We started with the [QMK firmware](https://github.com/qmk/qmk_firmware), a heavily modified fork of [TMK](https://github.com/tmk/tmk_keyboard). -# Build -- [[FAQ/Build]] +## What Differences Are There Between QMK and TMK? +TMK was originally designed and implemented by [Jun Wako](https://github.com/tmk). QMK started as [Jack Humbert's](https://github.com/jackhumbert) fork of TMK for the Planck. After a while Jack's fork had diverged quite a bit from TMK, and in 2015 Jack decided to rename his fork to QMK. -# Keymap -- [[FAQ/Keymap]] +From a technical standpoint QMK builds upon TMK by adding several new features. Most notably QMK has expanded the number of available keycodes and uses these to implement advanced features like `S()`, `LCTL()`, and `MO()`. You can see a complete list of these keycodes in [Quantum Keycodes](quantum_keycodes.html). +From a project and community management standpoint TMK maintains all the officially supported keyboards by himself, with a bit of community support. Separate community maintained forks exist or can be created for other keyboards. Only a few keymaps are provided by default, so users typically don't share keymaps with each other. QMK encourages sharing of both keyboards and keymaps through a centrally managed repository, accepting all pull requests that follows the quality standards. These are mostly community maintained, but the QMK team also helps when necessary. + +Both approaches have their merits and their drawbacks, and code flows freely between TMK and QMK when it makes sense. # Debug Console ## hid_listen can't recognize device When debug console of your device is not ready you will see like this: - Waiting for device:......... +``` +Waiting for device:......... +``` once the device is pluged in then *hid_listen* finds it you will get this message: - Waiting for new device:......................... - Listening: +``` +Waiting for new device:......................... +Listening: +``` -Check if you can't get this 'Listening:' message: -- build with `CONSOLE_ENABLE=yes` in **Makefile**. +If you can't get this 'Listening:' message try building with `CONSOLE_ENABLE=yes` in [Makefile] You may need privilege to access the device on OS like Linux. - try `sudo hid_listen` @@ -73,41 +77,13 @@ Without reset circuit you will have inconsistent reuslt due to improper initiali ## Can't read column of matrix beyond 16 -Use `1UL<<16` instead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16. +Use `1UL<<16` instead of `1<<16` in `read_cols()` in [matrix.h] when your columns goes beyond 16. -In C `1` means one of **int** type which is **16bit** in case of AVR so you can't shift left more than 15.
