought this was a showstopper until I discovered the Alt-Space command, which can be followed by M to let you move the window with the touchscreen to see the otherwise inaccessible parts, which usually include the OK and Save Config buttons. The bottom and often the right is cut off. Lcd_rotate=2 The Raspberry Pi official touchscreen is low resolution 800×480Īnd a lot of software just can’t believe you are running it on such a small screen, so the software window doesn’t get small enough to fit on the screen. Sudo nano /boot/config.txt to add the line It came up first time, the keyboard connected easily using just the touchscreen, which prompted entering a six-digit number on the keyboard to pair it.The screen starts upside down in the frame but this is easily fixable with The touchscreen needs a reasonably firm press, this is no responsive smartphone screen, and being so small it is sometimes hard to get the right target, even with a conductive stylus, particularly as I set the font size a little smaller to use the screen area more. Although I started it up on ethernet, the onboard Bluetooth meant I could connect a Bluetooth keyboard using just the touchscreen, and then set up the wifi in the usual way. With the touchscreen I didn’t need all that. Normally you then have to remember to add the empty file ssh to the boot partition with the PC so you can talk to the damn thing, and perhaps wrangle the wireless config if the Pi doesn’t have Ethernet.
Setting it up was surprisingly painless – blow a new 16Gb SD card with Raspbian, connect screen to the 5V and 0V on the GPIO and the ribbon cable to DSI.
Also to stop FLdigi getting hopelessly confused on my main PC – with two sound cards already adding a third sound card as interface for the radio meant portaudio, whatever that is, gets hopelessly confused on Windows and loses touch with the hardware intermittently.
RASPBERRY PI 2 FLDIGI PORTABLE
The aim of this is to be able to run FLdigi and WSJT-X 1 in a portable setup. I got a new Raspberry Pi v4 and the official touchscreen.
