# TeleShield
This is an RF interface board for use with [Arduino](http://arduino.cc)
systems. It provides the equivalent of a [TeleDongle](../TeleDongle)
plus [Bluetooth](http://www.bluetooth.com), plus a microSD socket for
data storage.
The RF filter components are set for use in the vicinity of 435 Mhz.
These are photos of the first prototype:

## Features ##
### User View ###
* can be used as an
[Arduino shield](http://www.arduino.cc/en/Main/arduinoShields)
or as a USB peripheral
* 70cm ham-band transceiver compatible with [Altus Metrum](../) products,
programmed for 38k4 GFSK data rate with forward error correction
* Bluetooth
* micro USB interface
* 4 pin Tyco MicroMaTch connector for debug and flash programming
* 8 pin Tyco MicroMaTch connector supports serial or SPI interface
* micro SD socket for Arduino data storage (not connected to CC1111!)
### Developer View ###
* [TI CC1111F32](http://focus.ti.com/docs/prod/folders/print/cc1111f32.html) Low Power RF System-on-Chip
* Sub-1Ghz transceiver
* 8051 MCU
* 32k Flash
* 4k RAM
* USB 2.0
* 6 12-bit analog inputs (11 bits with single-ended sensors)
* 2 channels of serial I/O
* digital I/O
* interfaced to Arduino via async serial plus two handshake pins
* Rayson BTM-182 (Bluetooth SPP module) using async to CC1111
* micro SD card socket interfaced to the Arduino via SPI
* 150mA 3.3V LDO regulator
* can take input from either USB or the unregulated Arduino input
* input and output appear on 8-pin companion connector
* Software Features
* Written mostly in C with some 8051 assembler
* Runs from on-chip flash, uses on-chip RAM
* USB serial emulation for data interface
* Tools Used
* [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
* [SDCC](http://sdcc.sourceforge.net/) compiler and source debugger
* Licenses
* The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)
* The software is licensed [GPL version 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html)
## Artifacts ##
There is a single manual for all Altus Metrum products,
which is available in [html](../AltOS/doc/altusmetrum.html) and
[pdf](../AltOS/doc/altusmetrum.pdf) formats.
The hardware design current gEDA files are available from
[git.gag.com](http://git.gag.com) in the project
[hw/teleshield](http://git.gag.com/?p=hw/teleshield;a=summary).
## Future Plans ##
The prototype v0.1 boards work fine. Feedback from showing them at the
Arduino mini-conference at LCA 2012 resulted in elimination of the Bluetooth
interface. Updated boards have not been built yet, but
[schematic and artwork files](v0.2/) are available for review and comment.
If there is sufficient interest, we will produce some. Exactly if or
when that will happen and what they might cost are not known yet.
