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

Setting up communication via a USB interface for the controller board is similar to the set up for SPI communication via the Cheetah host adapter.
  1. Start the DLPC230-Q1 Control Program Lite.
  2. With the DLPC231 controller board off, short pins 2-3 together on jumpers J16, J17, J18, and J19 of the controller board using a jumper
  3. On the connection page, set the DLPC230-Q1 Host to SPI and select the Cypress option from the drop down menu.
  4. The "Connection" Settings can be left the same way they were previously for SPI communication.
  5. Click the Connect button. The green circle next to the Connect button then lights up to indicate that connection was successful to USB.
