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 of 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

battery charging. Led is off when battery is full. 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

You can program the microcontroller with bootloader which

is preprogrammed into the device by default. To transfer

.hex file from a PC to MCU you need bootloader software

(mikroBootloader USB HID) which can be downloaded from:

Upon download, unzip it to desired location and start the

mikroBootloader application:

http://www.mikroe.com/downloads/get/1704/mikro-bootloader_pic24_usbhid_v210.zip

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.

Click the OK button after uploading is finished and wait for 5 seconds. Board will automatically reset and your new program will execute.

Page 16

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.

Figure 3-9: Connecting mikroProg™ to mikromedia™

Page 17

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

PIC24

Page 18

Figure 3-11:Placing ICD2®

connector

The microcontroller can be also programmed with ICD2® or ICD3® programmer. These programmers connects

with mikromedia board via ICD2 CONNECTOR BOARD.

Programming 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.

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).

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.

5. Crystal Oscillator

Figure 5-1:Crystal oscillator module (X1)

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

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 diffe rent colors.

10. Accelerometer

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.

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.

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.

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 offer other

accessories, such as Li-polymer

battery, stacking headers, wire

jumpers and more.

You still don’t have an appropriate compiler? Locate dsPIC/PIC24® 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 PIC24® 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!
