Adding a Display to AMBEServer

An AMBEServer provides a great platform for supporting applications like DummyRepeater, which need a platform to convert audio to AMBE and back again.

In previous blog posts we have discussed using the AMBEServer with DummyRepeater, but have always used a display on another computer or HDMI monitor to accomplish this task.

I decided I would like to see if I could get a Raspberry Pi display attached to an AMBEServer for user interaction without the need for a remote computer display or HDMI connected monitor.

I decided to try the Adafruit Pi TFT as a display.  Here are the early results.  After receiving the PiTFT, I followed the assembly instructions and software install instructions. I used the deb file method rather than loading a new image.

The display came right up.  Here are the results.

As you can see this all stacks up nicely, I just need to come up with a support and a case to hold it all!

The current UI isn’t optimized for the 320×240 display yet, but as you can see the touch PTT/Transmit button is clearly visible and the TFT touch function of the board works.  The board also supports 4 buttons that UI designers could use for a menu operated or similar system.  Additionally, adding a USB or Bluetooth keyboard and mouse are supported.
