TCA9554A: Linux Driver

Part Number: TCA9554A
Other Parts Discussed in Thread: TCA9554, PCA9554, PCA9554A,

Is there Linux Driver of the TCA9554 for customer development tools (AM3352xx)? Thanks.

  • Hey Brian,

    TI typically does not provide drivers (code) for our devices, we do provide support from an analog perspective and can help in terms of how to set up our device from a register stand point.

    For drivers, I found on google two 'github' sources which seem to have drivers.

    Our device is pin to pin compatible with our competitor whose device name is PCA9554A so any code which works for PCA9554A should work for TCA9554A. Also an extra bit of info, you can use the PCA9554 (non-A) drivers you find online as long as you fix the static address for the drivers. The only difference between our TCA9554A and TCA9554 is the static address so everything else in the driver code should still function correctly.
