Hello,
I have 2 launchpads. One of them is TX and the ohter one is RX device. TX device have 4 buttons. 2 of them are BTN-1 and BTN-2 and new buttons are Board_DIO12 and Board_DIO15.
If buttons are not pressed, TX device should be in shutdown mode to save battery. So, I mixtured Easlink RF example and pinShutdown example.
The problem is board behaves as if NEW_BUTTON3 always pressed. How can I eliminate "always button pressed" problem ?
Here is the code:
