Software

In the software folder you will find two programs:

  • test is a simple script for doing hardware debugging. It provides a quick way to check that the LEDs are all working, and to toggle the relay on and off
  • doorlock is a submodule of another git repo: https://github.com/swanseahackspace/doorlock. This is currently incompatable with this hardware, but will be modified to support both it's original hardware and the ESP-32-C3 via a flag in the config file.

Requirements

  • Arduino IDE or equivalent
  • Arduino Libraries:
    • Adafruit Graphics
    • Adafruit SSD1306 Wemos Mini OLED

Installation

  1. Clone git repo
git clone https://github.com/swanseahackspace/roller-shutter-controller
  1. Go into the doorlock directory
cd software/doorlock
  1. Initialise the submodule
git submodule init
  1. Update the submodule
git submodule update

  1. Open .ino file in Arduino IDE

  2. Follow the Wemos/Lolin C3 Mini Arduino development guide

  3. Plug the board into your machine via the USB type-C port on the ESP-32-C3

  4. Check the correct port is set in the Arduino IDE (Tools -> Port)

  5. Upload the code to the ESP32

Troubleshooting

Errors uploading code to ESP-32-C3 Use the following procedure:

  • Hold on Button 9
  • Press Button Reset
  • Release Button 9 When you hear the prompt tone on usb reconnection
