ADP5588 Keypad I/O Expander
Evaluation Board
EVAL-ADP5588
The demonstration board assembly is powered either via J10 or
the USB port and comes with a free graphical user interface (GUI)
to exercise the ADP5588 features. In addition to the keypad
switches, the motherboard also has 18 GPO LED indicators (D1
through D11, D22 through D27, and D30), power status LEDs
(D19 and D21), a 2.7 V regulator, a 3.3 V regulator, and jumpers
(J1 through J8 and J13 through J22) to configure the GPIOs as
GPIs, GPOs, or keypad lines. The motherboard is equipped with
jumpers (LK8 and LK10) to configure the board to use either
external regulated voltages via J10 or the on-board regulators when
plugged into the USB port. When using the USB port as the power
source, place jumpers across Pin 1 and Pin 2 of LK8 and LK10.
When using external voltages, place jumpers across Pin 2 and
Pin 3 of LK8 and LK10. VCC (Pin 3 of J10) should be 1.8 V to 3.0 V,
and VBOARD (Pin 1 of J10) should be 3.3 V.

GENERAL DESCRIPTION
A set of switches (SW1 through SW18) provides logic high
(Logic 1) or logic low (Logic 0) drives to the GPIOs configured
as GPIs. Column 8 and Column 9 of the IC have an additional
jumper (J9) that allows the user to configure theses lines into
light sensor comparator inputs. Place a jumper across Pin 1 and
Pin 3 of J9 and another across Pin 2 and Pin 4 of J9 to configure
these pins as Keypad Column 8 and Keypad Column 9, or place
a jumper across Pin 3 and Pin 5 of J9 and another across Pin 4
and Pin 6 of J9 to configure these pins as light sensor inputs.
The ADP5588 demonstration board is used to exercise the
features of the ADP5588 keypad/GPIO expander IC. It consists
of a daughterboard and a motherboard. The motherboard houses
the keypad (80 switches), a USB connector (JP1), a reset switch
(S17), and all the hardware necessary to power the IC and establish
USB communication with the PC. Two 20-pin connectors (J11
and J12) are used to plug in the daughterboard. The ADP5588
IC is mounted on the daughterboard along with the LK1 and LK2
jumpers, which are used to insert or remove the C19 and C20
capacitors from the light sensor comparator circuitry.

light up. Then click START>All Programs>Analog Devices>
ADP5588Evaluation Software.
The software then detects the presence of the board USB
interface and prints the message Firmware Downloaded okay
at the bottom left side of the screen (see Figure 23). If USB
communication is not established, a Firmware not Downloaded
USB Communication Error prints instead. If the latter message
appears, unplug the board and try it again.
THE APPLICATION TABS
The ADP5588 software application has four tabs: the Keypad
application tab, the GPIOs configuration tab, the Light-Sensors
configuration tab, and the History tab. The History tab allows
you to record a sequence of commands that can be converted into
scripts later on. This is useful during software development.

Keypad Configuration
To program a GPIO pin as a keypad in the GPIO tab:
The ADP5588 has eighteen GPIOs that can be programmed as
keypad lines to make up a 10 × 8 keypad matrix (80 keys). If a
smaller size matrix is needed, the unused GPIOs can be used for
other functions (other functions include GPIs, GPOs, and light
sensor comparator inputs).
1.
Motherboard Jumper J1 through Motherboard Jumper J8 and
Motherboard Jumper J13 through Motherboard Jumper J22
must be set in the KP position in any row or column that will be
used as part of the keypad matrix.
2.
For more information, see Figure 32.
Set the bits for the columns and rows that need to be
configured as keypads in Register 0x1D, Register 0x1E,
and Register 0x1F and click Program 0xXX for each
register that needs to be programmed (XX represent the
register address to be programmed).
Enable KE interrupt for key presses and releases, if needed,
by setting Bit 0 in Register 0x01. Register 0x04 through
Register 0x0D make up the FIFO registers for the key event
table. For more details on the keypad operations, see the
ADP5588 data sheet.

