I2C Stability - Production Quality Hardware

[RDalton]

Hello NI Land,

Fairly fresh to these forums so take my ignorance in stride. I have a production related issue going on with an I2C bus and more specifically the hardware. We have a proprietary control that our company designed and we program some settings using an I2C bus that we have integrated on the product. Right now we are using a totalphase I2C tool to communicate from the PC and our product. We have kept all of the USB cables and junctions very short so the loss is minimized. I believe our code is very solid and communicating the way it should, but we are constantly having issues where it will not program and we reset the totalphase device and it begins to work again. I was wondering if anyone out there has any recommendations on solid hardware to use. The totalphase product was fine for development but I believe it lacks the stability needed for a production environment. 

Thanks

Ryan

I've used this card from NI at a previous employer and had no issues. It is rather pricey for I2C but definitely stable.
