I2C for noForth on the MSP430

I2C on the MSP430G2553

All driver files are from the Egel Project, from chapter 30ff. This code example works with all added driver versions of the noForth I2C implementation:

\ Example with clock & 24C32 EEPROM
: {EEADDR   ( a +n -- )                     \ Address EEprom
    50 device!  {i2c-write  b-b bus! bus! ;

\ Read data b from 24C32 EEPROM byte-address addr. 
: EC@       ( addr -- b )
    2 {eeaddr i2c}  1 {i2c-read bus@ i2c} ;

\ Write data b to 24C32 EEPROM byte-address addr.
: EC!       ( b addr -- )
    3 {eeaddr  bus! i2c}  {poll} ;
