2 Features and Specifications
The LEDMCUEVM-132 provides a host of features that allow it to be used with a variety of EVMs and for the
easy evaluation and debug of devices and systems.

•

A SPI bus that supports up to six devices is provided and is accessed via J6, J9, and J12 connectors. It
comes from the MCU (MSP432E401Y) through a digital isolator to the connectors. J12 can be used with
debug probes or can be mated to a connector that uses a standard 100-mil header.
There are two pairs of PWM signals (PWM1 + PWM2 and PWM3 + PWM4) that can be used for PWM
dimming of supported devices. These signals support up to 4 kHz operation and have the ability to be phase
shifted by 180 degrees. J12 is a standard 100-mil head that can either be used for probing or to mate with a
standard 100-mil connector.
Five GPIOs are provided and depending on the EVM selection the GPIOs are either enabled or disabled.
See the user's guide of the EVM for more details.
The MCU generates UART commands that are used by the TPS92662 lighting matrix manager device. The
single-ended communication is passed through a digital isolator and into a CAN transceiver to generate a
differential signal that is commonly used in noisy environments. Either the single-ended UART signals are
available via J4 header or the differential CAN signals are available by header J3.
There is an isolated 5-V supply that is created from the USB bus (5 V) and is supplied to the secondary side
to power the digital isolators, CAN transceivers, and is passed on to other EVMs as V-ISO. Not all EVMs use
this supply. Some have their own supplies separated from the LEDMCUEVM-133.
The LEDMCUEVM-133 supports firmware updates by the USB connection to the PC.
If the customer wants to develop their own firmware for the MSP432E401Y, then they have that ability to do
that by using J7 and the XDIS110 JTAG Debug Probe.
The MSP432E401Y can also be connected to the Emulator connections of an external MSP-EXP432E401Y
LaunchPad using J5.
The LEDMCUEVM-132 has a connection to the CAN bus of the MSP432 and it is also attached to a CAN
transceiver to generate a CAN signal. This hardware is not yet supported by the GUI.

5.2 MCU Control Window
The MCU Control window allows external control of the PWM dimming using the LEDMCUEVM-132 connections
to the attached EVM. PWM control is available for each channel with frequency and duty cycle control for
frequencies and duty cycles that are not covered by the register settings. It also allows for 180 degree phase
shift in between channels if desired. For example, if a PWM signal of 3 kHz was desired, they could use this
feature.
Figure 5-5. MCU Control (External PWM) Window
PWM 1 is the first PWM generator from the MCU and controls Duty Cycle 1 at PF2 pin of MCU and Duty Cycle
2 at PF3 pin of the MCU. PMW1-DutyCycle 1 coninsides with PWM_1 on the EVM and PWM1-DutyCycle 2
coninsides with PWM_2 of the EVM, see Figure 5-6. Furthermore, The PWM frequency of PMW 1 generator
is the same for both PWM_1 and PWM_2 and is seperate from PWM 2 generator, which controls PWM_3 and
PWM_4 on the EVM.
Figure 5-6. MCU Exnternal PWM for PWM_1 and PWM_2
PWM 2 is the second PWM generator from the MCU and controls Duty Cycle 1 at PG0 pin of the MCU and Duty
Cycle 2 at GP1 pin of the MCU. PWM 2 generator signals connects to PWM_3 (PG0) and PWM_4 (PG1) on the
attached EVM, see Figure 5-7.

There are times when specific register settings may want to be controlled directly instead of through the
simplified interface of the GUI. The following section is an example of doing reads and writes for when the
LEDMCUEVM-132 is connected to the TPS92520EVM-133 to ensure proper communications.

5.4 GUI Devices Window and Example Connections and Power Up
The device command window is the primary window that is different depending on which EVM is selected from
the drop-down menu from the EVM Selection and Setup window. Some selections allow you to choose more
than one device and a tab is created for each of the devices. The tab also shows the address number of the
device as "Addr x". The user's guide for each EVM should be referenced for specific descriptions of the features
or the devices and how it is implemented into the GUI.
The LEDMCUEVM-132 can be connected to several LED related EVMs to create your own system within
the confines of what the GUI supports for EVMs and devices. Here are a few example Device windows,
connections, and setups for using the LEDMCUEVM-132 with supported EVMs.
5.4.1 TPS92520EVM-133 Connections and Power UP
The TPS92520EVM-133 can be connected to the LEDMCUEVM-132 and use the associated GUI to monitor and
control the TPS92520-Q1 device using the SPI bus to read and write commands. Here is a typical setup for
controlling and testing the TPS92520EVM-133, note jumper locations are in red, see Figure 5-11.

5.4.5 TPS92682EVM-069 + TPS92520EVM-133 Connection and Power UP
The LEDMCUEVM-132 can be connected to the multiple EVMs to create more complicated LED systems. The
TPS92682EVM-069 and the TPS92520EVM-133 can be connect together such that the TPS92682EVM-069
boost a lower input voltage, such a battery, and boost it to a higher voltage for use by the buck LED driver
(TPS02520EVM-133). The LEDMCUEVM-132 and the GUI support these features by using the SPI bus. Here
is a typical setup for controlling and testing the TPS92682EVM-069 with the TPS92520EVM-133. The loads are
generally LEDs but can be a stacked diodes or power resistors depending on what testing is required. Use the
"TPS92520, TPS92682 - LPP074 - E1" selection from EVM Selection and Setup screen to control this setup.

When selecting the "TPS92520, TPS92682 - LPP074 - E1" from the EVM Selection and Setup window, simply
select the Add Device button to add the "682" at address 0 and change the selections to have the "520" at
address 1 then select Add Device to add the second device, see FIG. This will start up after it has reached the
number of devices you selected previously in the GUI, see Figure 5-18.

5.4.7 TPS92682EVM-069 + TPS92520EVM-133 + TPS92662EVM6-901 Connection and Power UP
Another example is using TPS92682EVM-069, TPS92520EVM-133, and the TPS92662EVM6-901. The
TPS92682EVM-069 and the TPS92520EVM-133 can be connected together such that the TPS92682EVM-069
boost a lower input voltage, such a battery, and boost it to a higher voltage for use by the buck LED driver
(TPS02520EVM-133). The TPS92662EVM6-901 is a lighting matrix manager that has the ability to individually
perform shunt FET dimming of the LEDs in the string. The LEDMCUEVM-132 and the GUI support these
features by using the SPI bus and the UART over CAN hardware of the LEDMCUEVM-132. Here is a typical
setup for controlling and testing the "TPS92520, TPS92682, TPS92662 - LPP074 - E2" selection from EVM
Selection and Setup screen.

When selecting the "TPS92520, TPS92682, TPS92662 - LPP074 - E2" from the EVM Selection and Setup
window, simply select two devices then select the Add Device button for both the 682 and 520 to start the GUI,
see Figure 5-21.

features sure as Phase Shift control, Width/DC control, selection boxes for "ALL" channels and "85" phase
shift. See the TPS92520EVM-074 Users Guide for specifics on the operation of the GUI and how it controls the
TPS92662-Q1 device.
