#186198 - I implemented RTU but.. Responding to: ???'s previous message |
Hi Bill
RTU or ASCII can be implemented with little difficult in almost any 8051 derivative (provide it has at least one serial port). You need the specs of the link master-slave. ASCII is easy to implement. RTU requires CRC calculation, but in http://www.modbus.org there is a document with a nice C function in the last pages. To implement it in Assembler is simple. Start doing something according to your needs, and people here will be glad of helping in your specific difficulties. Daniel |
