TinyIOx & Spartan2 OEM I2C questions

Postby jsiedlicki » Sun Sep 18, 2016 4:22 pm

Jean,

Purchased a TinyIOx to use with 2 Spartan2 OEM wide band controllers. I want to use I2C to communicate between them.

1. What is the default I2C address of the TinyIOx?

2. Do the Spartans need to be numbered sequentially and directly after the TinyIOx?

3. Do you know of any utility/software app to communicate with the Spartan2 boards via I2C so I can change their I2C address? (Alan does not provide anything).

Thanks,
John

John,

The Spartan2 OEM is not supported by the current TinyIOx code. The only module supported on the I2C bus is the SLC OEM (the Innovate LC1/LC2/MTX-L is supported on the serial port).

I'll have a look at what would be needed to support the Spartan2 OEM and I'll come back to you.

Thank you Jean, I was not aware it was not supported yet when I bought them. My bad... :oops:

Jean, have you had a chance to look at the Spartan2 OEM I2C specification sheet to see if can be supported?

Yes and the plan is to add support but I don't have an ETA yet. I also want to make sure to have support for changing the I2C address.

Jean, any chance of this happening by spring 2017? That's when I plan to fire up my new engine :)

I'm interested too using the i2c spartan2 oem with 4.9 lsu. Also, on the 14point7 website, they suggest for new designs to use the spartan module instead of the slc oem....

Support for the Spartan 2 OEM should be ready in the near future (a few weeks, maybe a couple of months). I also have a few boards in the pipeline to carry them and make it easy to use with the IOx and TIOx.
