KT33814UG User’s Guide Rev. 2.0 4/2013 Freescale Semiconductor 3 Introduction 4 Introduction The KIT33814AEEVBE Evaluation Board is an easy-to-use circuit board that allows the user to exercise all the functions of the MC33814 two cylinder small engine control IC. A PC communicates to the EVB through a USB/SPI Dongle (KITUSBSPIDGLEVME) connected to the PC’s USB port. The Freescale SPIGen (version 7.0) program provides the user interface to the MC33814 SPI port and allows the user to send commands to the IC and receive status from the IC. 5 Evaluation Board Features This evaluation board consists of a MC33814 two cylinder small engine control IC, a USB to SPI Dongle interface, and power conditioning circuitry. All +5.0 V VCC power required by the board is obtained from the MC33814 built-in power regulator. A +12 V VBAT supply provides the power to the three internal voltage regulators. 6 MC33814 Device Features The MC33814 is an engine control analog power IC intended for two cylinder motorcycle and other small engine control applications.

To install the software, go to www.freescale.com/analogtools and select your kit. Click on that link to open the corresponding Tool Summary Page. Look for “Jump Start Your Design”. Download to your computer desktop the SPIGen software as well as the associated configuration file. Run the install program from the desktop. The Installation Wizard will guide you through the rest of the process. To use SPIGen, go to the Windows Start menu, then Programs, then SPIGen, and click on the SPIGen icon. The SPIGen Graphic User Interface (GUI) will appear. Go to the file menu in the upper left hand corner of the GUI, and select “Open”. In the file selection window that appears, set the “Files of type: ” drop-down menu to “SPIGen Files (*.spi)”. (As an exceptional case, the file name may have a .txt extension, in which case you should set the menu to “All Files (*.*)”.) Next, browse for the configuration file you saved on your desktop earlier and select it. Click “Open”, and SPIGen will create a specially configured SPI command generator for your evaluation board. The GUI is shown in Figure 3. The text at the top is the name of the configuration file loaded. The left side panel displays folders that group user interfaces. The interfaces in the pre-installed MC33814 folder pertain specifically to the board under discussion.The process of loading the configuration file has assigned a list of “Extra Pins” as well as a list “Quick Commands”, all of which are board-specific.

It is a working hardware/software example that allows a user to become familiar with the MC68HC908JW32 microcontroller by means of an actual useful application, a USB to SPI and USB to parallel converter. The main function provided by this kit is to allow a PC, that may not have a parallel port, to communicate with other Freescale Evaluation Kits, via a USB port. The USB port is a standard feature on almost every new PC. This kit makes use of the MC68HC908JW32’s built-in USB, SPI and parallel ports. Figure 6.
