Hi Forum, I have tried to get this tutorial to work: http://arduino.cc/en/Hacking/LibraryTutorial, but without any luck so far. The program is exactly the same as in the tutorial. I have an Arduino UNO.
I have bought the ICL232 because I could not find the MAX3323 in my country. So first question, can the ICL232 be used instead of the the MAX3323? Renesas Electronics Corporation
First I did a loopback test with the Serial cable and tested it using Realterm, and there were no problems. Then I connected the wires in the folowing way:
Arduino pin 6 to pin 12 of ICL232.
Arduino pin 7 to pin 11 of ICL232.
Serial cable pin 2 to pin 14 of ICL232.
Serial cable pin 3 to pin 13 of ICL232.
Serial cable 1,4,6 connected together
Serial cable 7,8 connected together
Serial cable 5 to ground
The capacitors is put in place as well
In Realterm i get output, but the ASCII characters is mostsly above 128 and is mostsly nonprintable. One thing that makes it difficult to debug is that the printed ASCII characters change. Some times it prints one character, and sometimes another. I therefore tried altering the baud rate, but sofar without luck.
The cable is a profilic cable. Realterm is set to no parity, 1 stop bit, no hardware flow control
Any suggestions will be highly appreciated!
