Does anyone have example Labview code addressing the NXP PCA9530 (2-bit I2C-bus LED dimmer) through the NI-USB-8451?

Thanks!

Hi Dhubbell,
I could not find any examples specifically for the NXP PCA9530 but here is a great white paper on using the 8451 with I2C communication.

There are also LabVIEW examples you can find using Example Finder after you install the NI-845X drivers found here:

Thanks DylanC. I found my problem, the white paper on the Chip was referencing a 8 bit address and I was using a 7 bit address in my code. It's working fine now. I used a good old fashion "loop" to find the correct address!
