6221 and IDW

[senmeis]

Hello,

I would like to use I2C interface with a 6221. The requirement of the library "IDW" is that the device must support "per-cycle tri-stating" like 655x. Could somebody tell me what it means? How can I make some changes to my device to fulfill this requirement?

Thanks

Hi Senmeis,

Here is a link to a description of per-cycle tristate.

There is a white paper that does a detailed explaination: Serial Protocol Communication Reference Design for Digital Waveform Devices

I don't believe you will be able to use a non-655x device.

Best regards,
