Detailed Description

Software driver functions for I2C and MKII boosterpack.

Light and temperature sensors on MKII
https://www.ti.com/tool/BOOSTXL-EDUMKII
The TMP006 was discontinued in 2017. Therefore, it is no longer populated on the board. Documentation of the TMP006 is unchanged in this user's guide to accommodate users who still have the device populated on the board

Version: ECE319K v1.0
