CCS/MSP430FR2676: Communication and API

Hallo user6167124

the question is quite generic and I assume you are going to use the FR2676 device as a Slave, having the ESP actng as Master.

Let me start with some basic info about I2C itself and also related to CapTIvate devices.

On the CapTIvate Design Center, if you double click on the MSPFR2676 icon you can define the communication interface (UART, Bulk_I2C etc.)

this setting will automatically include in the SW the necessary modules for this communication.

Please check also the CapTIvate Technology Guide for additional examples (search for I2C)

The Application note given below, is a generic I2C document

In the users guide  Chapter24

There are also older threads in the E2E forum which gives additional information. For example

Please check also in the DS the I2C related pins for your device.

I would suggest to create a simple project in the CapTIvate Design Center (just one button), generate the code with the I2C communication selected and try to establish the I2C communication with the ESP.

Please let me know if that helps
