From 172e6a703041363decd6fc829542f33180c13beb Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Fri, 18 Jun 2021 09:10:06 +1000 Subject: Extensible split data sync (#11930) * Extensible split data sync capability through transactions. - Split common transport has been split up between the transport layer and data layer. - Split "transactions" model used, with convergence between I2C and serial data definitions. - Slave matrix "generation count" is used to determine if the full slave matrix needs to be retrieved. - Encoders get the same "generation count" treatment. - All other blocks of data are synchronised when a change is detected. - All transmissions have a globally-configurable deadline before a transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms). - Added atomicity for all core-synced data, preventing partial updates - Added retries to AVR i2c_master's i2c_start, to minimise the number of failed transactions when interrupts are disabled on the slave due to atomicity checks. - Some keyboards have had slight modifications made in order to ensure that they still build due to firmware size restrictions. * Fixup LED_MATRIX compile. * Parameterise ERROR_DISCONNECT_COUNT. --- quantum/split_common/transport.h | 165 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 165 insertions(+) (limited to 'quantum/split_common/transport.h') diff --git a/quantum/split_common/transport.h b/quantum/split_common/transport.h index a9f66301bf..2e07f6b25c 100644 --- a/quantum/split_common/transport.h +++ b/quantum/split_common/transport.h @@ -1,10 +1,175 @@ +/* Copyright 2021 QMK + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
