EVB Setup and Using the Hardware
10 EVB Setup and Using the Hardware
To perform the examples included in the CD the following connections and setup must be performed:
1.Make sure the SPIGen 5.0X program is installed on the PC and it can communicate with the USB/SPI Dongle as
described in that kit’s documentation.
2.Connect the USB/SPI Dongle to the MC33926 EVB via a 16 pin ribbon cable. Make sure to orient the cable so that
pin1 on both the USB/SPI Dongle and the MC33926 EVB are connected correctly, pin 1 to pin 1.
3.Connect the USB/SPI Dongle to a PC, LED 2 on the USB/SPI Dongle and the VDD LED on the MC33926 board
should both be illuminated.
4.Attach a +12 VDC supply (do not turn on power yet) to the power connector on the MC33926 EVB, making sure to
observe the GND and +12 V terminals. The current capability of the +12 V supply should exceed the maximum
total current that the number of simultaneously ON loads will require.
5.Attach loads to the MC33810 OUT0 - OUT3 terminals between the VPWR terminals and the OUTx terminals. One
possible demo load is a 10 W halogen G4 Base T3 bulb (used in landscape lighting applications). This load will
draw approximately 850 mA and fits nicely into the screw terminals.
6.Attach 10 W halogen G4 Base T3 bulbs to the H-Bridge OUT1 and OUT-2 terminals from OUT1 to GND and
another load from OUT2 to GND.
7.Launch SPIGen and from the “
File
” menu, select “
Open
” and browse to the CD containing the
“MC33926_EVB_CONFIGURATION_FILE.spi” file. The title on the SPIGen screen should change from
“Generic SPI Generator” to “MC33926 SPI Generator”.
8.Turn on the +12 Volt Supply. The bulbs connected to the H-Bridge OUT1 and OUT2 should illuminate immediately.
Verify that all is working correctly by clicking on the “Extra Pins” button in the SPIGen main screen and then click
on the DATA 0 “High” button. The OUT1 bulb should extinguish. Clicking on the DATA 1 “High” button should
extinguish the OUT2 bulb.
9.Click on the Control 0 “High” button. The bulb connected to OUT0 on the MC33926 EVB and LED1 on the
USB/SPI Dongle should be illuminated. Click on the Control 0 “Low” button and the bulb connected to OUT0 and
LED1 on the USB/SPI Dongle.
