From 0060b101df331c3b4fcdae76e6fcb232daa2ea74 Mon Sep 17 00:00:00 2001 From: Alex Goris Date: Sun, 5 May 2019 23:43:18 +0200 Subject: [PATCH] feat(LED Matrix Display): Added support for a LED Matrix display This commit adds support for a specific LED Matrix display, which can be used to show the number of found devices on a rather large display. We (hackerspace Brixel) used this on the mini Maker Faire Gent 2019 to show the number of found devices throughout the event --- include/globals.h | 6 +- include/irqhandler.h | 5 +
