The SmartGLCD 240x128 is a
full-featured development tool
for experimenting
with Graphical
LCD display.
Main advantage
of SmartGLCD is
resistive Touch Panel
which in combination with
Graphical LCD display makes
perfect tool for developing
devices which can be used
as control for home automation,
industrial equipment etc.
Microcontroller PIC18F8722 is a heart
of the SmartGLCD. It comes with preinstaled
bootloader program so you don’t need external
programer for MCU programming. To utilize MCU pins
SmartGLCD is equipped with marked pads.

3. Programming with bootloader
For programming, microcontroller use bootloader program which
is preinstaled in to MCU memory. To transfer .hex le from a PC
to MCU you need bootloader software (mikroBootloader) which
can be downloaded from:
After software is downloaded unzip it to desired location and
start mikroBootloader software.

Tips and Tricks: Speed-up UART data transfer
If .hex le transfer from your PC to MCU
is to slow you can try to speed-up data
transfer by seting latency time of COM
port to 1. To change latency time go to
Device manager:

The microcontroller can be programmed with external programmer mikroProg.
The external programmer is connected to the development system via marked
pads CN3, Figure 4-1.
In order to connect the external programmer to the development system, it is
necessary to provide a 1x5 header that should be soldered to pads CN3.
If bootloader program is accidently erased you can upload it again via mikroProg
programmer. Program Bootloader18F8722.hex can be found under Firmware
folder (page 10).

external programmer

mikroProg programmer can be also attached on the front side of
the SmartGLCD. Just solder 1x5 header to pads CN3. This is ideal
placment if you prefer using mikroProg
instead of bootloader.

The development system features
a Graphical LCD 240x128 display
covered with a resistive touch panel.
Together they form a functional unit
called a touch screen. It enables data
to be entered and displayed at the same
time. The way of entering and displaying
data depends on the program loaded into
the microcontroller.
Resistive touch panel is suitable for
usage with a plastic pen which have
rounded tip. Finger press is always available
but bare in mind that you use touch
panel and there’s no need for too
much pressing force.

There is a
built-in microSD
card slot for microSD
cards provided on the
development system. It
enables the system to additionally
expand available memory space. The
Serial Peripheral Interface (SPI) is used for
communication between the microcontroller and
microSD card.
