From 349cbe949b9622cc05b148ecfa6268cbbae35b45 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Beh=C3=BAn?= Date: Mon, 4 Jul 2022 12:59:55 +0200 Subject: [PATCH] leds: turris-omnia: change max brightness from 255 to 1 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using binary brightness makes more sense for this controller, because internally in the MCU it works that way: the LED has a color, and a state whether it is ON or OFF. The resulting brightness computation with led_mc_calc_color_components() will now always result in either (0, 0, 0) or the multi_intensity value.
