Introduction to mikromedia for PIC18FK
Mikromedia for PIC18FK is a compact smart
display and development platform with the
PIC18F67K40 microcontroller from Microchip.
The large 320x240 TFT color display will allow
you to build multimedia applications with speed
and ease. You can use it for development and
as a final product. A 320x240 TFT Color Display
with Touch Screen and Stereo MP3 Codec chip,
microSD™card, a preprogrammed PIC18FK MCU
and compiler support — you are set for creating
some amazing projects. It comes preprogrammed
with USB bootloader, but can also be programmed
with external programmers, such as mikroProg™
or ICD2/3. Mikromedia is compact and slim, and
perfectly fits in the palm of the hand, which makes

USB power supply - You can apply power
supply to the board using micro USB cable
provided with the board. On-board voltage
regulators provide the appropriate voltage
levels to each component on the board.
Power LED (green) will indicate the presence
of power supply.
You can also power the board using Li-Polymer battery,
via on-board battery connector. On-board battery
charger circuit MCP73832 enables you to charge the
battery over USB connection. LED diode (RED) will
indicate when battery is charging. Charging current is
~250mA and charging voltage is 4.2V DC.

You can program the microcontroller with a bootloader
which is preprogrammed by default. To transfer .hex
file from a PC to MCU you need bootloader software
(mikroBootloader USB HID) which can be downloaded
from:
3.1 Programming with mikroBootloader
Figure 3-2: mikroBootloader window
step 1 – Connecting clicker 2 for PIC18FK
01 To start, connect the USB cable, or if already connected press
the Reset button on your clicker 2 for PIC18FK. Click the Connect
button within 5s to enter the bootloader mode, otherwise existing
microcontroller program will execute.
After the mikroBootloader software is downloaded,
unzip it to desired location and start it.

The microcontroller can be programmed with mikroProg programmer and mikroProg Suite for PIC®software.
The mikroProg programmer is connected to the development system via the CN6 connector, Figure 3-9.
mikroProg is a fast
USB 2.0 programmer with
mikroICD™hardware In-Circuit
Debugger. Smart engineering allows
mikroProg™to support PIC10®, PIC12®, PIC16®,
PIC18®, dsPIC30/33®, PIC24®and PIC32®devices in
a single programmer. It supports over 570 microcontrollers
from Microchip®. Outstanding performance, easy operation and
elegant design are it’s key features.
Programing with mikroProg programmer
Figure 3-9:
Connecting mikroProg to mikromedia

mikroProg Suite for PIC software
mikroProg programmer requires
special programming software
called mikroProg Suite for PIC. This
software is used for programming
of ALL Microchip®microcontroller
families, including PIC10®, PIC12®,
PIC16®, PIC18®, dsPIC30/33®, PIC24®
and PIC32®. Software has intuitive
interface and SingleClick™programming
technology. Just by downloading the
latest version of mikroProg Suite 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.
Figure 3-10: Main window of mikroProg Suite for PIC®programming software

The microcontroller can be also programmed
with ICD2®or ICD3®programmer. These
programmers connects with mikromedia
board via ICD2 CONNECTOR BOARD.
In order to enable the ICD2® and ICD3®
programmers to be connected to the
development system, it is necessary to provide
the appropriate connector such as the ICD2
CONNECTOR BOARD. This connector should be
first soldered on the CN5 connector. Then you
should plug the ICD2® or ICD3® programmer
into it, Figure 3-11.

Board is equipped with reset button, which is located at the
top of the front side (Figure 4-2). If you want to reset the
circuit, press the reset button. It will generate low voltage
level on microcontroller reset pin (input). In addition, a reset
can be externally provided through pin 27 on side headers
(Figure 4-3).

Figure 4-1: Location of additional reset button
You can also solder additional reset button
on the appropriate place at the back side of
the board, Figure 4-1.

5. microSD Card Slot
Board contains microSD card slot for using microSD cards in your
projects. It enables you to store large amounts of data externally, thus saving
microcontroller memory. microSD cards use Serial Peripheral Interface (SPI) for
communication with the microcontroller.
Figure 6-1: microSD card slot

Board is equipped with 16MHz crystal oscillator (Y1) circuit
that provides external clock waveform to the microcontroller
CLKO and CLKI pins. This base frequency is suitable for further clock
multipliers and ideal for generation of necessary USB clock, which ensures
proper operation of bootloader and your custom USB-based applications.
The use of crystal in all other schematics is implied even if it is purposely left out, because of the schematics clarity.
