current reference lookup for encoder

made a file that converts the reference for hall effects to a reference for the encoder

I had difficulty when I tried to run that as there was apparently not enough room in DRAMH0

I increased the size of DRAMH0 in the cmd file in ccs and then rebuilt the project. This time the project built but the motor did not work.

I then tried with an internal memory map for the cmd file in the ezdsp setup in the model.

This time it I get the same error

here is the cmd file that i am using

/* [EOF] afm_060530a.cmd */

which now that i look at it is the same memory mapping as the custom one that I was using.


Try the modified one that is based on jess' (afm_060530.cmd)

same error

this is what that cmd memory map looks like

that has an even smaller DRAMHO
