YAWL firmware

You may download a ready-to-use firmware yawl_controller.bin .

Standard firmware

You can get further information on the various WLED firmware versions https://kno.wled.ge/basics/install-binary/

Build custom firmware

Also you may compile the firmware by self using Visual Studio Code and Platformio.

• Download and install Git client: https://git-scm.com/downloads.
• Download and install Visual Studio Code: https://code.visualstudio.com/download.
• Install PlatformIO extension in Visual Studio Code: https://docs.platformio.org/en/latest//integration/ide/vscode.html#installation
• Download WLED Github Master ZIP: https://github.com/Aircoookie/WLED/archive/refs/heads/master.zip
• Unpack in directory somewhere
• “Open folder” in Visual Studio Code
• Build project with Ctrl+Alt+B hotkey
• Build standard WLED.
• If the file is created successfully then you can proceed to the next step, if not please read this article for more information.
• Copy platformio_override.ini to WLED folder
• Build custom WLED firmware.
• Please find built firmwae in WLED/build_output/firmware folder

If you still have questions for more information please read a step-by-step guide at this page of the WLED Wiki

Build the firmware from command line

• Edit file env.cmd from yawl-controller/firmware/ESPHome/ directory.
  • Set PYTHON_PATH to Python installed on your system.
  • Set PLATFORMIO_VENV to path to virtual environment where Platformio will be installed.
  • Set PLATFORMIO_REPO to url for Platformio repository. Default: https://github.com/platformio/platformio-core
  • Set PLATFORMIO_BRANCH to branch name or tag in Platformio repository. Default: master
  • Set WLED_REPO to url for WLED repository. Default: https://github.com/Aircoookie/WLED
  • Set WLED_BRANCH to branch name or tag in WLED repository. Default: master
• Run install_platformio.cmd. The latest version of Platformio will be installed.
• Run compile.cmd. The firmware will be compiled and copied to yawl-controller/firmware/WLED/ directory. File yawl_controller_WLED_{WLED_VERSION}.bin will be created, where {WLED_VERSION} - version of WLED.

Connect controller to computer

YAWL Controller	USB to Serial Adapter
3.3v	3.3v
Ground	Ground
IO0	Ground
TX	RX
RX	TX

Flash firmware

Download flasher https://github.com/esphome/esphome-flasher/releases Open the flasher tool.

• Serial port: select COM port where the controller is connected (there is probably only one option).
• Firmware: Browse to the location where you downloaded your compiled firmware and select your firmware.

• Click Flash ESP and wait.

The controller will be flashed now, you can follow the progress in the console window. When finished writing the firmware, switch off controller.

Hardware Setup

GPIO Pinout

| Pin | Function | | — | —| | GPIO0 | Push Button | | GPIO1 | LED CLK | | GPIO2 | LED DATA | | GPIO4 | IR Receiver | | GPIO12 | Relay | | GPIO14 | Temperature Sensor |

3-Wire LED Strip

1. Select 3-wire LED Strip like a WS281x
2. Data GPIO: 2

4-Wire LED Strip

1. Select 4-wire LED Strip like a APA102
2. GPIOs:
   • Data GPIO: 2
   • Clk GPIO: 1

Temperature

YAWL Controller uses GPIO 14 for temperature sensor DS18B20 (DALLAS)

IR receiver

YAWL controller uses GPIO 4 for IR receiver.

Information about infrared receivers https://kno.wled.ge/interfaces/infrared/

Relay

YAWL controller uses GPIO 12 for controlling relay.

Installing relay https://kno.wled.ge/features/relay-control/

Button

YAWL controller uses GPIO 0 for button.

Multi-strip Support

You are able to use multiple LED outputs from one yawl-controller. Pins and LED numbers can be easily configured in LED settings, you don’t need to re-compile code for your specific setup. You may use use two specific LED pins, GPIO1 (CLK) and GPIO2 (DATA) for two 3-wires strips
