From fdd0f915271f79b104aa5d216566bcc3fd134e85 Mon Sep 17 00:00:00 2001 From: yiancar Date: Tue, 28 Aug 2018 16:03:11 +0300 Subject: ISSI31FL3733 driver (#3679) * ISSI31FL3733 driver - Addapted IS31 driver for the above driver * fix my branch * ISSI31FL3733 driver - Inclusion of above ISSI led driver * IS31fl3733 driver - Added correct function for control registers * Finalized support for ISSI31fl3733 led driver - Finalized and tested driver. - Modified i2c_master for arm due to declaration mistake. - Fixed spaces/tabs in quantum.h file. - Fixed spaces/tabs in common_features.mk file. - Removed unnecessary includes from rgb_matrix.c file. - Added local definitions for MIN and MAX macros in rgb_matrix.c file. - Adjusted chevron effect. - Added necessary define (RGB_3733_MATRIX_ENABLE) for makefile. - Added necessary C define (ISSI3733) to aid with inclusion of the correct header file. - Added documentation for the new driver. * Driver structure update - Changed rule includes to be more condensed (RGB_MATRIX_ENABLE = IS31FL3731) and (RGB_MATRIX_ENABLE = IS31FL3733) - Updated documentation - Reverted to the use of differently named functions for each driver and selecting the needed ones within rgb_matrix.c * ISSI Drivers refractoring - Moved issi drivers in a dedicated folder - Updated documentation * I2C library fix I released the special pins incorrectly before. It is now fixed. --- docs/feature_rgb_matrix.md | 52 ++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 50 insertions(+), 2 deletions(-) (limited to 'docs/feature_rgb_matrix.md') diff --git a/docs/feature_rgb_matrix.md b/docs/feature_rgb_matrix.md index ed33c7ea4..4f827f8dc 100644 --- a/docs/feature_rgb_matrix.md +++ b/docs/feature_rgb_matrix.md @@ -1,8 +1,12 @@ # RGB Matrix Lighting +## Driver configuration + +### IS31FL3731 + There is basic support for addressable RGB matrix lighting with the I2C IS31FL3731 RGB controller.
