Hi, Anyone knows where I can find the source code for PROFIBUS protocol, I want to implement it in a 8051. Thank you, Adi,
Profibus protocol can reach speeds up to 12Mbit/s, which cannot be obtained using the 8051 asynchronous serial interface. We normally implement Profibus DP slaves using the Siemens SPC3 chip or the VPC3 from Profichip; Profibus Master ASIC is available only via Siemens. On this site you can obtain all the informations regarding VPC3 (SPC3 is exactly the same) http://www.profichip.com ciao Bruno P.S. As far as I know, nobody implements the Profibus protocol into a microcontroller, everybody use the ASICs. Maybe you are speaking about the Siemens MPI protocol, which is a low speed Profibus like protocol, but no documentation exist about it and it can be implemented only via reverse engineering of the MPI dialog between a Simatic PLC and an MPI peripheral.
Thank you for the HELP, I will take a look at the product.
