@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)
{
unsigned char ret;
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
ret = i2c_readNak(); // read one byte from EEPROM
i2c_stop();

/*
Note to self: adapted from ergodox EZ matrix
The "column" and "row" in here actually refers to the opposite on the keyboard
see definition of KEYMAP in v1.h, the grid is transposed so that a "row" in here is actually a "column" on the physical keyboard
Nicolas
Note for ErgoDox EZ customizers: Here be dragons!
This is not a file you want to be messing with.
All of the interesting stuff for you is under keymaps/ :)

# Frenchdev : My take on a splitted keyboard for dev and french language
Concept based on
- [ergodox](https://ergodox-ez.com/)
- [katy](https://deskthority.net/workshop-f7/katy-keyboard-or-k80cs-key80-contoured-split-t8524.html)
with the added possibility to connect up to 6 external switches like pedals,
and somewhat like the katy, not all keys are on the same level for easier reach.
###Photos

- [editable layout on keyboard layout editor](http://www.keyboard-layout-editor.com/#/gists/4480e3ab8026eb7c710a7e22203ef4aa) (keys placement is NOT precise on this)
- [the thing when finished](http://imgur.com/a/6FY8v)
- [concept and cardboard mockup](http://imgur.com/a/R0vvs)
##Build instructions
docker run --rm -e keymap=default -e keyboard=frenchdev --rm -v D:/Repositories/qmk:/qmk:rw edasque/qmk_firmware
##Laser-cuttable file
There is intentionnaly no hole for the TRRS connector, you are supposed to use a drill for it.
This way if you don't want to use the pedals you don't have a useless hole. Plus it's cleaner.

##Side stickers
You can find my original file here : http://qmk.fm/frenchdev/example_printable_stickers.svg
I used it when training but now I use blanks and the layout is different.
I still uploaded it because I think it can be a good jumpstart for any temporary stickers on the
side of keycaps.
##List of parts
- I2C mcp23018
- [teensy 2](https://www.pjrc.com/store/teensy.html)
- 3 LED, 5mm tall with flat head
- 3 330 ohm resistor
- 2 470 ohm resistor
- 2 TRRS connectors
- 1 [micro usb breakout board](http://www.ebay.com/itm/-/201387922085?)
- 88 cherry/gateron switchs
- 94 4148 diodes
- 34 R4 keys
- 14 R3 keys
- 20 R2 keys
- 22 R1 keys
if you fancy adding pedals :
[these are good enough and cheap](https://www.amazon.fr/gp/product/B00V7WITKI/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1). You also need a RCA connector for each of those to replace the included cable
If you (or your coworkers) find them too loud you can replace the switch inside them.
For once we don't really care about what's inside :)
##Various indications
The PHYSICAL rows and columns are connected as such :

`------------------'
We use pull up resistor for SCL and VDA, see https://github.com/ErgoDox-EZ/docs/blob/master/ErgoDox%20EZ%20Schematic.pdf for example
the connector is a standard TRRS (jack with audio + mic)
Diode direction is row to column
