Hello,
I want to connect my MSP-EXP430F5529LP ("MSP430") LaunchPad to an external device via I2C.
Which I2C port should I use?
(1) The MSP430 Quick Start Guide (slau536.pdf) includes a diagram of the BoosterPack connector showing two sets of I2C ports:
-set#1-
I2C - SCL - PM_UCB1SOMI - PM_UCB1SCL - P4.2
I2C - SDA - PM_UCB1SIMO - PM_UCB1SDA - P4.1
-set#2-
UCB0SDA - UCB0SIMO - P3.0
UCB0SCL - UCB0SOMI - P3.1
(2) I am using the sample project, usci_b_i2c_ex3_masterTxSingle.c.
