Part Number: TCAL9538
Other Parts Discussed in Thread: PCA9538, TCA9538

The customer is using TCAL9538.

They want to know whether we have sample code for their reference?

    Hi Fabio,

    We do not supply sample code for our devices. 

    Operating the TCAL9538 IO expander however is similar to that of code for the PCA9538, TCA9538, and TCAL9538. If there is a resource library online with code written for the other two devices (PCA or TCA version), that sample code would work generally for the TCAL9538. There would need to be some changes to the coding of course, since TCAL offers a wider register map, and more in depth configuration for the p-port pins. 

    We might attempt to generate professional code for these devices in the future, but right now there is not enough time to portion out to developing software to use for these devices. 

    Regards,

    Tyler
