Roll over image to zoom in

The Graphical User Interface (GUI) comes in 3 versions, one each for FRDM-34931S-EVB, FRDM-34931-EVB and FRDM-33931-EVB. The GUI works with the board in conjunction with FRDM-KL25Z connected to the PC via a USB cable.

The GUI enables easy access to MCU I/Os controlling the PWM frequency, duty cycle, enabling/disabling while monitoring status flag pin for undervoltage, short circuit and over-temperature events as well as real time load current for implementing advanced diagnostics. Please refer to the user’s guide for accessing the procedure to install and use the GUI.
