User LEDs

A bank of eight green, surface mount LEDs (SM1206 type) are provided for general

purpose use. The cathodes of these LEDs are each connected to an FPGA I/O pin

while the anodes are pulled to 2.5 V through a current limiting resistor. Driving the

corresponding FPGA I/O pin low illuminates the LED. Driving the pin high turns the

LED off. Table 2–13 lists the assignment for each user LED.

LCD

The develpment board includes a 16 character × 2 line LCD which connects directly to

the FPGA device. Table 2–14 lists the LCD pin assignments.
