Landscape LCD EZ-Extender Setup
It is very important to set up all components of the system containing the
Blackfin Landscape LCD EZ-Extender, then apply power to the system.
The following procedure is recommended for the correct setup.
1. Read the applicable design interface section in this chapter—the
text provides an overview of the interface capabilities.
2. Read “System Architecture” on page 2-2 to understand the physical
connections of the extender board. For detailed information, refer
to “Landscape LCD EZ-Extender Schematic” on page B-1.
3. Set the jumpers on the extender board. Use the block diagram in
Figure 2-1 on page 2-2 in conjunction with “Jumper Settings” on
page 2-3.
4. Set the switches and jumpers on the EZ-KIT Lite/EZ-Board. If not
already, familiarize yourself with the board documentation and
schematic drawings (see “Product Information”).
Compare the parallel peripheral interface (PPI) or expansion inter-
face II connector signals of the extender board with the EZ-KIT
Lite/EZ-Board signals to ensure there is no contention. For exam-
ple, it may be necessary to disable other devices connected to the
PPI or expansion II connector of the processor or disable the push
buttons on the EZ-KIT Lite/EZ-Board.
5. Install the extender on the EZ-KIT Lite/EZ-Board via the PPI or
expansion II connector.
6. Configure any other interfacing boards; for example, another
EZ-Extender board.
7. Power your system.
Blackfin Landscape LCD EZ-Extender Manual 1-3
Landscape LCD EZ-Extender Interfaces
LCD Display
The Blackfin Landscape LCD EZ-Extender is shipped with a 3.5 in. land-
scape, QVGA (320 x RGB x 240) display with an LCD backlight. All
LCD data, touchscreen pins, and power pins connect to the display via a
single connector (P1). The 18-bit display operates in 16-bit mode
(RGB 5-6-5) and connects to the PPI [15–0] data pins of the processor.
The display also uses the serial peripheral interconnect (SPI) port of the
processor for control register setup. The LCD display can operate at a
VDDIO of 1.6V to 3.6V. This allows you to connect the LCD display to
the PPI/SPI interface of the processor gluelessly, without the need for
voltage translation circuitry— a great benefit for power-sensitive
applications.
The PPI clock of a Blackfin processor and the clock required by the LCD
display are driven by the on-board 5 MHz oscillator. By default, the oscil-
lator is enabled and drives the PPI interface. You can use the clock
generated by the processor or can disable the 5 MHz oscillator by setting
the appropriate jumpers on the extender. See “Jumper Settings” on
page 2-3 for more information.
At power-up, the LCD backlight circuit is disabled. By default, the shut
pin of the LCD display turns the display OFF. Write to the respective con-
trol registers to enable the backlight and take the display out of the shut
mode. These settings provide significant power savings and are suited for
power-sensitive applications.
For more information about the LCD display, go to the Sharp Web site.
An example program demonstrating capabilities of the LCD display is
available in the Examples folder of the installation directory.
LCD Touch Controller (AD7879)
1-4 Blackfin Landscape LCD EZ-Extender Manual
LCD Touch Controller (AD7879)
The Blackfin Landscape LCD EZ-Extender is shipped with a low-cost
resistive touch controller (Analog Devices AD7879). The four pins gener-
ated by activating the LCD display (X+, X-, Y+, Y-) connect to a single
connector (P1), controlled via the LCD display. You can access the con-
troller via the SPI interface of the Blackfin processor. The controller
generates an interrupt request for the processor whenever any new data is
available or when a user touches the LCD Display. The processor uses the
SPI interface to read the appropriate registers of the AD7879 controller.
The IRQ line connects the AD7879 controller to the processor via the
processor’s general-purpose I/O (GPIO) pin. By default, the AD7879
controller uses the SPI select 1 and GPIO1 pins. “Jumper Settings” on
page 2-3 describe how the GPIO and SPI selects can be varied for differ-
ent EZ-KIT Lites and EZ-Boards.
For more information about the AD7879 touch controller, go to
www.analog.com and search for AD7879.
An example program demonstrating capabilities of the touch controller is
available in the Examples folder of the installation directory.
Capacitive Touch Controller (AD7147)
The Landscape LCD EZ-Extender is equipped with a CapTouch™ pro-
grammable controller (Analog Devices AD7147) for applications
implementing push buttons and scroll wheels. The four push button sen-
sors and one scroll wheel are located on the top side of the extender’s
printed circuit board (PCB).
When the respective sensor is activated, the captouch controller recognizes
and communicates the change to the Blackfin processor via the processor’s
2-wire interface (TWI). The AD7147 controller generates an interrupt
request for the Blackfin processor whenever any new data is available or
Blackfin Landscape LCD EZ-Extender Manual 1-5
Landscape LCD EZ-Extender Interfaces
when a user touches the push buttons (PB1—4) or scroll wheel. The push
buttons and scroll wheel are copper pads created inside the PCB. Touch
the respective push button or traverse around the scroll wheel with a fin-
ger to enable the sensor pads and to generate the interrupt request. The
IRQ line connects the AD7147 controller to the processor via its GPIO
pin. By default, the AD7147 controller uses the SPI select 2 and GPIO2
pins. “Jumper Settings” on page 2-3 describe how the GPIO and SPI
selects can be varied for different EZ-KIT Lites and EZ-Boards.
For more information about the AD7147 touch controller, go to
www.analog.com and search for AD7147.
An example program demonstrating capabilities of the touch controller is
available in the Examples folder of the installation directory.
Serial ROM
The Blackfin Landscape LCD EZ-Extender is equipped with a 2 KB serial
ROM device (M24C02) for revision and configuration control: bill of
materials and PCB revision information is available by reading the ROM.
The part connects to the Blackfin processor via the processor’s TWI inter-
face. By default, the serial ROM is read-only to protect the internally
stored contents. On the extender, the last three significant TWI address
bits are strapped to logic ‘0’ (default). To modify the last three significant
TWI address bits, use the provided jumpers; see “Jumper Settings” on
page 2-3 for more information.
For more information on the M24C02 device, go to the STMicroelectron-
ics Web site.
More information on the revision and configuration control is available in

