@defgroup pfleury_ic2master I2C Master library
@code #include <i2cmaster.h> @endcode
@brief I2C (TWI) Master Software Library
Basic routines for communicating with I2C slave devices. This single master
implementation is limited to one bus master on the I2C bus.
This I2c library is implemented as a compact assembler software implementation of the I2C protocol
which runs on any AVR (i2cmaster.S) and as a TWI hardware interface for all AVR with built-in TWI hardware (twimaster.c).
Since the API for these two implementations is exactly the same, an application can be linked either against the
software I2C implementation or the hardware I2C implementation.
Use 4.7k pull-up resistor on the SDA and SCL pin.
Adapt the SCL and SDA port and pin definitions and eventually the delay routine in the module
i2cmaster.S to your target when using the software I2C implementation !
Adjust the CPU clock frequence F_CPU in twimaster.c or in the Makfile when using the TWI hardware implementaion.
@note
The module i2cmaster.S is based on the Atmel Application Note AVR300, corrected and adapted
to GNU assembler and AVR-GCC C call interface.
Replaced the incorrect quarter period delays found in AVR300 with
half period delays.
@author Peter Fleury pfleury@gmx.ch http://jump.to/fleury
@par API Usage Example
The following code shows typical usage of this library, see example test_i2cmaster.c
@code
#include <i2cmaster.h>
#define Dev24C02 0xA2 // device address of EEPROM 24C02, see datasheet
int main(void)
{

i2c_init(); // initialize I2C library
// write 0x75 to EEPROM address 5 (Byte Write)
i2c_start_wait(Dev24C02+I2C_WRITE); // set device address and write mode
i2c_write(0x05); // write address = 5
i2c_write(0x75); // write value 0x75 to EEPROM
i2c_stop(); // set stop conditon = release bus
// read previously written value back from EEPROM address 5
i2c_start_wait(Dev24C02+I2C_WRITE); // set device address and write mode
i2c_write(0x05); // write address = 5
i2c_rep_start(Dev24C02+I2C_READ); // set device address and read mode

# ErgoDox EZ Utilities
The Python script in this directory, by [mbarkhau](https://github.com/mbarkhau) allows you to write out a basic ErgoDox EZ keymap using Markdown notation, and then transpile it to C, which you can then compile. It's experimental, but if you're not comfortable using C, it's a nice option.

# ErgoDox EZ Default Configuration
## Changelog
* Feb 2, 2016 (V1.1):
* Made the right-hand quote key double as Cmd/Win on hold. So you get ' when you tap it, " when you tap it with Shift, and Cmd or Win when you hold it. You can then use it as a modifier, or just press and hold it for a moment (and then let go) to send a single Cmd or Win keystroke (handy for opening the Start menu on Windows).
This is what we ship with out of the factory. :) The image says it all:

