In TCA8418 an interrupt (/INT) output can be configured to alert key presses and releases.
Can anyone guide me on how to generate interrupt by pressing a key present on my AM1808 evm.
The datasheet says- the user first checks the INT_STAT register to see if there are any interrupts. How to do this ????I have tried accessing the INT_STAT register using i2c_smbus_read_byte_data(file, INT_STAT) and i2c_smbus_write_byte_data(file, INT_STAT, value_INT) function but in vain.
I have been trying this for a while and have had no luck whatsoever. Please get me out of this ...
how to clear Interrupt state in TCA8418?thanks
