Cannot get Radioheads ASK to run on Atmega1284

Projects Networking, Protocols, and Devices

Hi,
I have searched and only found a reference on the Radiohead list saying it now supports Atmega1284, but no details.

I have tried with just their simple ASK rx example below, with various pin numbers on the Bobduino mini 1284 board, and get no response when transmitter sends.
With a similar receiver on a promini board it receives fine.

Any suggestions?

void setup()
{
    Serial.begin(9600);    // Debugging only
    if (!driver.init())
         Serial.println("init failed");
}

void loop()
{
    uint8_t buf[RH_ASK_MAX_MESSAGE_LEN];
    uint8_t buflen = sizeof(buf);

    if (driver.recv(buf, &buflen)) // Non-blocking
    {
    int i;
 Serial.println("Got ");
    // Message with a good checksum received, dump it.
    driver.printBuffer("Got:", buf, buflen);
    }
}
