Hi Karsten Krause

I am using an 80c320 running at 24 Mhz , PCF 8574 is used to scan
a 4*3 Key Bd: , I am a beginner but Looking at Peter Dannegers and
Ben Zijlstras code I've suceeded in developing the code to scan this key
Bd: . It is working ,but not running in a loop, means every time a key is
read I've to reset manually and reload the program once again then only
another key can be read. I am still struggling to fix my codes.If you
would like to see my code please e-mail me .I would be glad to send the
codes, may be you will be in a position to help me also. Bye ,Regards.
