Quick Start
User Software
The LMP92066EVM GUI application software is available as a download from the Texas Instruments
website (
). With this software and the USB2Any interface dongle the user will be able to fully
exercise the functionality of the LMP92066, including:
•
Read and Write operations from and to internal registers of the LMP92066.
•
Control the DRVENx inputs of the LMP92066.
•
Write data into the internal EEPROM.
•
Plot and log, in real time, the Temperature Sensor output and DAC input data.
•
Plot and log the VDACx vs Temperature transfer function.

Quick Start
1.1
Software Installation
To install the LMP92066 EVM GUI, run the setup.exe, a self-extracting archive that will install all the
necessary components of the user application – this includes the LabView run-time environment. The
setup.exe will also install Python 2.7, if it is not already present in the target system.
1.2
Kit Assembly
The EVM mates directly to the USB2Any via the 30-pin dual row header. Note that the EVM header spans
the 3 headers on the USB2Any controller board.
After the boards are plugged in together, install the USB cable between the USB2Any and the host PC.
Ensure that the 3-pin selectors J3 through J10 are in the factory default positions – see diagrams in
and
for reference. The factory default set up establishes the device I

C slave address
that is expected by the GUI default settings. It also allows the kit to operate from the power supply offered
by the USB interface – no other power supplies are necessary at this point.
The figures below show the assembled kit for both enclosed and unenclosed versions of the USB2Any
controller. Note that the SUPPLY block is left open.
