加入技術交流群
The Multimedia Expansion Board (MEB) provides PIC32 Starter Kit, dsPIC33E USB Starter Kit or PIC24E USB Starter Kit users with an integrated yet flexible solution for development of high impact user interfaces. The board comes with a 3.2 Color TFT touch-screen QVGA display, an onboard FCC certified WiFi module, a 24-bit stereo audio code, a three-axis accelerometer, a joystick and a MicroSD memory card slot. Simply connect any DM320001, DM320003-2, DM320004, DM330012 and DM240012 Starter Kit to the MEB and you’re ready to develop, program and debug code for the user interface features. Demo software for the MEB may be downloaded below and is also contained within the Microchip Application Library, including software for the joystick, accelerometer, CPLD and more.
1. 3.2 inch (8.1 cm) QVGA touch screen display with backlight.
2. Five user-controlled LEDs.
3. Four-way joystick (S2).
4. Fire button (S1).
5. Headphone jack.
6. Line output jack.
7. Microphone input jack.
8. Power LED.
9. I/O expansion connector
1. Solomon Systech Graphics Controller (SSD1926).
2. microSD card slot.
3. Regulated 3.3V and 1.8V power supply for powering the board via a starter kit or
9-14V power supply.
4. Accelerometer and temperature sensor (BMA150).
5. 24LC08 EEPROM.
6. 2 MB SPI Flash (SST25VF016).
7. 24-bit stereo audio codec (WM8731).
8. CPLD for SPI and Chip Select configuration.
9. PIC32 starter kit connector.
10. Integrated 802.11 wireless connectivity.
