MSP432P401R: Cant communicate over I2C, attempting between MSP430 and MSP432

Connor Fitzsimmons

Part Number: MSP432P401R

Hello, i have been trying to communicate between the MSP432 and a sensor using energia but couldnt get that working, so i thought i should try the example CSS projects but i dont think the examples for the MSP430 slave i2c and the MSP432 master i2c are compatible. I dont have another MSP432 to do the i2c test on. Is there something i may be able to do, like trying to use the MSP432 code on the MSP430?

Hi, Connor,

It is not good to use the MSP432 code on MSP430. They are different platform: the core is different.

Why you don't try the MSP432 I2C master code example to communicate with MSP430 with its I2C slave code example? Please note the I2C speed needs to be set to the same. It should be no problem for them to communicate successfully.

Thanks,

Lixin
