R36 Control Centre

This service provides the basis for the goal of supporting any variant of the R36S with dArkOS RE.

On early boot, the configuration service checks the device tree and:

1. If there is no config, reference the r36s_device file with default settings, create a config for the supported device and apply the default hardware settings
2. If there is a configuration and the hardware is different, it updates the configuration and applies the default hardware settings.
3. If there is a configuration and the hardware is the same, apply the configuration file, except change the selected LED service file.

Version 0.3 Initial Testing Release

• Controls LED Services for clones, R36S and soysauce.
• Controls Gamma Setting
• User interface "R36 Control" under "Options"
• Updated dtb files included.
• Device list updated
• Logging to /boot/

DTB-LED.zip

The Zip contains the updated dtb files for the supported devices listed below, the installation script, and the tar files.

To install

1. Replace the dtb files and boot.ini for your device from the zip
2. Copy the script and tar to the ports folder on your ROMS card.
3. Load Emulationstation and run it from the ports.

The following dtbs are included in release 0.2

Let me know if you'd like any other changes (sorting, grouping by status/type, etc.). Notes:

• Released SoySauce dtbs have had uhs removed from the SD Card to increase compatibility. This does not affect speed as proven here https://github.com/southoz/dArkOS-G80CA-RE/issues/28#issuecomment-3976696239
• The control centre will work with any dtb file; however, the device is treated as unknown and may be affected by the LED configuration in the DTB file.
• Unknown dtb files are given access to all LED scripts while known devices are presented with only compatible scripts.

The following dtbs will be in release 0.3 shortly

Overview

To resolve the issue of supporting clones, genuine R36S devices, and soysauce models,

• Each device dtb will need to have the LED elements removed from the gpio_led, battery, and charger nodes so that LED control passes to the system.
• Default gamma values are not tuned where the SoySauce devices are oversaturated while the G80CA is understauated
• The default Audio Path is SPK_HP, and some devices require it to be set to SPK unless the Headphones are plugged in.
• Kodi amplification needs to be initially set per device.
• Some of the Clone V12 devices have an audio initialisation issue and need to go through a sleep-wake cycle to initialise audio.

Note Genuine R36S devices use PMIC control over the Green or System LEDs so they are never available to the system.

My test devices are the V21, Soy Sauce V5 Batch 2661, G80CA V1.2 Panel 8 and a V12 Clone Variant 3, thankfully donated by Ace007186 over on Discord.
