Audio and Video Development Boards
To follow the experiments of the most advanced chapters in the book there is now a professionally manufactured
The AV16/32 board
A PICTail Plus(tm) board and the solution of choice if you already own an Explorer 16 or a PIC32 I/O expansion board. It is compatible with the PIC24 and dsPIC series of microcontrollers and digital signal controllers . Available as a bare PCB or a simple kit (no SMD components).
The AV16/32 Board is also compatible with the PIC32 I/O Expansion Board.
You will connect with:
- 1/8” Stereo Audio Output Jack (J1)
- SD Card Interface (J2)
- PS/2 Keyboard Input Port (J3)
- Composite Video Output (J4)
- VGA (monochrome) Output (J5)*
The stereo output circuit uses active 2nd order filter circuits to produce quality audio using two PWM outputs. The signal can be connected to high impedance headphones, PC speakers, or a PC sound card input.
The SD card socket connects to one of the SPI channels on the PIC.
The PS/2 keyboard input can be connected to the Change Notification (CN) input pin, the Input Capture (IC) input pin or a generic digital I/O.
The video output uses an Output Compare channel and a SPI channel to produce monochrome NTSC (or PAL) composite video.
Finally a VGA connector will allow you to obtain a (monochrome) high resolution output directly on a standard computer screen.

The folks at eflightworks (http://www.eflightworks.net/) have created a series of exciting development boards designed specifically to support the those among you who own a PIC32 Starter Kit or a PIC32 PIM...
The AV-32 board, is designed to connect directly to a PIC32 Starter board (via the Hirose 120pin connector) and provide:
- Composite Video Output
- VGA Video Output (!)
- Stereo Sound Output
- MicroSD connector
- 16x 2 alphanumeric LCD
- Nokia knock off Color LCD display connector (!)
- Serial EEPROM
- Serial Flash
- RS232 Serial Port
- 9-16V additional power supply input

The AV-32/P board is designed to connect directly to a 100 pin PIC32 PIM (Plug-in Module).
It provides the same expansion options of the basic AV-32 board but it will require the use of a separate JTAG or ICD programmer/debugger.
Notice that any Microchip 100pin PIM (PIC24 and dsPIC included) can be used!
