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

Questions

How big is the Roller shutter controller PCB?

It measures 96 × 92 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Roller shutter controller use?

36 parts, built around the TSR 1-24120, TSR 1-2433 and EC2-3NU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Roller shutter controller KiCad files?

From the swanseahackspace/roller-shutter-controller repository on GitHub, at the commit this page was made from: the board is hardware/roller-shutter-controller.kicad_pcb and its schematic hardware/microcontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Roller shutter controller design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
