2. Programming with bootloader

For programming, microcontroller use bootloader program which

is preinstaled in to MCU memory. To transfer .hex file from a PC to

MCU you need bootloader software (mikroBootloader USB HID)

which can be downloaded from:

After software is downloaded unzip it to desired location and

start mikroBootloader USB HID software.

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

way of entering and displaying data

depends on the program loaded into

the microcontroller. The TFT display

is capable of showing data in

262.000 diffe rent colors.

Since multimedia applications are getting increasingly demanding, it is

necessary to provide additional memory space to be used for storing programs

by the microcontroller. 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).

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a built-in

memory module used for storing data that should be saved when power goes

off. The 24AA01 circuit may store 1Kbit data and uses serial I2C communication

to exchange data with the microcontroller.

Figure 9-2: microSD card

There is a built-in MMC/SD slot for MMC/SD card provided on the development system. It

enables the system to additionally expand available memory space. The Serial Peripheral

Interface (SPI) is used for communication between the microcontroller and MMC/SD card.

The Multimedia Board features an

audio module providing an interface for

a microphone and stereo headphones. This

module enables audio recording via a mono

microphone. The microphone is connected to

the system via a 3.5mm connector CN7. Stereo

headphones are used for audio reproduction. They are

connected to the system via a 3.5mm connector CN6. For

the proper use of microphone and headphones, it is necessary

to write a program and load it into the microcontroller. In

addition to the audio recording and reproduction, the audio module

can also generate a side tone in the headphones. Volume as well as

other functions of this module are controlled by the microcontroller

from within the software using serial I2C communication. Communication

between the audio module and the microcontroller is performed via the Serial

Peripheral Interface (SPI).

12. USB connectors

MultiMedia Board for PIC32MX7 have two USB

connectors: USB MINIB and USB HOST.

USB MINIB represents OTG device which is used for connection

with a PC. This USB connector is used for MCU programming

via bootloader software.

Figure 12-1: Inserting the USB MINIB cable

USB HOST (USB A) connector is used for attaching

another devices to MMB for PIC32MX7 board like

printer, scanner, keyboard etc. Bare in mind that is

necessary to write a program which will control

these devices.

An LED (Light-Emitting Diode) is a highly efficient electronic

source of light. When connecting LEDs, it is necessary to use

a current limiting resistor. A common LED diode voltage is

approximately 2.5V, while the current varies from 1 to 20mA

depending on the type of LED. The Multimedia Board uses LEDs

with current I=1mA.

There are three LEDs on the Multimedia Board that can be assigned a signal

function. LEDs are connected to the following I/O microcontroller pins: LD0

- RA0, LD1 - RA1 and LD2 - RD9. The LED marked POWER indicates when

the system is turned on, whereas the diode marked MMC/SD is used to

indicate memory card activity.

Page 36 Page 37

UART (Universal Asynchronous Receiver/Transmitter)

is one of the most common ways of exchanging data

between a PC and peripheral devices. The RS-232 serial

communication is performed via a 9-pin SUB-D connector and

the microcontroller’s UART module.

14. RS-232 module

The development board features the RS-232 module which

communicates with MCU via UART communication.

Due to the Ethernet module, the

development system can access the LAN

network in order to establish communication

with remote devices. The Ethernet module operates

in compliance with the IEEE 802.3/802.3u and

ISO 802-3/IEEE 8021.3 (10BASE-T) standards. The

development system is connected to the LAN network via

a standard RJ45 ethernet connector.
