Framework Laptop 16 - Input Module Software

This repository contains a python library and scripts to control the (non-keyboard) input modules, which is currently just the LED Matrix.

Installing

Pre-requisites: Python with pip

python3 -m pip install inputmodule

Control from the host

To build your own application see the: API command documentation

Permissions on Linux

To ensure that the input module's port is accessible, install the udev rule and trigger a reload:

sudo cp release/50-framework-inputmodule.rules /etc/udev/rules.d/
sudo udevadm control --reload && sudo udevadm trigger
Common commands:
Listing available devices
> ledmatrixctl
More than 1 compatible device found. Please choose with --serial-dev ...
Example on Windows: --serial-dev COM3
Example on Linux:   --serial-dev /dev/ttyACM0
/dev/ttyACM1
  VID:     0x32AC
  PID:     0x0020
  SN:      FRAKDEBZ0100000000
  Product: LED Matrix Input Module
/dev/ttyACM0
  VID:     0x32AC
  PID:     0x0020
  SN:      FRAKDEBZ0100000000
  Product: LED Matrix Input Module
Apply command to single device

When there are multiple devices you need to select which one to control.

# Example on Linux
> ledmatrixctl --serial-dev /dev/ttyACM0 --percentage 33

# Example on Windows
> ledmatrixctl --serial-dev COM5 --percentage 33

Graphical Application

Launch the graphical application

# Either via the commandline
ledmatrixctl --gui

# Or using the standanlone application
ledmatrixgui

Other example commands

# Show current time and keep updating it
ledmatrixctl --clock

# Draw PNG or GIF
ledmatrixctl --image stripe.gif
ledmatrixctl --image stripe.png

# Change brightness (0-255)
ledmatrixctl --brightness 50

All commandline options

Update the Firmware

First, put the module into bootloader mode.

This can be done either by flipping DIP switch #2 or by using one of the following commands:

> ledmatrixctl --bootloader

Then the module will present itself in the same way as a USB thumb drive. Copy the UF2 firmware file onto it and the device will flash and reset automatically.


### Check the firmware version of the device

```sh
> ledmatrixctl --version
Device Version: 0.1.7
By looking at the USB descriptor

On Linux:

> lsusb -d 32ac: -v 2> /dev/null | grep -P 'ID 32ac|bcdDevice'
Bus 003 Device 078: ID 32ac:0020 Framework Computer Inc LED Matrix Input Module
  bcdDevice            0.17
