gbs-remote

A Pi Pico W based remote control for gbs-control scaler.

How to build your own

1. Aquire a Raspberry Pi Pico W (with headers if you don't want to solder).
2. Aquire a 1.3 WaveShare LCD (docs: https://www.waveshare.com/wiki/Pico-LCD-1.3) (eg link to purchase. https://www.aliexpress.us/item/3256802431350939.html).
3. Attach the lcd to the pico.
4. Put the Pi into boot mode (hold the boot button while connecting to a pc) and copy the lasted uf2 build to the pico.

Configuration

On first boot, the remote will boot into an access point mode. The remote's ssid and password will display on screen. Once connected, navigate to the configutation page (http://192.168.4.1) and enter your gbscontrol hostname and wifi credentials (your remote and gbscontrol must be on the same network). If successfully connected to wifi, the remote will reboot. The configuration page will be available on the remote from your network to configure or reconfigure the gbscontrol hostname, which defaults to gbscontrol.

Operation

Once connected to wifi and the gbscontrol's hostname is configured, the presets will disaply on screen. To select a preset, press the white button next to the option. Use the up and down directions of the joystick to scroll through the availble presets.

The left and right directions toggle an information screen displaying the links to the remote's configuration page and the gbscontrol's ui.

Pressing the center of the joystick will reload the presets from the gbscontrol.

Other Settings

Post Url: a url to make a post request to when a preset button is pressed. Useful for automation and tracking application (eg. Post to a homeassistant webhook to change lighting based on preset name).

Rest API

There is now a rest API to get a list of profiles and set the current profile.

'GET /api/presets' returns list of current presets

[
  {
    "id":"A",
    "display":"SNES"
  }
]

'POST /api/presets' with a JSON body containing the id and/or display of a preset. If found, the gbscontrol will switch to that preset.

Development setup

If you want to contribute or tweak the code:

1. Either download the latest release or download the display firmware directly from the ST7789 Driver for MicroPython at https://github.com/russhughes/st7789_mpy
2. Flash the firmware to the pico.
3. Using a IDE like Thonny to copy micropython files to the pico.
