Other Parts Discussed in Thread: FUSION-DIGITAL-POWER-STUDIO

Hi team,

Below is a question from my customer JND technology:

They would like to implement a second development of the software that expanded the I2C read feature shown below, but they don't know which function interface in TIDP should be called to use this feature. There is no example of this feature in the official documentation for TIDP.SAA.

Could you help to support on how to use I2C Read Extended with TIDP.SAA?

Thanks,

Frank

Hi, Frank,

UCD9XXX does not support I2C extended commands. From your screenshot, look like you are using "Fusion Digital Power Studio" (https://www.ti.com/tool/FUSION-DIGITAL-POWER-STUDIO) which is belong to HVC.

We close the thread here. Please reopen the FUSION_USB_ADAPTER_API: How to do I2C Read Extended with TIDP.SAA interface ticket, and mention Fusion-Digital-Power-Studio as product.
