The SmartGLCD 240x128 is a compact smart
display, with many on-board peripherals. It’s
designed to become a control interface of your
device. Main part of the board is a large 240x128
pixel graphical LCD with a 4-wire resistive touch
screen. It features RGB backlight, which can
greatly improve user experience, but can also
be used as a signaling feature. The heart of the
board is PIC18F87K22, an 8-bit microcontroller
delivering 12MIPS of processing power. Other
modules like USB UART, piezo buzzer, microSD
slot and connection pads can be found on board
as well. The board is preprogrammed with
UART bootloader. We have also provided a nice
example which will give you a great out-of-the-
box experience.

The SmartGLCD board can be powered in two dierent ways: via USB connector (CN1) using MINI-B USB cable provided with the board
(Figure 2-1), or via side headers (CN2 or CN4) using external 5V power supply (Figure 2-2 and Figure 2-3).
When the board is powered up the GLCD display will be automatically turned on. The USB connection can provide up to 500mA of current
which is more than enough for the operation of all on-board modules and the microcontroller as well.

5. Programming with bootloader
Microcontroller is preprogrammed with USB UART Bootloader,
which can be used to upload new device rmware. To trans-
fer rmware .HEX le from a PC to MCU you need to use mikro-
Bootloader USB UART application, which can be downloaded from:
Upon download, unzip it to desired location and start the
mikroBootloader application:

mikroBootloader software
01 When you start mikroBootloader software a window
should appear, as shown in the image above.
Before starting mikroBootloader software, connect SmartGLCD
to a PC using a USB cable provided with the package.

Press the Reset button on SmartGLCD board and click
Connect within 5s, otherwise the existing microcontroller
program will run. If connected, the button’s caption will be
changed to Disconnect.
Click the Browse for HEX button and from a
pop-up window (Figure 5-6) choose a .HEX le to be
uploaded in MCU memory.

Right click on the USB Serial Port (COM18) item and then select Properties.
Select Port Settings tab.
Click the Advanced... button.
Set Latency Timer to 1and click OK.
Tips and Tricks: Speed-up UART data transfer
If .HEX le transfer from your PC to
MCU is too slow, it’s possible to speed
up data transfer by setting latency
time of COM port to 1 ms. This is done
in Device Manager:

6. Programming with mikroProg™programmer
Figure 6-2:
The mikroProg can be also attached on the
front side of the board. In this case, solder
1x5 header to front side pads (CN3).
Figure 6-1:
The mikroProg can be attached on the back
side of the board. Just solder 1x5 header to
back side pads (CN3) before connecting it.
The microcontroller can be programmed with the external mikroProg™ programmer which can be connected to the board via CN3
connector. Before establishing this connection it is necessary to solder 1x5 male header to CN3 connection pads. This can be done in
both ways: on the bottom, or the top side, as shown in Figures 6-1 and 6-2.
If bootloader program is accidently erased you can upload it again through mikroProg programmer.
Program Bootloader18F87K22.hex can be found under Firmware folder (page 12).
note

Make sure to use only the front row of mikroProg’s IDC10 connector (side with a knob and
incision) when connecting it to 1x5 header on your SmartGLCD board.

7. mikroProg Suite™for PIC®Software
The mikroProg™programmer requires
special programming software called
mikroProg Suite™for PIC®. It can be
used for programming all Microchip®mi-
crocontroller families, including PIC10®,
PIC12®, PIC16®, PIC18®, dsPIC30/33®,
PIC24®and PIC32®. The software has
intuitive interface and SingleClick™
programming technology. Just down-
load the latest version of mikroProg
Suite™and your programmer is ready
to program new devices. mikroProg
Suite™is updated regularly, at least
four times a year, so your programmer
will be more and more powerful with
each new release.
