®

The mikromedia+ for PIC32MX7® is a compact development system which allows development of devices with multimedia contents. The central part of the system is a 32-bit 100-pin

PIC32MX795F512L microcontroller. The mikromedia+ for

PIC32MX7® feature lots of on board modules such as stereo MP3 codec, 4.3’’ TFT 480x272 touch screen display, port expander, accelerometer, microSD card slot, buzzer, IR receiver, RGB LED diode, PIN photodiode, temperature sensor, 2.4GHz

RF transceiver, Ethernet transceiver, 8 Mbit ash memory,

Li-Polimer battery charger etc. The board also contains MINI-B USB connector, power screw terminals, 2x5 mikroProg™ connector, two 1x26 connection pads, ON/OFF switch and other. It comes pre-programmed with USB HID bootloader, but can also be programmed with mikroProg™ for PIC®, dsPIC® and

PIC32® external programmer. mikromedia is compact and slim,

and perfectly ts in the palm of your hand, which makes it a

convenient platform for mobile and other multimedia devices. We have also prepared a mikromedia+ SHIELD for PIC32MX7 extension board which enables you to easily expand the functionality of your board.

1. Power Supply

Figure 1-1: USB power supply

The mikromedia+ for PIC32MX7® board can be powered in three dierent ways: via USB connector using MINI-B USB cable provided with the board (CN4), via battery connector using Li-Polymer battery (CN5) or via screw terminals using laboratory power supply (CN3). After you plug in the appropriate power supply turn the power switch ON (SW1). The USB connection can provide up to 500mA of current which is more than enough for the operation of all on-board modules and the microcontroller as well. If you decide to use external power supply via screw terminals, voltage levels must be within 5-12 V D C range. Power LED ON (GREEN) indicates the presence of power supply. On-board battery charger circuit MCP73832 enables you to charge the battery over USB connection or via screw terminals. LED

diode (RED) indicates when battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.

mikroProg Suite™ for PIC® Software

PIC32

The mikroProg™ programmer requires special programming software called

mikroProg Suite™ for PIC®. It can be

used for programming all Microchip® microcontroller families, including PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32®. Software has intuitive interface and SingleClick™ programming technology. Download the latest version of mikroProg Suite™ and 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.

5. Crystal Oscillators and 2.048V Reference

The board is equipped with 01 16MHz

crystal oscillator (X4) circuit that

provides external clock waveform to the microcontroller OSC1 and OSC2 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 board also contains 02 32.768kHz crystal

oscillator (X5) which provides external clock for internal RTCC

module. Microcontroller ADC requires an accurate source of reference voltage signal. That is why we provide the external 03 voltage reference to the microcontroller VREF pin which is 2.048V.

6. Port Expander

Figure 6-1: Port Expander

mikromedia+ for PIC32MX7®

features a 16-bit I/O port

expander module MCP23S17 which

communicates with PIC32MX795F512L

microcontroller via SPI serial interface. This

module enables you to expand the number of

microcontroller I/O pins with two 8-bit I/O ports (PORTA

and PORTB). Each of them consists of registers for input, output

and polarity selection. In addition, the MCP23S17 module contains

interrupt and reset pins and has 25mA sink/source capability per I/O pin.

7. microSD Card Slot

02

01

The board contains 01 microSD card slot for using 02 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. Ferrite and capacitor are provided to compensate the voltage and current glitch that can occur when pushingin and pushing-out microSD card into the socket. Proper insertion of the microSD card is shown in Figure 7-1.

8. Touch Screen

The development system features a 4.3‘‘

TFT 480x272 display covered with a

resistive touch panel. Together they

form a functional unit called a touch

screen, Figure 8-1. It enables data to be

entered and displayed at the same time.

The TFT display is capable of showing

graphics in 256K die rent colors.

MP3 codec

02

mikromedia+ for PIC32MX7® features stereo audio codec 01 VS1053. This module enables audio reproduction and sound recording by using 02 stereo headphones with

microphone connected to the system via a 03 3.5mm connector CN2. All functions of this

module are controlled by the microcontroller over Serial Peripheral Interface (SPI). IN and OUT channels are also provided on side headers.

Figure 12-1: Accelerometer module

On board ADXL345 accelerometer is used to measure acceleration in three

axis: x, y and z. Most common use is to determine the screen orientation,

but there are many other elds of usage. Communication between

the accelerometer and the microcontroller is performed

through I2C interface. There is an option to select

the alternate accel address with jumper J3.

Since multimedia applications are getting increasingly demanding,

it is necessary to provide additional memory space 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).

Figure 15-1: Ethernet transceiver module

The development system features an Ethernet transceiver module ideal for local area networking (LAN). Communication over Ethernet is based on data packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. If you want to establish connection with computer, router or other devices you need to use standard RJ-45 connector which is provided on mikromedia+ SHIELD for PIC32MX7®. Communication lines are also provided over side headers.

16. Buzzer

The board is also equipped with piezo buzzer. It is an electric component which can be used to create sound when is provided with electrical signal. This is usually a PWM signal coming from a microcontroller pin. Frequency of the signal

determines the pitch of the sound and duty cycle of the signal can be used to increase or decrease the volume.

The board also contains other useful peripherals such as 01 PIN photodiode, 02 IR receiver, 03 RGB led diode and 04 analog

temperature sensor. PIN photodiode is a type of photo detector. It has high sensitivity and response speed. It is connected to the

microcontroller analog pin RB8. IR receiver is used in infrared remote control systems. The demodulated output signal obtained from

IR module can be directly decoded by a microcontroller. Many of standard data formats are supported. RGB (Red, Green, Blue) diode

can be used as a light indicator. Each color is driven separately by transistor. The analog temperature sensor converts temperature to

analog voltage. It is directly connected to the microcontroller RB9 analog pin. Temperature measurement range of mikromedia+ for

PIC32MX7® board is from -20° C to 70° C.

22. What’s next?

Your journey through each and every feature of mikromedia+ for PIC32MX7® board ends here. You got to know it’s modules and organization. Now you are ready to use it. We are suggesting several steps which are probably the best way to begin with. 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 PIC® 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 will enable 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 check how it works on hardware. Visual TFT is also available on the Product DVD.
