This guide details the use of the TDC7201-ZAX-EVM Evaluation Module (referred to as TDC7201EVM for
the remainder of this document). The TDC7201EVM is an evaluation module that allows users to evaluate
the operation and performance of the TDC7201 Time-to-Digital Converter. One example application that
requires accurate time-to-digital conversion is LIDAR.
The TDC7201EVM connects to the MSP430 LaunchPad evaluation kit for capturing data, and it connects
to a user-friendly Graphic User Interface (GUI) to modify the registers and display the data.