2-4 Blackfin Landscape LCD EZ-Extender Manual
AD7147 ADDR0 Jumper (JP1)
The AD7147 ADDR0 jumper (JP1) changes the least significant address bit
used to communicate to the AD7147 touch controller via the TWI inter-
face of the processor. By default, JP1 requires no jumpers. When no
jumper is installed, the ADDR0 bit is pulled low and is a logic ‘0’
(see Table 2-1).
LCD SPI Chip Select Jumper (JP2)
The LCD SPICS jumper (JP2) connects the chip select pin of the serial
peripheral interconnect (SPI) interface of the LCD display to one of three
SPI select pins of the Blackfin processor. JP2 allows you to choose any one
of the available SPI select pins (SPISEL1—3) of the processor
(see Table 2-2).
By default, JP2 is populated, so that the SPISEL1 pin of the expansion
interface II or the parallel peripheral interface (PPI) stamp connector can
be used. When the PPI stamp connector is used to attach the extender,
SPISEL3 is unavailable and only SPISEL1 and SPISEL2 are available for JP2.

LCD Touch SPI Chip Select Jumper (JP3)
The LCD touch SPICS jumper (JP3) connects the chip select pin of the
AD7879 SPI interface (U1) to one of three SPI select pins of the Blackfin
processor. JP3 adds flexibility to the extender: you can choose any one of
the available SPI select pins (SPISEL1—3) of the processor (see Table 2-3).
By default, JP3 is populated, so that SPISEL2 of the expansion interface II
or the PPI stamp connector can be used. When the PPI stamp connector is
used to attach the extender, SPISEL3 is unavailable and only SPISEL1 and
SPISEL2 are available for JP3.
LCD Reset Jumper (JP5)
The LCD reset jumper (JP5) connects the reset pin of the LCD display to
one of the following.
• The reset pin of the EZ-KIT Lite/EZ-Board
• A general-purpose I/O (GPIO) pin of the AD7147 capacitive
touch controller (U3)
• A GPIO pin connected directly to the Blackfin processor

Jumper Settings
2-6 Blackfin Landscape LCD EZ-Extender Manual
JP5 adds flexibility to the extender: you can control the LCD display reset
by one of three available methods. By default, JP5 is populated so that the
EZ-KIT Lite/EZ-Board reset pin connects to the reset pin of the LCD dis-
play (P1.28). Consequently, a reset supervisory circuit located on the
EZ-KIT Lite/EZ-Board controls the reset pin going to the LCD display
(see Table 2-4).
To control the LCD display reset via software, write to the respective
AD7147 (U3) control registers using the 2-wire interface (TWI) of the
processor and control the AD7147 GPIO pin.
When using the expansion interface II (EZ-Boards), you can also control
the LCD display reset via the GPIO4 flag pin. GPIO4 connects directly to
the processor and LCD display, and can be controlled without the need to
communicate to the AD7147 controller. The GPIO4 pin is unavailable on
the PPI stamp connector; as a result, when using a PPI connector, you can
not use GPIO4 to control the LCD display reset.
PPICLK Disable Jumper (JP6)
The PPICLK disable jumper (JP6) disables and tri-states the buffer (U4) that
drives the 5 MHz clock coming from the on-board oscillator (U2). The
buffer is powered via the V_Select pin and used for level translation of the
3.3V oscillator to the VDDIO coming from the EZ-KIT Lite/EZ-Board.
Use JP6 to disable the buffer if the PPI clock is generated via the Blackfin
processor. This tri-states the 5 MHz clock driven by the buffer and pre-
vents any signal contention issues. By default, JP6 is not populated, and
the 5 MHz clock is driven to the PPI clock line (see Table 2-5).

AD7147 ADDR1 Jumper (JP7)
The AD7147 ADDR1 jumper (JP7) changes the second least significant
address bit used to interface to the AD7147 capacitive touch controller via
the TWI interface of the Blackfin processor. By default, JP7 requires no
jumpers. When no jumper is installed, the ADDR1 bit is pulled low and is a
logic ‘0’ (see Table 2-6).
Serial ROM Addr Jumper (JP8)
The serial ROM address jumper (JP8) can change the three least signifi-
cant address bits (ADDR0—3) used to interface to the serial ROM device via
the TWI interface of the Blackfin processor. By default, JP8 requires no
jumpers. When no jumpers are installed, all three address bits are pulled
low and are logic ‘0’. This causes the serial ROM device select (address) to
default to a binary 1010 000. To change any one of the three least signifi-
cant address bits to a logic ‘1’, install the respective jumper (Table 2-7).

