class B productProduct complies with the Class B limit of EN 55022 and can be used in the domestic, residential, commercial and industrial environments.

1. 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 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.

Programming with mikroBootloader

Figure 3-2: USB HID mikroBootloader window

step 1 – Connecting mikromedia

01

01 In order to start, connect the USB cable or (if already connected) press the Reset button on your mikromedia board. Click the Connect button within 5s to enter the bootloader mode, otherwise the existing microcontroller program will be executed.

Microcontroller is preprogrammed with USB HID Bootloader, which

can be used to upload new device firmware. To transfer firmware

.HEX file from a PC to MCU you need to use mikroBootloader USB

HID application, which can be downloaded from:

Upon download, unzip it to desired location and start the mikro-

Bootloader application:

http://www.mikroe.com/downloads/get/1682/mikrobootloader_pic18f87j50_v210.zip

step 3 – Selecting .HEX file step 2 – Browsing for .HEX file

Select .HEX file using open dialog window.

Click the Open button.

step 4 – Uploading .HEX file

Click the OK button after uploading is finished. The board will be automatically reset and after 5 seconds your new program will be executed.

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™

Figure 3-9: Connecting mikroProg™ to mikromedia™

mikroProg Suite™ for PIC® Software

Figure 3-10: Main Window of mikroProg Suite™ for PIC® programming 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.

The microcontroller can be also

programmed with ICD2® or ICD3®

programmer. These programmers

connects with mikromedia board

via ICD2 CONNECTOR BOARD.

Programing with

ICD2® or ICD3® programmer

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.

or ICD3® programmer

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).

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.

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

The mikromedia™ for PIC18FJ® features stereo audio codec VS1053. This

module enables audio reproduction by using stereo headphones connected

to the system via a 3.5mm connector CN2. All functions of this module are

controlled by the microcontroller over Serial Peripheral Interface (SPI).

10. Accelerometer

On board ADXL345 accelerometer is used

to measure acceleration in three axis: x, y and

z. The accelerometer function is defined by the

user in the program loaded into the microcontroller.

Communication between the accelerometer and the

microcontroller is performed via the I2C interface.

Figure 10-1: Accelerometer 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.

11. Flash Memory

Since multimedia applications are getting increasingly

demanding, it is necessary to provide additional memory

space to be used for storing more data. The flash memory module

enables the microcontroller to use additional 8Mbit flash memory. It is

connected to the microcontroller via the Serial Peripheral Interface (SPI).

12. Pads

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. Pads with underlined silkscreen

markings have multiple functions (see the complete schematic for more information).

enable you to easily expand

your board basic functionality.

We call them mikromedia

shields. But we also offer other

accessories, such as Li-polymer

You still don’t have an appropriate compiler? Locate PIC® compiler that suits you best on our site:

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

demo version, so you can begin building your first applications.

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

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 our site:

You have now completed the journey through each and every feature of mikromedia™ for PIC18FJ® 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 find very useful projects and tutorials and can get help from a large ecosystem

of users. Welcome!
