Discussion Groups | Rabbit-Semi | Re: RCM4010 Serial C Ooutput
This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
Re: RCM4010 Serial C Ooutput - whmeade2008 - Mar 26 19:39:02 2008
I would like to thank everyone who responded to my question. Come to
find out, serial Port C and D on the RCM4010 DEV Board have been
reversed according to the Rabbit Technical Staff.
They even sent me a short sample program to use, but that didn't work
either. I have another email into them to see whats going on.
Thanks again for this groups support.
