Simplify split_common Code significantly (#4772) * Eliminate separate slave loop Both master and slave run the standard keyboard_task main loop now. * Refactor i2c/serial specific code Simplify some of the preprocessor mess by using common function names. * Fix missing #endif * Move direct pin mapping support from miniaxe to split_common For boards with more pins than sense--sorry, switches. * Reordering and reformatting only * Don't run matrix_scan_quantum on slave side * Clean up the offset/slaveOffset calculations * Cut undebounced matrix size in half * Refactor debouncing * Minor fixups * Split split_common transport and debounce code into their own files Can now be replaced with custom versions per keyboard using CUSTOM_TRANSPORT = yes and CUSTOM_DEBOUNCE = yes * Refactor debounce for non-split keyboards too * Update handwired/xealous to build using new split_common * Fix debounce breaking basic test * Dodgy method to allow a split kb to only include one of i2c/serial SPLIT_TRANSPORT = serial or SPLIT_TRANSPORT = i2c will include only that driver code in the binary. SPLIT_TRANSPORT = custom (or anything else) will include neither, the keyboard must supply it's own code if SPLIT_TRANSPORT is not defined then the original behaviour (include both avr i2c and serial code) is maintained. This could be better but it would require explicitly updating all the existing split keyboards. * Enable LTO to get lets_split/sockets under the line * Add docs for SPLIT_TRANSPORT, CUSTOM_MATRIX, CUSTOM_DEBOUNCE * Remove avr-specific sei() from split matrix_setup Not needed now that slave doesn't have a separate main loop. Both sides (on avr) call sei() in lufa's main() after exiting keyboard_setup(). * Fix QUANTUM_LIB_SRC references and simplify SPLIT_TRANSPORT. * Add comments and fix formatting.

Make solo half of split keyboards (more) usable. (#13523) * 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>
