I connect my WP76xx module to external MCU via I2C. I want to setup such that when MCU send data to the WP76xx via I2C, it triggers interrupt and then call a callback in user space to implement the handling.
How can I achieve this?
Thanks @jyijyi , too bad then. It seems I2C is not a feasible choice to connect mango to other controller then. Probably UART would be better as both side can initiate communication as opposed to master slave constraint in I2C.
