Read-Only Author Adi Sapner Posted 21-Sep-2004 16:28 GMT Toolset C51	PROFIBUS and 8051 Adi Sapner Hi, Anyone knows where I can find the source code for PROFIBUS protocol, I want to implement it in a 8051. Thank you, Adi,
Read-Only Author Bruno Coppi Posted 21-Sep-2004 17:28 GMT Toolset C51	RE: PROFIBUS and 8051 Bruno Coppi 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.

Read-Only Author Amin Lalani Posted 23-Sep-2004 13:42 GMT Toolset C51	RE: Sir i require ur help Amin Lalani the LED is interfaced on the Kit with 8051 on its board normally for true or false answers that r responed by the program feeded in uc....now how is it done is a question which is normally asked in interview...

If he hasn't figured out how to connect an LED after 10 months I should think he will have given up and gone back to flipping burgers. We would all be grateful if you would please avoid posting to long dead threads as they clutter up the forum.
