* Make solo half of split keyboards (more) usable. (#13523)Joakim Tufvegren2021-08-221-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make solo half of split keyboards (more) usable. Using only one half of a split keyboard (that's using the split_common framework to communicate) is not a great experience, since several read timeouts per scan cycle cause an unusably slow scan rate. This change blocks all split communication attempts for 500 ms (configurable) after an error occurs, causing the scan rate to become at least _more_ usable, but might need some tweaking to work fully on most keyboards. One read timeout still needs to occur after the 500 ms has passed, and if that timeout isn't low enough, some scan cycles may still be too slow. * Fix lint complaint. * Require 25 consecutive comm errors to see comms as disconnected. The number of max errors can be overridden by defining `SPLIT_MAX_CONNECTION_ERRORS`. * Add comments to new defines, and ability to disable disconnection check. Also increase `SPLIT_MAX_CONNECTION_ERRORS` to 40, since it's divisible by most relevant numbers for the description. * Make lint happy ...again * Only update `connection_check_timer` when needed. * Add new defines to split keyboard documentation. * Move connection timeout logic to transport.c, add `is_transport_connected`. * Use split_common disconnection logic in matrix.c. Instead of doing more or less the same thing twice. * Move disconnection logic to `transport_master`. Is a cleaner implementation, and causes the scan rate while disconnected to increase instead of decrease. * Lint fixes. * Lower default `SERIAL_USART_TIMEOUT` to 20 ms. The read timeout must be low enough to not cause exessively long scan cycles when using a solo split half. 10 ms was determined from testing to work fine even with the slowest defined baudrate of 19200 (5 ms was too low for that case), so 20 ms should be fine for most cases. * Remove `SERIAL_USART_TIMEOUT` from ergodox_infinity/config.h Was somewhat mistakenly included in an earlier PR. * Fix building with `USE_I2C`. * Reduce built firmware size. Not really sure why this works, the idea was taken from tzarc's work on split disconnection. * Tweak and improve opt-out for split disconnection logic. There are now two ways to opt out from this feature: * Set `SPLIT_MAX_CONNECTION_ERRORS` to 0. This will completely disable the connection status checks (also affects the slave matrix reset logic in matrix.c, though). * Set `SPLIT_CONNECTION_CHECK_TIMEOUT` to 0. This will only disable the communication throttling while disconnected. Will make the firmware smaller. * Make split disconnection logic work with custom transports. Includes a fallback implementation for keyboards using a custom split_util.c but not a custom matrix.c (currently no such keyboard seems to be merged, though). * Remove unnecessary include of timer.h Co-authored-by: Joel Challis <git@zvecr.com> Co-authored-by: Joel Challis <git@zvecr.com>

* Extensible split data sync (#11930)Nick Brassel2021-06-181-10/+104
| | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Add modifier state to the split keyboard transport (#10400)Casey Webster2020-12-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add modifier state to the split transport This adds modifier state to the i2c and serial transport for split keyboards. The purpose of this is to allow e.g. displaying modifier state on the slave side of a split keyboard on an oled. This adds one byte to the data transferred between halves. This also fixes a missing ifdef guard for BLACKLIGHT_ENABLE. Break modifiers into real/weak/oneshot Fix incorrect slave serial mod setting Fix typo in serial weal mod setter Fix build errors for the I2C code that I introduced Code cleanup and formatting per project preferences Correctly get oneshot mods Fix missing braces Remove unneeded ifdef guard Make the added state transport optional Add documentation for the new define to enable this feature Fix stray grave mark * Fix error introduced in conflict resolution
