Hello,
I'm working on a drive control with a F28377.
Currently, our drive can be driven from CAN or EtherCAT bus with Cia402 profile.
The architecture is to have an external Chip (ET1100 for EtherCat) and with the SPI, get message and in the F28377 implement all communication stack and Cia402 profile.
We want implement the Profinet bus with its profil (Class1 to 6)
We found some external chip (Hms, Hilsher..) which is a real external µC with a basic soft integrated and other part (application part) in our F28377.
But like the F28377 Char work on 16bits, this is not easy to integrate an external stack designed for 8bits!...I did it for the EtherCat stack provided by Beckoff...
Is Texas has a solution to implement easily the Profinet Bus with its profile (Code exemple...)? The idea is to have an external chip ( abour $10) linked on SPI to communicate with the F28377.
Then the data exchanged on this SPI are not important, it can be low layer, or high layer application according the work done by external chip...
Thank for your help
