This library is based on work of Ben Zijstra and Heiko/Hkipnik

The library supports the SSD1306 graphical LCD in I2C mode.

Since the display can not read data back, the library supports only the graphical write statements. Commands like LINE, PSET and CIRCLE which need to alter a single pixel are not supported.

 

 

XMEGA

For use with XMEGA you need to define 2 constants in your code.

const TWI_ADR = interface

const TWI_CH = num

 

The interface must point to the TWI control register, this could be :  TWIC_CTRL but aldo TWID_CTRL, TWIE_CTRL and TWIF_CTRL

The TWI_CH constant with the value num, must be 1 for TWIC, 2 for TWID, 4 for TWIE and 8 for TWIF

The reference to : $lib "i2c_twi.lbx" must be removed.
