Multidrop RS485


#1

Hi,
I am about to buy the dev kit for an upcoming project. I was wondering if the serial library would allow for multidrop ( 9th bit set, stick parity?) and 485 direction switching.
Thanx

Not directly but see this http://code.tinyclr.com/project/280/rs-485-driver-using-rlp/

Thanx, this will help. Which CPU is currently used on the Chipworkx?

OK, I checked the datasheet and the uart on that is pretty clever. All you need for RS485 is to set a register bit and its done automatically. There is also a specific register to send an address byte with 9th bit set. ;D
