3.4 Connecting EVM to the DLPC230-Q1 Control Program via SPI

  1. Start the DLPC230-Q1 Control Program Lite.
  2. With the controller board powered off, short or populate pins 1 and 2 of J10, J11, J12, and J13 together with a jumper and then plug the SPI adapter into J2 of the controller board.
  3. -On the Connection page, set the DLPC230-Q1 Host to SPI and select the Cheetah from the drop down menu (see Figure 4-3). Note, the Cheetah must be connected to computer with USB cable for the Cheetah to show up in the drop-down menu.