# The Easy Way
If you can find firmware someone else has made that does what you want, that
is the easiest way to customize your ErgoDox. It requires no programming
experience or the setup of a build environment.
Quickstart:
- Find and download an existing firmware
[from Other Firmware Options](#other-firmware-options)
- Then flash the firmware to your [ErgoDox Ez](#ergodox-ez)
or [ErgoDox Infinity](#ergodox-infinity)
# Customizing Keymaps
There are many existing keymaps in the "keymaps" directory. If you just want
to use one of them, you don't need to modify keymaps and can just build and
flash the firmware as described below. These directories each have a
"readme.md" file which describe them.
If none of the existing keymaps suit you, you can create your own custom
keymap. This will require some experience with coding. Follow these steps
to customize a keymap:
- Read the [qmk firmware README](https://github.com/jackhumbert/qmk_firmware) from top to bottom. Then come back here. :)
- Clone the qmk_firmware repository
- Set up your build environment (see below).
- Make a new directory under "keymaps" to hold your customizations.
- Copy an existing keymap that is close to what you want, such as
"keymaps/default/keymap.c".
- Use an editor to modify the new "keymap.c". See "Finding the keycodes you
need" below). Try to edit the comments as well, so the "text graphics"
represent your layout correctly.
- Compile your new firmware (see below)
- Flash your firmware (see below)
- Test the changes.
- Submit your keymap as a pull request to the qmk_firmware repository so
others can use it. You will want to add a "readme.md" that describes the
keymap.
# Build Dependencies
Before you can build, you will need the build dependencies. There is a script
to try to do this for Linux:
- Run the `util/install_dependencies.sh` script as root.
For the Infinity, you need the chibios submodules to be checked out or you
will receive errors about the build process being unable to find the chibios
files. Check them out with:
- Go to the top level repo directory and run: `git submodule update --init --recursive`
# Flashing Firmware
## ErgoDox Ez
The Ez uses the [Teensy Loader](https://www.pjrc.com/teensy/loader.html).
Linux users need to modify udev rules as described on the Teensy Linux page.
Some distributions provide a binary, maybe called `teensy-loader-cli`).
To flash the firmware:
- Build the firmware with `make keymapname`, for example `make default`
- This will result in a hex file called `ergodox_ez_keymapname.hex`, e.g.
`ergodox_ez_default.hex`
- Start the teensy loader.
- Load the .hex file into it.
- Press the Reset button by inserting a paperclip gently into the reset hole
in the top right corder.
- Click the button in the Teensy app to download the firmware.
## ErgoDox Infinity
The Infinity is two completely independent keyboards, and needs to be flashed
for the left and right halves seperately. To flash them:
- Build the firmware with `make infinity-keymapname`
- Plug in the left hand keyboard only.
- Press the program button (back of keyboard, above thumb pad).
- Install the firmware with `sudo make infinity-keymapname-dfu-util`
- Build left hand firmware with `make infinity-keymapname MASTER=right`
- Plug in the right hand keyboard only.
- Press the program button (back of keyboard, above thumb pad).
- Install the firmware with `sudo make infinity-keymapname-dfu-util MASTER=right`
More information on the Infinity firmware is available in the [TMK/chibios for
Input Club Infinity Ergodox](https://github.com/fredizzimo/infinity_ergodox/blob/master/README.md)
### Infinity Master/Two Halves
The Infinity is two completely independent keyboards, that can connect together.
You have a few options in how you flash the firmware:
- Flash the left half, rebuild the firmware with "MASTER=right" and then flash
the right half. This allows you to plug in either half directly to the
computer and is what the above instructions do.
- Flash the left half, then flash the same firmware on the right. This only
works when the left half is plugged directly to the computer and the keymap
is mirrored. It saves the small extra step of rebuilding with
"MASTER=right".
- The same as the previous one but with "MASTER=right" when you build the
firmware, then flash the same firmware to both halves. You just have to
directly connect the right half to the computer.
- For minor changes such as changing only the keymap without having updated
any part of the firmware code itself, you can program only the MASTER half.
It is safest to program both halves though.
# Contributing your keymap
The QMK firmware is open-source, so it would be wonderful to have your contribution! Within a very short time after launching we already amassed dozens of user-contributed keymaps, with all sorts of creative improvements and tweaks. This is very valuable for people who aren't comfortable coding, but do want to customize their ErgoDox. To make it easy for these people to use your layout, I recommend submitting your PR in the following format.
1. All work goes inside your keymap subdirectory (`keymaps/german` in this example).
2. `keymap.c` - this is your actual keymap file; please update the ASCII comments in the file so they correspond with what you did.
3. `readme.md` - a readme file, which GitHub would display by default when people go to your directory. Explain what's different about your keymap, what you tweaked or how it works. No specific format to follow, just communicate what you did. :)
4. Any graphics you wish to add. This is absolutely not a must. If you feel like it, you can use [Keyboard Layout Editor](http://keyboard-layout-editor.com) to make something and grab a screenshot, but it's really not a must. If you do have graphics, your readme can just embed the graphic as a link, just like I did with the default layout.
# Finding the keycodes you need
Let's say you want a certain key in your layout to send a colon; to figure out what keycode to use to make it do that, you're going to need `quantum/keymap_common.h`.
That file contains a big list of all of the special, fancy keys (like, being able to send % on its own and whatnot).
If you want to send a plain vanilla key, you can look up its code under `doc/keycode.txt`. That's where all the boring keys hang out.
# Other Firmware Options
There are external tools for customizing the layout, but those do not use
the featurs of this qmk firmware. These sites include:
- [Massdrop configurator](https://keyboard-configurator.massdrop.com/ext/ergodox) for Ez
- [Input Club configurator](https://input.club/configurator-ergodox) for Infinity, provides left and right files
You can also find an existing firmware that you like, for example from:
- [Dozens of community-contributed keymaps](http://qmk.fm/keyboards/ergodox/)
This qmk firmware also provides the ability to customize keymaps, but requires
a toolchain to build the firmware. See below for instructions on building
firmware and customizing keymaps.
