 # Teensy LC, 3.0, 3.1, 3.2 support

 These ARM Teensies are now supported through [ChibiOS](http://chibios.org).

 You'll need to install an ARM toolchain, for instance from [gcc ARM embedded](https://launchpad.net/gcc-arm-embedded) website, or using your favourite package manager. After installing, you should be able to run `arm-none-eabi-gcc -v` in the command prompt and get sensible output. This toolchain is used instead of `avr-gcc`, which is only for AVR chips. Naturally you'll also need the usual development tools (e.g. `make`), just as in the AVR setting.

 Next, you'll need ChibiOS. For Teensies, you'll need code from two repositories: [chibios-main](https://github.com/ChibiOS/ChibiOS) and [chibios-contrib](https://github.com/ChibiOS/ChibiOS). If you're not using git, you can just download a [zip of chibios from here](https://github.com/ChibiOS/ChibiOS/archive/a7df9a891067621e8e1a5c2a2c0ceada82403afe.zip), unpack the zip, and rename/move the unpacked directory (named `ChibiOS-<long_hash_here>`) to `tmk_core/tool/chibios/chibios` (so that the file `tmk_core/tool/chibios/chibios/license.txt` exists). Now the same procedure with a [zip of chibios-contrib from here](https://github.com/ChibiOS/ChibiOS-Contrib/archive/e1311c4db6cd366cf760673f769e925741ac0ad3.zip): unpack and move `ChibiOS-Contrib-<long_hash_here>` to `tmk_core/tool/chibios/chibios-contrib`.

 (If you're using git, you can just clone the two repos: [chibios](https://github.com/ChibiOS/ChibiOS) and [chibios-contrib](https://github.com/ChibiOS/ChibiOS-Contrib). However - be warned that things may be somewhat out-of-sync (updates at different rates), so you may need to hunt a bit for the right commits.)

 (Why do we need chibios-contrib? Well, the main repo focuses on STM32 chips, and Freescale/NXP Kinetis chips are supported via the Contrib repository.)

 This should be it. Running `make` in `keyboard/teensy_lc_onekey` should create a working firmware in `build/`, called `ch.hex`.

 For more notes about the ChibiOS backend in TMK, see `tmk_core/protocol/chibios/README.md`.

 ## About this onekey example

 It's set up for Teensy LC. To use 3.x, you'll need to edit the `Makefile` (and comment out one line in `mcuconf.h`). A sample makefile for Teensy 3.0 is provided as `Makefile.3.0`, can be used without renaming with `make -f Makefile.3.0`. Similarly for Teensy 3.2, there's `Makefile.3.2`.

 ## Credits

 TMK itself is written by hasu, original sources [here](https://github.com/tmk/tmk_keyboard).

 The USB support for Kinetis MCUs is due to RedoX. His ChibiOS fork is also [on github](https://github.com/RedoXyde/ChibiOS); but it doesn't include Teensy LC definitions.

 ## Features that are not implemented yet

 Currently only the more fancy suspend features are not there (power saving during suspend). The rest should work fine (reports either way are welcome).

 # Matrix programming notes

 The notes below explain what commands can be used to examine and set the status of Teensy pins.

 ## ChibiOS pin manipulation basics

 ### Pins

 Each pin sits on a "port", each of which comprises at most 32 individual pins.
 So for instance "PTC5" from Kinetis manual/datasheet refers to port C (or GPIOA), pin 5. Most functions dealing with pins take 2 parameters which specify the pin -- the first being the port, the second being the pin number.

 Within ChibiOS, there are definitions which simplify this a bit for the Teensies. `TEENSY_PINn_IOPORT` represents the port of the MCU's pin connected Teensy's PIN `n`, and `TEENSY_PINn` represents its MCU's pin number.

 ### Mode

 A MCU pin can be in several modes. The basic command to set a pin mode is

 palSetPadMode(TEENSY_PINn_IOPORT, TEENSY_PINn, PAL_MODE_INPUT_PULLUP);

 The last parameter is the mode. For keyboards, the usual ones that are used are `PAL_MODE_INPUT_PULLUP` (input with a pullup), `PAL_MODE_INPUT_PULLDOWN` (input with a pulldown), `PAL_MODE_INPUT` (input floating, a.k.a. Hi-Z), `PAL_MODE_OUTPUT_PUSHPULL` (output in the Arduino sense -- can be then set HIGH or LOW).

 ### Setting

 Pins are set HIGH (after they've been put into `OUTPUT_PUSHPULL` mode) by

 palSetPad(TEENSY_PINn_IOPORT, TEENSY_PINn);

 or set LOW by

 palClearPad(TEENSY_PINn_IOPORT, TEENSY_PINn);

 Toggling can be done with

 palTogglePad(TEENSY_PINn_IOPORT, TEENSY_PINn);

 Alternatively, you can use

 palWritePad(TEENSY_PINn_IOPORT, TEENSY_PINn, bit);

 where `bit` is either `PAL_LOW` or `PAL_HIGH` (i.e. `0` or `1`).

 ### Reading

 Reading pin status is done with

 palReadPad(TEENSY_PINn_IOPORT, TEENSY_PINn);

 The function returns either `PAL_HIGH` (actually `1`) or `PAL_LOW` (actually `0`).

 ### Further docs

 All the commands that are available for pin manipulation through ChibiOS HAL are documented in [ChibiOS PAL driver docs](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html).
