Where can I find this pdf file? I'm having the same problem. I'm sure its in my not setting the buffer chip direction but I can't find the power pmac address for it (acc5e manual only addresses turbo) It was incredibly difficult for me to find the post with the desired attachments again: http://forums.deltatau.com/showthread.php?tid=408&pid=3346&highlight=multiplexed+thumbwheel#pid3346 The search terms that finally found it were "multiplexed" and "thumbwheel".

The answer was found in Sina's pdf and associated code "Using ACC-5E I/O through Power PMAC" The only other thing I had to do to configure the gpio ports for output was to set the buffer control bit for the appropriate byte.

I can't seem to configure any of the JIO GPIO bits for output. Acc5E[0].LowIoMode=$ffffff; Acc5E[0].LowIoDir=$ff; Setting Acc5E[0].LowIoData does not change the state of any of the JIO bits. They remain input bits. What am I not doing right?
