Introduction to mikromedia for PIC24EP

The mikromedia for PIC24EP® is a compact
development system with lots of on-board
peripherals which allow development of devices
with multimedia contents. The central part of
the system is a 16-bit PIC24EP512GU810
microcontroller. The mikromedia for PIC24EP®
features integrated modules such as stereo MP3
codec, TFT 320x240 touch screen display,
accelerometer, USB connector, audio connector,

MMC/SD card slot, 8 Mbit ash memory, 2x26

connection pads and other. It comes pre­programmed with USB HID bootloader, but can
also be programmed with external programmers,
such as mikroProg™ or ICD2/3. Mikromedia is

compact and slim, and perfectly ts in the palm

of the hand, which makes it convenient platform
for mobile devices.

Battery 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.

USB power supply

You can apply power supply to the board
using MINI-B USB cable provided with
the board. On-board voltage regulators
provide the appropriate voltage levels
to each component on the board. Power

Programming with mikroBootloader

You can program the microcontroller with bootloader which
is pre-programmed into the device by default. To transfer

.hex le from a PC to MCU you need bootloader software

(mikroBootloader USB HID) which can be downloaded from:

http://www.mikroe.com/eng/downloads/get/1858/
mikrobootloader_pic24ep_usbhid_v200.zip

After software is downloaded unzip it to desired location and
start mikroBootloader USB HID software.

step 1 – Connecting mikromedia

01

Figure 3-2: USB HID mikroBootloader window

To start, connect the USB cable, or if already connected

01

press the Reset button on your mikromedia board. Click the

”Connect” button within 5s to enter the bootloader mode,

otherwise existing microcontroller program will execute.

Figure 3-9:
Connecting mikroProg™ to mikromedia™

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.

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.

Page 16

mikroProg™ is a

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.

Programming with

ICD2® or ICD3® programmer

The microcontroller can be also programmed with ICD2®

or ICD3® programmer. These programmers connects

with mikromedia board via ICD2 CONNECTOR BOARD.

Figure 3-12:

Connecting ICD2®

or ICD3® programmer

Figure 3-11:

Placing ICD2®

connector

In order to enable the ICD2® and ICD3® programmers to be connected to the

mikromedia board, it is necessary to provide the appropriate connector such as the

ICD2 CONNECTOR BOARD. This connector should be rst soldered on the CN5 connector.

Then you should plug the ICD2® or ICD3® programmer into it, Figure 3-11.

4. Reset Button

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).

NOTE

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.

Board is equipped with 8MHz crystal oscillator

(X1) 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. Board also contains 32.768kHz Crystal oscillator

(X3) which provides external clock for internal RTCC module.

oscillator (X1)

The use of crystal in all other schematics is implied even if it is purposely
left out because of the schematics clarity.

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.

7. Touch Screen

The development system features a TFT 320x240 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 TFT display is capable of showing
graphics in 262.144 die rent colors.

10. Accelerometer

On board ADXL345 accelerometer is used to
measure acceleration in three axis: x, y and z. The

accelerometer function is dened by the user in the

program loaded into the microcontroller. Communication
between the accelerometer and the microcontroller is performed
via the I2C interface.

module

You can set the accelerometer
address to 0 or 1 by re-soldering the
SMD jumper (zero-ohm resistor) to the
appropriate position. Jumper is placed
in address 1 position by default.

Since multimedia applications are
getting increasingly demanding, it is
necessary to provide additional memory
space to be used for storing more data.

The ash memory module enables the

microcontroller to use additional 8Mbit

ash memory. It is connected to the

microcontroller via the Serial Peripheral
Interface (SPI).

Pads HDR2

Most microcontroller pins are available for further connectivity via two 1x26 rows of connection
pads on both sides of the mikromedia board. They are designed to match additional shields,
such as Battery Boost shield, Gaming, PROTO shield and others.

15. mikromedia accessories

We have prepared a set of
extension boards pin-compatible
with your mikromedia, which
enable you to easily expand
your board basic functionality.
We call them mikromedia

shields. But we also oer other

accessories, such as Li-polymer
battery, stacking headers, wire

What’s next?

You have now completed the journey through each and every feature of mikromedia for PIC24EP board. You got to know it’s modules and
organization. Now you are ready to start using your new board. We are suggesting several steps which are probably the best way to begin. We

invite you to join the users of mikromedia™ brand. You will nd very useful projects and tutorials and can get help from a large ecosystem of

users. Welcome!

Compiler

You still don’t have an appropriate compiler? Locate dsPIC/PIC24® compiler that suits you
best on the Product DVD provided with the package:

DVD://download/eng/software/compilers/

Choose between mikroC™, mikroBasic™ and mikroPascal™ and download fully functional

demo version, so you can begin building your rst applications.

Projects

Once you have chosen your compiler, and since you already got the board, you are ready to start writing your rst

projects. Visual TFT software for rapid development of graphical user interfaces enables you to quickly create your
GUI. It will automatically create necessary code which is compatible with mikroElektronika compilers. Visual TFT is
rich with examples, which are an excellent starting point for your future projects. Just load the example, read well
commented code, and see how it works on hardware. Visual TFT is also available on the Product DVD.