Serial ROM Write Protect Jumper (JP9)
The serial ROM write protect jumper (JP9) protects the entire contents of
the memory device (M24C02) from inadvertent write operations. By
default, JP9 has a jumper installed, making the memory a read-only
device. The default setting ensures that any hardware or software revision
information stored in the ROM is preserved. Remove JP9 when you need
to write to serial ROM (see Table 2-8).

AD7879 PENIRQ Jumper (JP10)
The AD7879 PENIRQ jumper (JP10) connects the interrupt pin of the Ana-
log Devices AD7879 LCD touch controller (U1) to one of three GPIO
pins of the Blackfin processor. JP10 adds flexibility to the extender: you
can choose any one of the available GPIO pins (GPIO1—3). By default, JP10
is populated so that the GPIO1 pin of the expansion interface II or the PPI
stamp connector can be used to connect to the AD7879 Penirq pin (see
Table 2-9).
AD7147 INT Jumper (JP11)
The AD7147 INT jumper (JP11) connects the interrupt pin of the Analog
Devices AD7147 capacitive touch controller (U3) to one of three GPIO
pins of the Blackfin processor. JP11 adds flexibility to the extender: you
can choose any one of the available GPIO pins (GPIO1—3). By default, JP11
is populated so that the GPIO2 pin of the expansion interface II or the PPI
stamp connector can be used to connect to the AD7147 interrupt pin (see
Table 2-10).

Oscillator Disable Jumper (JP12)
The oscillator disable jumper (JP12) disables the 5 MHz oscillator driving
the PPI0CLK net and LCD display. The disabled oscillator mode is particu-
larly suited for low-power applications.
By default, JP12 requires no jumpers. As a result, the oscillator is driving
the 5 MHz clock. You can permanently disable the oscillator by populat-
ing a jumper between JP12.2 and JP12.3. The oscillator also can be
enabled or disabled via the GPIO pin of the AD7147 capacitive touch
controller. To enable or disable the oscillator, write to the respective con-
trol registers of the AD7147 controller (U3) and place a jumper between
JP12.1 and JP12.2 (see Table 2-11).
LCD Backlight Enable Jumper (JP13)
The LCD backlight enable jumper controls the power circuitry for the
LCD backlight. The disabled LCD backlight option is particularly suited
for low-power applications.
By default, JP13 requires a jumper between JP13.1 and JP13.2. When the
EZ-Extender is powered up, the backlight power circuit (VR1) is OFF.
To enable the LCD backlight, use the GPIO (Aux) pin of the AD7879
touch controller (U1). Write to the appropriate control registers of the
controller using the SPI interface of the Blackfin processor. You also can
control the LCD backlight via the GPIO3 flag pin, which is linked to the
Blackfin processor directly. In the latter case, you do not need to

communicate to the controller in order to control the LCD backlight. The
benefit of using the AD7879 device over the GPIO3 flag pin for LCD con-
trol is that the flag pin remains free and can be used for other applications
(see Table 2-12).

Expansion II PPI Connector (J1)
The expansion II PPI connector (J1) connects the Landscape LCD
EZ-Extender to the PPI interface of the Blackfin processor. Use J1 to con-
nect the extender to the ADSP-BF526 EZ-Board/ EZ-KIT Lite. The reset,
power, and ground lines from the ADSP-BF526 EZ-Board/ EZ-KIT Lite
also are brought up from J1 to the extender.
Use the expansion II PPI connector and low speed I/O (LSIO) connector
(J2, described in “Expansion II LSIO Connector (J2)”) on the
ADSP-BF526 EZ-Board/ EZ-KIT Lite for the extender to function
properly.
Expansion II LSIO Connector (J2)
The expansion II LSIO connector (J2) connects the Landscape LCD
EZ-Extender to the SPI, TWI, and GPIO pins of the Blackfin processor.
Use J2 to connect the extender to the ADSP-BF526 EZ-Board/ EZ-KIT
Lite. The power and ground lines from the ADSP-BF526 EZ-Board/
EZ-KIT Lite also are brought up from J2 to the extender.
Use the expansion II PPI connector and LSIO connector on the
ADSP-BF526 EZ-Board/ EZ-KIT Lite for the extender to function
properly.
PPI Stamp Connector (J3)
The PPI stamp connector (J3) connects the Landscape LCD EZ-Extender
to the PPI, SPI, TWI, and GPIO pins of the Blackfin processor. J3 also
connects the extender with the reset, power, and ground lines of the
ADSP-BF537, ADSP-BF538, and ADSP-BF548 processors. Use J3 to
connect the extender to the ADSP-BF537, ADSP-BF538, and
ADSP-BF548 EZ-KIT Lites. When using J3, do not use J1 and J2.
