Hello All,
  Does anybody have any sample code using LPCOpen v2 with RS485 multi-drop using the address?  I've gotten this to work with CMSIS but I can't seem to get my head around trying to do this on LPCOpen.

I'm using LPC1115 (acutally LPCXpresso board for testing).  Also using LPCXpresso v7.3.0

Any help would be appreciated.

Thanks in advance.

I'm also interested if there are plans to release something like what I see with LPCopen 1.03... 

I'm just starting to look at what it will take to manage the 'detect end of last byte transmission' in order to de-assert the rs485 tx_enable...   I'm presently polling the transmit ring buffer empty condition and then waiting for a timed delay for the byte to transfer - not the best way, but it's a start.
