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

2. Go into the doorlock directory

cd software/doorlock

3. Initialise the submodule

git submodule init

4. Update the submodule

git submodule update

5. Open .ino file in Arduino IDE

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

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

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

9. 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
