I have a device I need to test that uses I2C bus.

The device is a board with a microprocesssor on it that is an I2C master

Can the USB-8451 be an I2C slave?

Hi RTSLVU-

Unfortunately, the USB-8451 cannot currently function as a slave on the I2C or SPI bus. Please consider visiting the Product Suggestion Center and submitting this feature as a product request. The more suggestions that are made, the more likely is that this functionality will be implemented in a future version of the hardware.

Best Regards,

Thanks, I submitted a suggestion.

Now I understand why this USB-8451 was sitting on a shelf collecting dust.

We decided to go with this device from MCC because slave mode is required to test our product.

Hello,

I'd like to know if there any updates regarding functionality of the NI USB-8541 as a I2C slave ?

Thank you

Unfortunately, there haven't been any updates for using this device as an I2C slave.

Any news about this? Is it a hardware related limitation or only a software issue that the USB-8451 cannot be a slave? We also need a slave device to test our battery chargers in our products.
