I am using PCA 8574 I/O expander along with linkit 7688 module. I have both input and output ports in this I/O expander(P0 to P3 as input, P4 as output).
How can I configure this using mraa library?
How can I write value to this output port only?
Also I need to configure interrupt for these inputs using I2C interrupt which is connected to Linkit 7688.
