NXP PCA9530 & NI USB 8451 Examples?

[Dhubbell]

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!

Thanks Dylanc!  After 14 years still nice to see some addtional suggestions!
