Modifying for 2x2 matrix
Closed this issue · 2 comments
Hi,
Thanks for the awesome tutorial! So, I have a 2x2 matrix of LED screens as opposed to your 1x2. I am wondering how to modify the code accordingly. It works just fine as a 1x2 display, but when I modify the options.parallel or other similar parameters in incidents.py and rpi-metro-display.py to try and accommodate a 2x2 display, the code doesn't work anymore and continues to draw Iike it's a 1x2 display.
When I wrote this I hadn't considered trying to accommodate different display dimensions so there are a lot of hard coded values hanging around. Since the API only returns 3 train times, you'll probably want to grab a larger font file from rpi-rgb-led-matrix.
For the main display screen (metro times) all you should need to do is change the hard coded values in draw_display to accommodate the larger font and increased display area.
The incident screens (service advisory/scheduled track work) are trickier because a lot more calculation is being done on the fly to draw the alert but it's the same idea. The incidents code is here.
Does that help?
