16 FT 5000 EVB Hardware Details
The following table lists the I/O pins and I/O devices associated with the jumpers on JP31.
Jumper I/O Pin I/O Device/Functionality on FT 5000 EVB
1-2 IO0 SCL LCD
3-4 IO0 SCL L Light sensor
5-6 IO1 SDA LCD
7-8 IO1 SDA L Light sensor
9-10 IO2 LED1
11-12 IO3 LED2
13-14 IO4 SWCLK (Shift register clock for SW2 and Joystick)
15-16 IO5 SWIN (Shift register data in for SW2 and Joystick)
Switch, Joystick, Temperature Sensor, and USB Connections (JP32)
This set of jumpers is used to connect the shift register for the SW2 push button (line 3 of three) and
joystick (SW3), temperature sensor, USB interface, SW1 push button, and I/O pull-downs on the FT
5000 EVB. The 1-2 pins on JP32 are used with the 13-14 and 15-16 pins on JP31 for bitshift I/O with
the SW2 push button and the Joystick. By default, the switch and temperature sensor jumpers are
connected, and the USB interface jumpers are disconnected as illustrated in the figure below. You can
use an I/O line for other I/O functions by disconnecting the jumper that connects the I/O line to an I/O
device on the FT 5000 EVB.
