2.2.2 Connecting the FTDI Digital Controller

To connect the FTDI digital controller on the EVM board to the PC, align and firmly connect the USB connector to the J3 connector. Verify the connection is snug; a loose connection can cause intermittent operation. A 100 mil header (J22) is available for external communication. Table 3-6 lists the J22 pin definitions. To use external communication, disconnect jumpers J17 and J18 to remove the connection to the FTDI controller. Resistors R7 and R9 can be populated for pullups for I2C. These resistors do not need to be populated for the FTDI driver.
