Propeller Backpack

El nuevo generador de video es capaz de superponer video desde una señal de entrada y enviar a un TV usando simples conectores RCA. Numerosos fabricantes han optado por incorporar nuestro nucleo en aplicaciones de video obteniendo imagenes de alta calidad.

Se pueden generar caracteres de distintos tamaños , en distintos colores y en distintas ventanas.

Tambien se puede generar texto y sonido gracias a la potencia de microcontrolador Propeller incluido en esta placa.

The Propeller Backpack is a compact, multipurpose Propeller-based module that is optimized for audio and video applications. Out of the box, and without programming, it serves as a video character display for your BASIC Stamp (or other compatible controller). Using one of our 3-wire Extension Cables, you can plug the Backpack into a standard 3-pin servo header and communicate using a simple serial protocol. Any NTSC video monitor plugged into the Backpack’s A/V connector will then display the characters sent by your program – in color, in selectable windows, and with selectable character sizes.

The Propeller Backpack is also a fully-capable Propeller development platform, which you can program with Parallax’s free Propeller Tool software. Uploading programs to it is a snap, either by using the free LoadBP software via any BASIC Stamp, or directly with the optional Prop Plug. The Propeller Backpack works in conjunction with your own firmware, or that from the Propeller Object Exchange (OBEX). The Propeller Backpack is expandable, too. The onboard 12-pin socket makes it compatible with Parallax’s complete line of plug-in daughterboards.

Features:

• External interface
• 1/8” stereo phone jack for A/V signals, 3-pin servo header for power and serial I/O, 4-pin Prop Plug header, 12-position daughterboard socket
• Onboard Propeller chip and 10MHz crystal for up to 80MHz operation
• Double-size (64K x 8) EEPROM for programs and data
• Onboard sigma-delta analog input circuitry (2 channels)

Application Ideas:

• Provide programmable character overlays on top of an incoming video signal
• Send and receive data by radio at 1200 baud, using the AFSK modem software from the OBEX and the built-in push-to-talk circuitry
• Generate line-level stereo audio output or simultaneous audio and video output
• Accept line-level audio input with or without simultaneous video output
• Generate synthetic speech
