Hello! Can any one please help me to explain how i could read data from my sampler in the C-code, I have tried to use the parallel.device but it will just hang when i do the read command. When i use other programs for sampling they work fine, maybe they read directly from the hardware port. I will appreciate any help. Thanks in advance ! Lars Berntzon mcsun!sunic!spader!lab

You are right in that the reguler parallel device does not work when
trying to talk to a device other then a printer. The normal parallel.device
want to receive paerout, and other standared printer port signals. The only
way to acces the port directly is to talk to the CIA ( complex interface
adapter chips ) whic the amiga uses. I have had no succes myself yet in
talking to these chips. However you might have better luck. You will need
the ROM-KERNEL manual which has a brief chunk of code in assembly that is
supposed to acces the cia chips. Also there is some source code on a fred
fish disk ( I dont remeber whic number) that contains the assebmly source to
acces the chips. However when I use the assebler that comes with lattice-c to
assemble the code it dose not work.
