Hi Naveen,

What specifically do you need when you say "software device driver?"

Hi Naveen,

We do not have a linux device driver for this device TCA6424A.

There is some linux source code for PCA953x: https://git.ti.com/cgit/keystone-linux/linux/tree/drivers/gpio/pca953x.c?id=d1c057e31734426ba385e02291d97bdf06ba0c1d

You might be able to reference this material when looking at the TCA6424A. The registers writes and reads should be the same. The addresses will change because TCA6424A is a 24-bit device as opposed to a 16-bit or 8-bit IO expander.

Regards,

Tyler
