From a0428724cf9bd73185321274a5918e9d43778967 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 19 Oct 2021 16:45:17 +0200 Subject: auxdisplay: ht16k33: Add support for segment displays The Holtek HT16K33 LED controller is not only used for driving dot-matrix displays, but also for driving segment displays. Add support for 4-digit 7-segment and quad 14-segment alphanumeric displays, like the Adafruit 7-segment and 14-segment display backpack and FeatherWing expansion boards. Use the character line display core support to display a message, which will be scrolled if it doesn't fit.
