Potentiometer and Dip Switches
There are 8-bit dip switches (S3). They are general purpose and are user programmable. A general
purpose potentiometer (R46) is next to the dip switches. This potentiometer can be routed to the
chip using the GPIO pins. The second potentiometer (R46) is specifically meant to control the con-
trast for the LCD daughter card in the LCD1 slot.

Header connected to the switch S4. S4 is a general purpose switch.
Header connected to the potentiometer
V - Vdd pin: This pin provideS a maximum of 50mA at 5V to an external
board. This pin is only to source the current. DO NOT SUPPLY POWER TO
THIS PIN FOR POWERING CY8CLED16P01 DEVICE. Please note that PWR
jumper needs to be connected for enabling this functionality
G - Gnd Pin: This pin can provide the ground reference to an external board.
This pin connects to the ground pin of the external board.
D - I2C Data (SDA): This is the data line for the I2C communication. This pin
is directly connected to the CY8CLED16P01 device
C - I2C Clock (SCL): This is the clock line for the I2C communication. This
pin is directly connected to the CY8CLED16P01 device.
R – Reset: Connecting the reset of an external board to this pin will enable
the resetting of the CY8CLED16P01 chip via external board. This way, on
resetting the external board, the CY8CLED16P01 device on CY3276 board
will also get resetted. Please note that RES jumper needs to be connected
for enabling this functionality.
These dip switches are general purpose and can be routed to any port of
the CY8CLED16P01 chip.
This is a variable resistor that connects to the VR header. It can be used to
generate a voltage between +5V and GND.
Adjusting this potentiometer adjusts the contrast on the LCD Daughter
Card.
