-**I2C on the MSP430G2553**
-All driver files are from the [[https://home.hccnet.nl/willem.ouwerkerk/egel-for-msp430/egel%20for%20launchpad.html#e03x|Egel Project, from chapter 30ff]]. This code example works with all added driver versions of the noForth I2C implementation:
-<code>
-\ Example with clock & 24C32 EEPROM
-: {EEADDR   ( a +n -- )                     \ Address EEprom
-device!  {i2c-write  b-b bus! bus! ;
-\ Read data b from 24C32 EEPROM byte-address addr.
-: EC@       ( addr -- b )
-{eeaddr i2c}  1 {i2c-read bus@ i2c} ;
-\ Write data b to 24C32 EEPROM byte-address addr.
-: EC!       ( b addr -- )
-{eeaddr  bus! i2c}  {poll} ;
-</code>
