We have a customer who is currently using our HV Sistemas H8606 board with a 16550-class UART programmed into the FPGA and a RS485 interface who is running an application for data acquisition and control of several distributed control modules using Modbus protocol. I think that he is using a public domain Modbus library, and as far as I know he had not found any problem in implementing the library and the application under uClinux. I will try to know which library he is currently using if you are interested.

 

Best regards,

 

Javier

I've asked my customer, and told me that he found that code here:

 

http://www.geocities.com/pbmcrae42/index2.html

http://www.geocities.com/pbmcrae42/linuxmbus.ZIP

 

He however has warned me that he had to modify the code because packet CRC calculation was not right and he had to do a slight modification of the code. I hope anyway that this can be of some help to you.

 

Best regards,

 

Javier
