Power PC 555 -- tpu

Started by Mark Brehob November 20, 2008
Hello,
We are searching high and low for a set of header files (and C files?)
for the powerpc 555.  tpu_pta.h is what we know we need.  I think
there is also an associated C file (tpu_pta.c) but I'm not certain we
need it.

Anyone have a clue?  Web searches are turning up very little.

Briefly, I've got a group of students trying to use the timers to
figure out how long a signal is high for (ultrasonic sensor among
other things).  I suspect they can just manipulate things by hand, but
having the suggested headers/functions seems like the right way to go.

Thanks,
Mark

You should be able to download these from the Freescale website. They also have an online application to generate header and C files for user-specified selections of TPU functions (at least, they do for the MCF523x eTPU).

Yep. We got a reply. That there was basically nothing on the web scared us, but Freescale was very fast in getting back to us. Sorry to waste folks time. Reply follows: =3D=3D=3D=3D=3D The tpu_pta.h file can be found in the software files archive for the AN2365: http://www.freescale.com/webapp/sps/download/license.jsp?colCode=3DAN2365SW= &location=3Dnull&fpsp=3D1 All the software files for the appnotes are available from the web site by clicking on the zip icon to the right of the appnote link.
