Propeller Propeller Backpack
El nuevo generador de video es capaz de superponer
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 (# 805-00001 or # 805-00002 ), 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 (# 32201 ). 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
