I succeed interfacing a 16x2 LCD with a 430G2553 trough a PCF8574A port expansor as I2C/parallel converter using the DFRobot.com library posted by Fmilburn, after solving the Energia 18 known issue with the 2553 I2C pin association described here. To do this, it iwas necessary to copy the files twi.c and twi_sw.c in the folder hardware/msp430/cores/msp430 in the Energia installation and, in addition to that, to edit the .cpp file in the library to add the line "Wire.setModule(0);" just before "Wire.begin(0);". Two additional comments that could be usefull for those that could want to use
