I2C Debugging on MSP430

Other Parts Discussed in Thread: MSP430F5229

Hi,

I am trying to set up an I2c connection to an LCD display.  I am using the MSP430F5229 on the MSP-EXP430F5229 development board.

I built the following master examples from TI:

MSP430F55xx_uscib0_i2c_06.c (continuously transmits 0x00,0x01,...,0xff)

MSP430F55xx_uscib0_i2c_08.c (continuously transmits an 0x11,0x22,...0x55 array)

But when I run them on the board, I see no output on my oscilloscope.

I am probing pins 3.0 and 3.1, and I have 10K pull-ups connected to the VCC (3.3V) line on the development board.

Could someone help me track down what I am missing?  I just want to make sure I'm outputting data in the appropriate port at the speed I want.

Thanks,

Dante
