Other Parts Discussed in Thread: PCA9534

Hello,

I am trying to access the GPIOs on the I2C Expander chip PCA9534 . The driver for the same is available in the Linux kernel. My question is: how do I access  (Get,Set,Configure the IO as input/output) the GPIO on the I2C Expander from user space application.

Thanks,

Tomy
