MSP432E411Y: MSP432E411Y

Part Number: MSP432E411Y
Other Parts Discussed in Thread: MSP432E401Y

I m trying to read 2 bytes from a I2C slave device using MSP432E411Y in polling mode. some times the data i receive is invalid. when monitored the I2C waveform from MSP432E411Y, i see few times the clock state would have changed in the unexpected places. Because of which the data from slave device is not correct. I have also seen many posts where people are facing issue with the I2C driver on MSP432E411Y.

Can some one share a properly working I2C master code to read 2 bytes from slave device consistently?

Thanks in advance..

Hello Arathi,

Did you look at the following example: ./examples/rtos/MSP_EXP432E401Y/drivers/i2ctmp116/?

Thanks,
Sai

Thanks Sai for reply.

I m looking for code with out RTOS ( using MAP_I2CMasterDataPut() and similar function calls)

Arathi,

The no RTOS examples are in the folder ./examples/nortos/MSP_EXP432E401Y/driverlib/ of the SimpleLink MSP432E4 SDK. Look for the I2C examples in this folder.

Even though these examples are built for the MSP432E401Y MCU, these examples should also work with the MSP432E411Y MCU.

Thanks,
Sai
