How to convert I2C Master to SMBus master?

[MikrobiUK]

I work with myRIO for implelementing of SMBust protocol. After few trials I decide to convert existing I2C master solution for myRIO - look good, separated code consumes 65% total slices in compilation.

(bat the way: why so much?)

Did any of you made implementation of SMBus at myRIO ? any tips? How can I reduce amount of consumed slices ?

Good Morning MikrobiUK,

Officially, we can only communicate with myRIO by two ways: I2C and SPI and there is an API developed for you to use both protocol as shown below:

“SPI and I2C Driver API - National Instruments” 

Hence we don’t recommend you to use the SMBus protocol.

Please let me know if you have any other thought.

Thank you.

Well that is my starting point, I need to spent more time with that. Also I2C implementation dedicated to myRIO looks fine.

And  yes, I would like to use proper I2C protocol, but I have hardware that operate with SMBus protocol and I need to communicate with that.

I will continue my work with that..
