MSP432E401Y: I2C Connection Pins

Ryan Pond

Part Number: MSP432E401Y

Hi,

I recently bought an Adafruit Color Sensor, and I want to connect it to my TI board. I have connected the SCL and SDA pins on the Sensor to the boards PD0 and PD1 pins (respectively) since I believe those are equivalent for the I2C that is built into the board. Is this the right connection to access the I2C SCL and SDA inputs? And, is there a code example that I can look at? All I want to do is take a reading from the sensor.

Thanks for the help in advance.

Hello Ryan,

I have no time to check your pin connections.

Be careful, read twice, check twice and will be O.K.

Links to excellent I2C examples you will find using Resource Explorer:

Hello Ryan,

In addition to the examples that Tomasz has pointed out, you can refer the correct pin outs in the Datasheet and look for "GPIO Pin Multiplexing" sub-section.

Thanks,
Sai
