PUB does notload to COG

nicolad76

Hi,
I have been using COGS forever but always loading PASM.
Today I do not really need PASM (lucky day!!!) so all my routines are in SPIN.
I checked the manual on how to execute SPIN to a cog but I could not get it to work.
What am I doing wrong?
The original file is in attachment.

Pub Main | cN , ok

Setup(11,10,10,21,20,0)

ok := (cN:=CogNew(PPark(bStopDir0,bStopDir1,bDirection,bParkDirection,bStep,lStepPerUnit),@stack))>0



Nothing happens when I use the above code. If I call the PUB
PPark(bStopDir0,bStopDir1,bDirection,bParkDirection,bStep,lStepPerUnit)
Then it get executed. This prove that the PUB itself shold not be an issue.

Thanks!!!!

Don't forget that each cog has its own special function registers, including DIRA. You can't set DIRA in one cog and have OUTA in another cog produce a pin change.

PPark is executing. It's just not doing what you expect.

Each cog has its own copy of the DIRA and OUTA registers. When you execute Setup, that sets up the DIRA register in the main cog. When PPark executes, it's using a different DIRA register that's initialized to zero. You have to move the code from Setup into the beginning of PPark so the proper DIRA register gets initialized.
