SoftModem
====
SoftModem is a wired, low-cost and platform independent solution for communication between an Arduino and mobile phones. It uses the phone's audio jack and Bell 202 modem-like FSK encoding with up to 1225 bit/s. Check out this [blog post](https://github.com/arms22/SoftModem/blob/master/http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Farms22.blog91.fc2.com%2Fblog-entry-350.html&sl=auto&tl=en).

### Install via Arduino Library Manager
Open the Arduino Library Manager from the menu: `Sketch → Include Library → Manage Libraries...`.
Then search for 'SoftModem' and click install.
### Manual install
Create a folder 'SoftModem' inside your `libraries` folder and place these files there.
## Supported Boards
- ATmega328: Arduino Uno / Nano / Pro / Pro Mini / Fio
- ATtiny85, ATmega32U4: not implemented yet, contributions welcome!

## Usage
This is an example sketch that forwards data to/from the serial port.
```Arduino
#include
SoftModem modem = SoftModem();
void setup() {
Serial.begin(115200);
Serial.println("Booting");
delay(100);
modem.begin();
}
void loop() {
while(modem.available()){
int c = modem.read();
if(isprint(c)){
Serial.print((char)c);
}
else{
Serial.print("(");
Serial.print(c,HEX);
Serial.println(")");
}
}
if(Serial.available()){
modem.write(0xff);
while(Serial.available()){
char c = Serial.read();
modem.write(c);
}
}
}
```
### Notes
SoftModem uses Timer2, therefore you can not make use of the `analogWrite()` function for pins 3 and 11 in your sketch.
### Hardware
A shield is available [here](https://github.com/arms22/SoftModem/blob/master/https://www.switch-science.com/catalog/600/) or [here](https://github.com/arms22/SoftModem/blob/master/http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_92&products_id=2199). You can also build your own. Here is the schematic:
