+
+ @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();

any part of the firmware code itself, you can program only the MASTER half.
It is safest to program both halves though.
+## ErgoDone
+
+The ErgoDone uses its own HID bootloader and needs to be flashed using the [TKG Toolkit](https://github.com/kairyu/tkg-toolkit).
+
+ - Build the firmware with `make ergodone-keymapname`
+
+ - While plugging in the USB cable, hold the two right-most keys on the left half of the ErgoDone to enter FLASH mode.
+
+ - Use the utility from [TKG Toolkit](https://github.com/kairyu/tkg-toolkit) to flash the keyboard: `hid_bootloader_cli -mmcu=atmega32u4 ergodox_ergodone_keymapname.hex`

# 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.
