I/O Devices
This section briefly describes the I/O devices included on the FT 6000 EVB, which consists of two
push buttons, two LEDs, a temperature sensor, a light sensor, an LCD, and a joystick.
Push Button Switches
The FT 6000 EVB includes two push-button switches. The switches are labeled
SW1
and
SW2
. The
SW1
push button is connected to the
IO9
pin on the FT 6000 Smart Transceiver. The
SW2
push
button is connected to a 74HC165 8-bit parallel-in/serial-out shift register, and data is shifted on the FT
6000 Smart Transceiver
IO4
(clock) and
IO5
(data) pins, with a latch strobe on
IO6
(active low to
capture). The button readings must be debounced under application control.
LEDs
The FT 6000 EVB includes two blue LEDs that are labeled
LED1
and
LED2
.
LED1
is connected to
the FT 6000 Smart Transceiver
IO2
pin when jumper pins 9-10 on JP31 are connected.
LED2
is
connected to the
IO3
pin when jumper pins 11-12 on JP31 are connected.
Temperature Sensor
The FT 6000 EVB includes a temperature sensor based on a 1-Wire
®
Maxim Integrated Products
digital thermometer (Part No. DS18S20). The thermometer uses the Touch I/O interface and is
connected to the FT 6000 Smart Transceiver
IO7
pin. For more information about this temperature
sensor, see its data book at
datasheets.maxim-ic.com/en/ds/DS18S20.pdf
.
Light-Level Sensor
The FT 6000 EVB includes a light-level sensor based on a Texas Advanced Optoelectronic Solutions
®
Light-To-Digital Converter (Part No. TSL2561). The light sensor is connected to the FT 6000 Smart
Transceiver
IO0
and
IO1
pins (via the I
2
C interface). The I
2
C address for the light level sensor is
0x39. For more information about this light sensor, see its data book at
