mikromedia for PIC32: PIC32MX460F512L, TFT LCD, Accelerometer US$99.00

mikromedia for PIC32: PIC32MX460F512L, TFT LCD, Accelerometer

The mikromedia for PIC32 is a compact development system with lots of on-board peripherals which allow development of hand-held devices with multimedia content. The central part of the system is the 32-bit Microchip PIC32MX460F512L microcontroller. The mikromedia for PIC32 features integrated modules such as stereo MP3 codec, TFT 320240 touch screen display, accelerometer, USB connector, audio connector, MMC/SD card slot, 8 Mbit Flash memory, and more. The board features a front-facing reset button, battery charger circuit for Li-Polymer batteries, crystal oscillator, and connection pads for all other available pins. It is compatible with all mikromedia shields (see options below) and can be plugged directly into the mikromedia WorkStation.

A color user manual and code examples are included. The board comes pre-programmed with a USB bootloader, so you won't have to spend a penny more on external programmers. If you do want to, pins pads are available for using a mikroProg for PIC or ICD2/3 (with adapter).

All unused microcontroller pins are available via pads along the sides of the board. The board measures 81.2 60.5 mm (3.19 2.38 inches).

PIC32 Multimedia Board Features

PIC32MX460F512L microcontroller

This high-performance 32-bit microcontroller with its integrated modules in combination with the on-board modules is ideal for multimedia applications.
  • 80 MHz, 1.56 DMIPS/MHz (120 MIPS), 32-bit MIPS M4K core
  • 512 KB of program memory plus 12K boot Flash
  • 32K RAM (can execute from RAM)
  • 4-channel General Hardware DMA controller
  • CPU operating voltage 2.3V to 3.6V
  • 85 I/O pins
  • SPI, I2C, A/D
  • Max. I2C speed 400 kHz
  • 16-bit, 32-bit Digital Timers
  • Internal Oscillator 8 MHz, 32 kHz
  • RTCC
  • Flash pre-fetch module with 256-byte cache
  • Can lock instructions or data in cache for fast access
  • Programmable vector interrupt controller, etc.

USB power supply

You can apply power to the board using the provided mini-B USB cable. On-board voltage regulators will provide the appropriate voltage levels to each part of the board. The Power LED will indicate the presence of power supply.

Battery power supply

You can also power the board using a Li-Polymer battery via the on-board battery connector. An MCP73832 battery charger circuit enables you to charge the battery over USB connection. A red LED indicates when the battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.

Programming with bootloader

For programming the microcontroller, you can use a bootloader program which is pre-installed in the MCU memory. To transfer a .hex file from a PC to the MCU, you can use the free mikroBootloader application. The board has a mini-USB connector and ships with a cable to connect to your PC.

Programming with external programmer/debugger

In case you want to remove the USB bootloader, need to re-install it, or want to perform in-circuit debugging, the microcontroller can be programmed with an external in-circuit programmer/debugger (not included). The board has pads for installing programming headers compatible with the mikroProg for PIC or the ICD2 Connector Board.

Reset Button

The board is equipped with a reset button on the LCD side so it can be available to the user if the mikromedia board is placed in an enclosure. The other side of the board has pads for installing a second reset button if needed.

Crystal Oscillator

The board is equipped with an 8 MHz crystal oscillator circuit that provides an external clock waveform to the microcontroller's OSC pins. This base frequency is suitable for further clock multipliers and ideal for generation of the necessary USB clock, which ensures proper operation of the bootloader and your custom USB-based applications. The board also contains a 32.768 kHz crystal oscillator which provides external clock for the internal RTCC module.

microSD Card Slot

The board contains a 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. Max. microSD SPI speed is 20 MHz.

LCD with Touch Screen

The development system features a TFT 320240 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. Current consumption with backlight on is 113 mA (backlight consumption is 42 mA). The TFT display is capable of showing data in 262,144 different colors. A stylus is sold separately; see the options below.

Audio Module

mikromedia for PIC32 features a VS1053 audio controller. This module enables audio reproduction by using stereo headphones connected to the system via the 3.5mm connector CN2. All functions of this module are controlled by the microcontroller over Serial Peripheral Interface (SPI). Max. audio codec SPI speed is 3.33 MHz.

USB Connection

The PIC32MX460F512L has an integrated USB module which enables you to implement USB communication functionality to the mikromedia board. Connection to a target USB host is achieved with a mini-B USB connector.


The on-board ADXL345 accelerometer can be used to measure acceleration in three axes: x, y, and z. The accelerometer's function is defined by 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. This jumper is placed in address 1 position by default.

Flash Memory

The M25P80 Flash memory module enables the microcontroller to use an additional 8Mbits of Flash memory. It is connected to the microcontroller via the Serial Peripheral Interface (SPI). Max. serial Flash SPI speed is 40 MHz.

Software Examples

The code example ZIP file that you can download below contains the following example software, both as ready-to-load compiled code and as source code written in mikroC, mikroBASIC and mikroPascal. The source codes provide detailed explanatory comments.
  • Demonstration of ADXL345 three-axis accelerometer. Values from accelerometer are shown on the TFT display.
  • Demonstration of microSD card slot and MMC FAT16 library.
  • Demonstration of Touch Panel. Creates a simple calculator.
  • Demonstration of communicating with VS1053 codec. Reads MP3 file from MMC and sends it to VS1053E for decoding and playback.
  • Demonstration of USB module. Creates USB HID communication, and echoes back any message sent to it.
  • Demonstration of M25P80 Serial Flash. Connects via SPI, writes a byte and an array of bytes, then reads them back.
  • Demonstration of TFT LCD. Displays a picture.
