Dear John:
I am probably not the right person to answer your question. I know nothingabout classes and objects and data structures.
I just wanted to see what the brain is doing and how to train it. I did not care if I did that the "best" or most "elegant" way or not. I used whattools I had access to.
Back in the dark ages when I began this project, 112,500 Baud rates were possible, but other factors made 9600 Baud the "practical" choice. I followed the HAL-4 format which is one sync byte and 4 data bytes. If you look onmy web site you will find the source code for the HC11 that acquired the data and sent it to the PC at 9600 Baud. I can see no reason to send data from the PC to the HC11 although that can be done and I believe the Brain Master does that.
This group can spend months discussing the "perfect" protocol, but here isone that "works". There is several megabytes of "real" brain wave data available for you to look at and write some code.
Why don't you "start" with something simple and write a small test program to look at the code? Logfile1 contains some test tones with which you can test your program.

Just a (hopefully) Quick Question!
What instructions can you give your hardware device
eg Set sampling rate
AND if you know what is the actual data sent over the RS232
eg MAYBE 02 03 04 :-)
Basically I need to know how the interface works between the hardware and
the PC?
Thanks for your help!!!
