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.
