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.
