Welcome!

In the component setup under advanced there is a box labeled "RS-485 configuration options"--- with a check box marked "Hardware TX-Enable"

   

I assume this is for the output pin to pull the enable on the 485 chip high for transmit. Is this correct? If so I cant get it to work and pull the output pin high.

   

Ive been just using the pin enable and disable functions in the interrupt to switch from transmit to receive.

   

I cant seem to find the code either that enables the pin. Does anyone have any idea of where it is in the API or is it a hardware function?

   

Thanks

This seems to be a project with pretty good documentation!

   

What do you think about sending it to Matt Landrum who was searching in his blog for themes for examples (He'll be back in the office on January 5th) as a request for an example project with a solution?

I don't think, Bob. It's just a picture found on the Internet.
I try to store such information in the projects so as not to overload your memory.
