I know this is a little old, but I'm having the same problem. Did anyone get this to work with a VD230? Like Rx7Man I've tried several libraries.
Downloading the VD230 spec and testing the logic, it appears to differ markedly from the spec. For example, if the D pin is ground the R pin floats. That is also not in the spec.
I got the transceiver from Amazon. An interesting thing is the labelling on the VD230 wears off. If they were really from TI, I don't think it would do that. I've ordered a different transceiver but it will take several weeks to arrive.
