AmpliPi-POE-Touchscreen-Keypad

POE-powered touchscreen controller for AmpliPi A touchscreen keypad designed to control AmpliPi, using the Olimex ESP32-PoE board.

For the WiFi version, go to this repo: https://github.com/kjk2010/AmpliPi-Touchscreen-Keypad

Currently a work in progress, nearing initial release.

Built using VS Code with Platform.IO.

Currently supported hardware

• Olimex ESP32-PoE board
• ILI9341 or ILI9488 compatible TFT touchscreen

Basic setup instructions

1. Wire the TFT touchscreen to the ESP32-PoE using the UEXT connector (PCB details coming soon). Edit platform.ini as needed.

Pin selection for the Olimex ESP32-PoE board's UEXT connector

• TFT_CS=15
• TFT_RST=5
• TFT_DC=2
• TFT_MOSI=13
• TFT_SCLK=14
• TFT_MISO=16
• DTOUCH_CS=4

2. Clone this Github project
3. Upload Filesystem Image to ESP32-PoE (this uploads the files in the data folder to the ESP32's file system)
4. Compile and upload to ESP32-PoE
5. Replace app.py from the amplipi folder on the AmpliPi server. This patch includes the 'get_stream_image' function to provide album art to the controller. Requires 'pillow' python3 library (pip3 install pillow).

Note: WiFi functionality on the ESP32-PoE is not available in this repo. If WiFi is needed, use the WiFi repo: https://github.com/kjk2010/AmpliPi-Touchscreen-Keypad

To do items

• Add support for stream commands: Play/Pause, Next, Stop, Like
• Add local inputs to source selection screen
• Show configured names for local inputs
• Add AmpliPi preset functionality
• Put metadata into sprites and scroll long titles
• Split display functions from update data functions. Display functions should be drawing everything from memory, and update functions should be updating the data and triggering a draw if data has changed.
• Show album art for all available stream sources (will require patching AmpliPi)
• Switch to JPEG images instead of BMP in order to speed up downloading and display of album art
• Add support full multiple screen sizes
• Add POE and Ethernet capabilities, utilizing the Olimex ESP32-POE board
• Add source selection screen
• Add local source to source selection screen
• Add settings screen: Change Zone, Change Source, Reset WiFi & AmpliPi Host, Reset Touchscreen
• Move zone selection to settings screen and save to config file
• Show album art for local inputs
• Support controlling one or two zones
• Add mDNS resolution support so touchscreen can find amplipi.local

Future features

• Screen time out options (PIR, touch, screensaver showing full screen only metadata?)
• Switch to using SSE or WebSockets, whichever AmpliPi server offers, instead of spamming API
• Simple web server to allow changing of AmpliPi name/IP, display settings, color scheme
• Add OTA upgrades
• Integrate Home Assistant control options on a second screen
• Add support for expansion units (more than 6 output zones)
• Control stream sources like Spotify playlists or Pandora stations
