1. Copy the SoftModem-004.zip in library
2. Copy the example in a new file
3. Compile with arduino 1.0 ide

Compilation fails with error:

In file included from softmodem.cpp:1: /Applications/Arduino.app/Contents/Resources/Java/libraries/SoftModem/SoftModem.h:72: error: conflicting return type specified for 'virtual void SoftModem::write(uint8_t)' /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/Print.h:48: error: overriding 'virtual size_t Print::write(uint8_t)'

This is the example:

include <SoftModem.h>

include <ctype.h>

SoftModem modem;

void setup() { Serial.begin(57600); delay(1000); modem.begin(); }

void loop() { while(modem.available()){ int c = modem.read(); if(isprint(c)){ Serial.println((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); } } }

hello! I'm having the same error. Do you already have the solution? Thank you

This is a patch which update the compatibility for the old and the new arduino.

Ok forget my previous comment, here is a patched version of SoftModem, worked perfectly , thanks mattia :)

Had the same issue, resolved by the above patch. Thanks for contributing.

Hello I have had similar problems as above. Would someone mind reposting the patch? Google says the link is invalid. Thanks for the info!

I tried to use SoftModem with arduino pro mini (3.3v, 8MHz), but the demodulation process doesn´t work. When i use the arduino uno everything work very fine. Could you help me please.

With arduino 1.0.1 I get the following compile errors using the patched version:

Has anyone else had this problem?

Thanks!

Hello, I'm trying to get new high and low frequencies, but demodulation doesn't work.Could you give me a tip?