The ADP5588 allows the user to configure any of the eighteen
GPIOs as GPIs or GPOs (see Figure 24).
Motherboard Jumpers J1 through Motherboard Jumpers J8 and
Motherboard Jumpers J13 through Motherboard Jumpers J22
must be set in the GPI or GPO position for any row or column
that is to be used as GPI or GPO.
5.
6.
GPI Configuration
To configure a row or column to GPI, do the following:
1. Clear the bit for the row or column to be configured as GPI
in Register 0x1D, Register 0x1E, and Register 0x1F.
2. Clear the bit for the row or column to be configured as GPI
in Register 0x23, Register 0x24, and Register 0x25.
3. If interrupt triggering is needed, set the GPIO interrupt
enable bit for the rows and columns in Register 0x1A,
Register 0x1B, and Register 0x1C.
Define the trigger level for any of the rows or columns for
which interrupt is enabled (Register 0x26 through
Register 0x28).
Enable GPIO DEBOUNCE, if needed, for the rows or
columns that are configured as GPIs (Register 0x29
through Register 0x2B).
Configure GPIO PULLUP, if needed, for the rows or
columns that are configured as GPIs (Register 0x2C
through Register 0x2E).
Read Register 0x14, Register 0x15, and Register 0x16 to see
the GPIO DATA STATUS; read Register 0x11, Register 0x12,
and Register 0x13 for the GPIO INTERRUPT STATUS. Green
LEDs at the right side of the GPIOs configuration tab light up to
indicate the status of the pins or interrupts.
GPIs can be programmed as part of the event FIFO/key event
table, see the ADP5588 data sheet for more details.
Rev. 0 | Page 9 of 20
EVAL-ADP5588
GPO Configuration
To GPO configure a row or column, do the following:
1. Clear the bit for the row or column that needs to be
configured as a GPO in Register 0x1D, Register 0x1E,
and Register 0x1F.
2. Set the bit for the row or column that needs to be
configured as a GPO in Register 0x23, Register 0x24,
and Register 0x25.
3. Set the drive level for the GPO lines in Register 0x17,
Register 0x18, and Register 0x19.
Columns or rows configured as GPO are not read into
Register 0x014, Register 0x15, and Register 0x16. The D1
through D11, D22 through D27, and D30 status LED indicate
the level of the GPIOs configured as GPOs.

Figure 25. Light Sensors Configuration
Light Sensor Comparator Trip Reference Programming
3.
The ADP5588 is equipped to support two light sensor comparator
inputs. Both light sensors (D12 and D13) are mounted on the
motherboard (see the layout for the light sensor location in
Figure 32).
Use the Light-Sensors tab to program the light sensors and
comparator parameters. Column 8 and Column 9 are used as
the light sensor comparator inputs. When Column 8 and
Column 9 are programmed as light sensor comparator inputs,
LK1 and LK2 should be placed on the daughterboard. LK1
and LK2 connect C19 and C20 to the comparator inputs; these
capacitors are needed for the light sensor comparator operation
and should be placed only if Column 8 and/or Column 9 is
configured as a light sensor input.
To program Column 8 and Column 9 as light sensor inputs
1. Clear Bit 0 and Bit 1 in Register 0x1F.
2. Set Bit 0 and/or Bit 1 in Register 0x30 to enable
Comparator 1 and/or Comparator 2.
4.
Set Bit 2 and/or Bit 3 of Register 0x30 to enable interrupt
for the comparators, if needed.
Set Bit 0 and Bit 1 of Register 0x31 and Register 0x32 to
enable the comparator trip points.
Use Register 0x33 through Register 0x3A to set individual
comparator trip references and hysteresis.
Trip point values are expressed in μA or lux. Ensure that the
right values are picked for the correct lighting environment; the
comparator does not trip if the values are not within the brightness
range of the lighting environment.
Use the filter time to increase the number of photo sensor readings
necessary to trip from one lighting environment to another.
The filter time register is programmable from 80 ms minimum
to 10.24 sec (see the ADP5588 data sheet for more details on
sensor operation).
Comparator L3 OUT and Comparator L2 OUT are used in
conjunction with the force read bits in Register 0x31 and
Register 0x32 to determine the photo sensor readings during
a force read.

Figure 26. History Tab
History
The History tab is used to record command sequences that can
be used later as script files.
To start recording commands, click Enable Command History log.
The script file allows the user to program all the register settings
without having to repeat these commands one by one. This
feature can be used to automate certain functions that will be
used later or repeatedly (useful for software development).
When command sequences are recorded, the list of commands
can be saved as a script file and later used as input to program
all of the registers for a particular configuration or setting.

The keypad on the demonstration board is labeled from A0 through J7, but the application software keys go from 1 to 80. The letters in
the key nomenclature denote the columns, and the numbers denote the rows. Therefore, A0 is equivalent to Key 1, and J7 is equivalent to
Key 80. Use Table 1 to find the equivalent number key in the software.
