ADSP 21161N ez_kite_lite, english

Started by chris_08 April 22, 2005
Hello!

I am a student of the TGM a technical college in Vienna.

I use the ADSP 21161N_ez_kite_lite board with a SHARC processor. I
need help because I want to receive some signals (HIGH/LOW) from an
external board which is connected to a port from the DSP. The signals
will be used by the application.

I have problems to address each bus-line from the port separate. I
tried this by the external port 9 which I prefer, but with no success.
An interrupt-routine should receive the signals. The timer and his
interrupt are programmed successfully by me.

I need this for my project which I need to get my graduation
certificate from high school.

Please help me!

Regards

Christian

I don't understand exactly what you're trying to do, but it sounds like you should be using flag pins instead of the external port. Have you read the Hardware Reference Manual? http://www.analog.com/processors/epManualsDisplay/0,2795,,00.html?SectionWeblawId=433&ContentID=58316&Language=English Watch for word wrap in that link. The external port is covered in chapter 7. The flag pins are in chapter 13. -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas@bittware.com http://www.bittware.com (603) 226-0404 x536 Things could be a lot better around here, but worse is more likely - Calvin
