* Fix dirtying in oled_write_pixel() Set the dirty bit for the block only if oled_write_pixel() actually changed the buffer state. Without this check oled_write_pixel() could not be used inside the oled_task_user() code using the “redraw always” style, because the blocks touched by oled_write_pixel() would always appear dirty, and oled_render() would not proceed beyond the first such dirty block. * Fix oled_write_pixel() with 90/270 degree rotation Use oled_rotation_width instead of OLED_DISPLAY_WIDTH, so that a rotated display would be handled correctly. * Fix compilation with custom OLED_BLOCK_COUNT and OLED_BLOCK_SIZE Some OLED sizes (e.g., 64×48) may require a nonstandard value of OLED_BLOCK_COUNT. The documentation says that this value may be redefined in config.h, but actually trying to redefine it caused a compile error, because the macro was redefined in oled_driver.c. Make the OLED_BLOCK_COUNT definition in oled_driver.c respect any user override, and do the same for OLED_BLOCK_SIZE just in case. * Fix handling of out-of-range bits in oled_dirty If a custom OLED_BLOCK_COUNT value is specified, some bits in oled_dirty may not correspond to existing blocks; however, if those bits are set somewhere (e.g., by code with sets oled_dirty to ~0 or even -1), oled_render() would try to handle them and could access memory beyond oled_buffer and perform hardware operations with out of range values. Prevent this by masking off unused bits in oled_render(), and also avoid setting those bits in other functions. * Fix potentially wrong dirtying in oled_write_char() oled_write_char() tried to mark the position just beyond the written character as dirty; use (OLED_FONT_WIDTH - 1) to dirty the last position still belonging to the character instead. * Fix `#define OLED_BLOCK_TYPE uint32_t` on AVR Using uint32_t as OLED_BLOCK_TYPE did not work properly on AVR, because some bit shifts were performed using 16-bit int. Add explicit casts to OLED_BLOCK_TYPE to those shifts.
Quantum Mechanical Keyboard Firmware
This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.
Documentation
The docs are powered by Docsify and hosted on GitHub. They are also viewable offline; see Previewing the Documentation for more details.
You can request changes by making a fork and opening a pull request, or by clicking the "Edit this page" link at the bottom of any page.
Supported Keyboards
The project also includes community support for lots of other keyboards.
Maintainers
QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.
Official Website
qmk.fm is the official website of QMK, where you can find links to this page, the documentation, and the keyboards supported by QMK.
