Thread 'main' panicked when trying to display a greyscale image

[cyber199]

Trying out the LED modules and I get an issue when trying to show a greyscale image and I don't know if I'm encountering a bug or just being an idiot. It happens with both my own image and the examples found in this repo ("/res/greyscale.gif", "/res/stripe.gif", and "/res/stripe.png"). With RUST_BACKTRACE=full set I get the following:

$ ./Downloads/inputmodule-control_cli_linux led-matrix --image-gray ~/Pictures/greyscale.gif

I am running Linux Mint 21.3, which I know isn't officially supported, but being based on Ubuntu Jammy I didn't think it would be a vast departure. Everything else I've tried works, including --image-bw, so I'm hoping the problem isn't with my machine.

Same problem here display_gray_image_cmd uses the SendCol for every column but after a few calls, it seems to panic with the time out error

Sleeping after each command sent would "fix" this, but I don't understand why sending few columns of data in a row is too much to handle

I was trying to create a black and white video playback feature by using the SendCol and CommitCols commands, but after about 5 or 6 of these commands invoked in a row, it times out and panics. Sleeping between the commands sent would let me get somewhere, but the video fps can't go above 10 because of this

I thought the USB 2.0 connection is the limit, but I guess its not? What's going on with this?

I have the same problem on Ubuntu 22.04.

I encountered a similar error on Arch Linux when running inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --all-brightnesses.

Here's what I did:

1. Install inputmodule-control from AUR
2. sudo udevadm control --reload && sudo udevadm trigger
3. RUST_BACKTRACE=full inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --all-brightnesses

The error and stacktrace are:
