Is it possible to use the Software Serial Library with 3 devices on an Arduino Uno?
(This excludes the Hardware Serial port on D0+D1)
The parts for the project will arrive in the next two weeks but I thought I'd just ask the question. The project involves having 3 RS485 connections.
I know the library has some limitations like receiving and transmitting at the same time. This is not an issue as the Arduino Running the 3 Software Serials will act as an Master sending 1 request at a time and then waiting for a reply.
Just did a search and another option is to use a SPI/I2C to UART converter if the above is not doable. http://www.digikey.com/product-detail/en/SC16IS752IPW,112/568-4016-5-ND/1158199
Any help would be appreciated... Thanks.
