Introduction to mikromedia for ATmega

The mikromedia for ATmega 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 the 8-bit ATmega1280 microcon-

troller. The mikromedia for ATmega features

integrated modules such as stereo MP3 codec, TFT 320x240 touch screen display, accelerometer,

USB connector, audio connector, MMC/SD card

slot, 8 Mbit flash memory, 2x26 connection pads

and other. It comes pre-programmed with USB-

UART bootloader, but can also be programmed

with external AVR JTAGICE mkII. Mikromedia is

compact and slim, and perfectly fits in the palm

of the hand, which makes it convenient platform

for mobile devices.

1. Power supply

You can apply power supply to the board

using MINI-B USB cable provided with

the board. On-board voltage regulators

will make sure that are avaibale the

appropriate voltage levels to each part

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. CHARGE LED (RED) will indicate

battery charging. Led is off when battery is full. Charging

current is ~250mA and charging voltage is 4.2V DC.

microcontroller

The microcontroller can be programmed in two ways:

Page 12 Page 13

Programming with mikroBootloader

You can program the microcontroller with UART bootloader

which is preprogrammed into the device by default. To transfer

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

(mikroBootloader) which can be downloaded from:

After software is downloaded unzip it to desired location and

start mikroBootloader software.

http://www.mikroe.com/eng/downloads/get/1822/mikrobootloader_atmega1280_v210.zip

Figure 3-2: mikroBootloader window

mikroBootloader software

01 When you start mikroBootloader software, a window shown on Figure 3-2 should appear.

The microcontroller can be

programmed with an external pro-

grammer (AVR JTAGICE mkII or other

supported programer with JTAG

interface). The external programmer

is connected to the development

system via pads marked with

JTAG, Figure 3-11. In order to

connect the external programmer

to the development system, it is

necessary to solder the 2x5 male

headers provided with the product

to JTAG pads

Programing with external

programmer

Figure 3-11:mikroProg™ JTAG

connectorIf bootloader program is accidently erased you can upload it again via AVR

JTAGICE mkII programmer. Program mikroMedia for ATmega Bootloader Firmware.hex

can be found under Firmware folder (page 12)

Board is equipped with two reset buttons. First is located at the back side of

the board (Figure 4-1), and second one is at the top of front side (Figure 4-2).

If you want to reset the circuit, press either of two buttons. 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).

ATmega1280 is equipped with internal 128kHz RC oscillator that can provide

base frequency. Board also contains 8MHz crystal oscillator (X1), which is the

most optimal because chip is powered by 3.3V supply. Since chip does not

have integrated PLL, maximum operating frequency is also 8MHz, which is just

enough for your multimedia applications.

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.

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 data in 262.144

diffe rent colors.

Mikromedia contains USB MINI-B connector which is positioned next to the battery connector. FT232RL USB-UART IC enables you to implement

UART serial communication functionality via USB cable, since ATmega1280 does not support USB protocol. Before connecting the board,

make sure that you have FTDI drivers installed on your computer. Rx/Tx LED flashes when USB and controller communicate.

10. Accelerometer

On board ADXL345 accelerometer, among other

features, can be 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.

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 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 schematics for more information).

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 AVR® compiler that suits you best on

the Product DVD provided with the package:

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 the Product DVD.

You have now completed the journey through each and every feature of mikromedia for ATmega 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!
