hi all,
RS-485 is very low level embedded micro's network, but easy to implement with 9 bit Master-slave protocol, first implemented by our Father of Micros, Intel, as Bitbus in 70s.
CAN is robust protocol with its own hardware standard and automatic error detections, originated in 90s by BOSCH for in car communication, but needs upper level application support or firmware library such as CAN-Open or CAN-Kingdom for its full and efficient utilization.
Is any one has ready made source codes for above 485 and CAN to try with micros?
Thanks in advance,
Regards,
Yes, many has. But always more or less processor-specific.
