RE: [Sumo11users] Re: Error Messages when downloading
I am
sure your programming is beyond reproach, everyone’s is. but would you mind sharing your actual logic for the RPM
calculation with the encoders? I really suspect that is the issue. Also, you
should confirm that the physical encoders are working correctly. That is mount them on an axel and verify that one revolution always
produces the correct number of ticks for the resolution of the devices…

Thanks Dan, I appreciate your help. Please let me know
if you run accross a fix for the encoder problem. It is hindering with my
control system, I hope there is fix for it.

Hi,
Sorry for the delayed response. Please note that the error message
has absolutly no ill effect on Sumo11 functionality and can simply be
ignored. However it is annoying and can be fixed fairly easyily by
overwriting the lib_sumo11.frm file with the one found in the files
section of this groups message brd.
There was a mixup in communication with the last release of IC, I was
told that the new version would be defined as IC 5.0 and built the
Sumo11 firmware under that assumtion. I sent my files in to be
compiled with the new release of IC and found out later that the
revision did not go to IC 5.0 but 4.301 instead. Anyway, it was
Botball season and the developers of IC did not want to make any
changes at that time, so the Sumo11 gets the error.
As for the encoder issue, I'll have to look into that some more. I do
seem to remember a similar issue I had with the Handyboard, but it was
something to do with the way I set up the encoders in my code. More on
this later.
