Has anyone successfully used Profibus with an AVR (in asm or C or anything else)
At full Profibus speed 12Mb
Using a VPC3 or a SPC3 interface chip, a TI transeiver and an ATMEGArunning at 12Mhz (SPC and VPC run at 48MHz, so devide by 4 and get 12Mhz)
I am interested in the success rate of this, and if anyone is willing to share code.
especialy the new VPC3 S spi serial interfaced chip.
12Mb comunications, and Profisafe would be good.[/b]
