PSoC on a RS485 bus

Postby Rick Morgal » Fri Jan 27, 2006 10:52 am

Does anybody know where I can get some information about using a PSOC 27xxx on a RS485 bus? Since the PSoC's UART parity generation is only odd, even or none I am wondering if there is an easy way to designate addresses versus data over the RS485 bus? Reducing the number of RS485 bus related interrupts each PSoC on the bus will have to resopnd too.

Hi Rick,
My advice is to search the forums. I know that the topic of a 9 bit UART for addressing purposes has come up before and I'm pretty sure there were relevant answers.

If you understand it,
then it's obsolete!

One of the topics where this has been discussed is Interrupt on 9th bit for UART?
Application Note AN2269 "Implement 9-Bit Protocol on the PSoC™ UART" is here.
