Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I have a small program autorun.bas (below) to clear my I2C units.
I have OPTION AUTORUN ON

print "Reset I2C bus"
i2c open 100,1000
i2c write &h20,0,1,255
i2c write &h21,0,1,255
i2c close
print "Finished"

When I power up or hit RESET button, the response is :-

Reset I2C bus
Finished
print "Finished"'|7

If I just run the program on its own it's fine.
Where does the last line come from? What am I doing wrong?

Version = CMM2V5.05.05RC9.bin

Hi romba6,

as s first step I would update to the latest firmware update.
RC9 means "Release Candidate 9" the release version is CMM2V5.05.05.
I would this version test: https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=12998&LastEntry=Y#158101#158101.

For me - on the first glance - it looks like a minor old bug.
Without your I2C device I can't fully test your code.

I don't think it should be needed but it is a good idea to end your program with END

  Quote  PRINT "Finished"
END


It fixed the problem for me.

Thank you Jim - it fixed the problem for me too !!!
What threw me was the fact that the program works perfectly when run on its own but not in AUTORUN
