Open Drain Output pic24F
PostPosted: Tue Dec 29, 2009 3:53 am     Reply with quote
I need to use on PIC24F an output as ano open drain.

I just need to set to 1 the propper bit of the ODCx register.
Is there in CCS a function or a pre processor directive that makes this?

thanks

No.
- You can define the OCD registers yourself by #byte or #word statements
- You can emulate open drain by switching the respective pin between output_low and input, as it would be
done with other PICs that don't have OCD registers.
