Your code is almost a textbook example for what <i>not</i> to do with multiple ports. For your application I think you'd roughly want to do something like: <pre> void loop() { port1.listen(); // wait for several seconds or until you get a valid code on port 1 ... port2.listen(); // wait for several seconds or until you get a valid code on port 2 // } </pre> @Marc,

Read carefully the section on “Using Multiple Instances”. Your code is almost a textbook example for what not to do with multiple ports. For your application I think you’d roughly want to do something like:

void loop()
{
  port1.listen();
  // wait for several seconds or until you get a valid code on port 1
  ...
  port2.listen();
  // wait for several seconds or until you get a valid code on port 2
  //
}

It’s hard to guess. Can we see your code?

I'm working with an Arduino Uno on which i'm trying to hook up two RFID readers (Parallax readers running at 2400 bps). (I'm running Arduino 1.0) I can get i to work fine with 1 RFID reader, but when hooking the other one up, it won't read anything. I pasted my code on pastie.org here: http://pastie.org/3890243 (Sorry for the danish comments a few places) It's meant to act like this: Reader1 reads the tag and lights a LED and if reader2 reads the tag and lights another LED and turns the other one off. CHeers for any help. :) /Marc Hey.

It print or transmit data correctly for some time means for just 5 or 10 seconds after that it transmit constant form of data.........i need your help Hi,

What is the processor clock speed on that device? Does the ATTiny85 even support pin change interrupts?

What is the processor clock speed on that device?

It's not just limited to the ATmega328. @Prakash,

I think NSS should work fine with Sanguino–as long as you have the correct timings. It’s not just limited to the ATmega328.

That's what I designed end() for. Let us know if it works...! @Nimit,

I use pb2 for rx and pb3 for tx. i tried 1, 8 and 20 mhz, at 9600 to 2400 bps without succeful. i see a lot of discussion over different forums but no easy end solution appears. Someones talk about hand tunning the clock processor. Do you have any tip to allow AtTiny85 support SoftwareSerial? Best regards Pescadito. hi

An improvement to old Arduino versions (up to 22) have been done by two persons Zac Hoeken for 644 and R K Sharma for 1284. Can I add your soft serial library to those Arduino 21 or 22 version or is it good for ATmega328? Regards, -P W Dandekar Hello,
