My target platform is a TI ez430-RF2500 development board, which claims to only be able to pass up to Vcc=3.3v to the input of any given pin on the target board.

Does this mean I need some kind of boost or driver to connect the LCD Display via i2c? I've tried pulling the lines up to 5V, and it does ...

I'm trying to communicate with an LCD0821 display using I2C with my TI MSP430 microcontroller.

I was wondering what voltages levels the LCD0821 considers logical high and logical low, so I know what voltage I should pull the SCL and SDA lines to. This doesn't seem to be specified in the datasheets ...
