O, a przegapiłem wczorajszy update, ważniejszy wydaje się:
- USB Sticks are now mounting a way faster at power up ! :)
- I2C LCD display support added !
These kind of I2C LCD board is compatible with the firmware :

(board only - without the LCD)

(board + LCD)

(board + LCD)
Any I2C address is supported : The firmware scan automatically the I2C bus at power up (0x20-0x27 and 0x38-0x3F address range scanned)
So there is no specific requirement about the I2C address setting.
To connect the I2C LCD, you have to connect SDA & SCL at the J7 connector (see below).
Please note that 2 additionnals 4.7Kohms pull up resistors (+5V) are needed on SCL & SDA.
the +5V and GND wire can be connected on the programming connector (see below) :
If you want to build the I2C board yourself, here is the schematic:
