Landscape LCD EZ-Extender Interfaces
LCD Display
The Blackfin Landscape LCD EZ-Extender is shipped with a 3.5 in. landscape, 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 oscillator 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 control 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)
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 generated by activating the LCD display (X+, X-, Y+, Y-) connect to a single
connector (P1), controlled via the LCD display. You can access the controller 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 different 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™ programmable controller (Analog Devices AD7147) for applications
implementing push buttons and scroll wheels. The four push button sensors 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
1-4
Blackfin Landscape LCD EZ-Extender Manual
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 finger 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 interface. 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 STMicroelectronics Web site.
More information on the revision and configuration control is available in

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
Blackfin Landscape LCD EZ-Extender Manual

Jumper Settings
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 display (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).
JP5
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 prevents 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).

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 significant 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

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 Analog 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).

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).

Jumper Settings
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 particularly 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 populating 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 control 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
2-10
Blackfin Landscape LCD EZ-Extender Manual
Landscape LCD EZ-Extender Hardware Reference
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 control is that the flag pin remains free and can be used for other applications
(see Table 2-12).
