TCA9548A: May we know where can get control TCA9548APW & TCA9555 sample code?

Hey Chen,

We typically do not provide code for our devices. One thing you can do is search on google for some code/drivers. To make the search easier you can search for PCA9548 and PCA9555 as the NXP drivers/code should work for our device as well.

Now, I recently got into coding in Arduino which is C++ based so I may be able to show an example with commenting for you.

Note: I am using a library called Wire to call functions.

Initializing values:

Example code:

I hope this helps.

Thanks,
