Hi Sean,

We do not have Linux or Windows drivers available for this device.

Does the customer require linux or windows drivers?

They might be able to leverage the existing linux driver for the PCA9539.

I found this document online:

https://www.kernel.org/doc/Documentation/devicetree/bindings/gpio/gpio-pca953x.txt

The way that the registers are written to the PCA953x I/O expander is similar to how you would write to the TCA6507 however the registers for the 6507 are very different than the PCA953x. Let me know if this helps.

Regards,

Tyler

Hi Tyler,

Customer is asking why we don't offer driver for TCA6507RUER if it needs to be driven under Window/Linux?

Do you have a guide how to set up TCA6507RUER ?

Thanks a lot!

Hi Sean,

Driver support is something in progress across our product line.

The TCA6507 does not need to be driven under Window's or Linux only. The device only needs some type of I2C waveforms to operate. Windows and Linux can do this from an O.S. perspective, but any micro controller can operate the TCA6507.

Tyler
