### Button Test ### Button Test
[button_test.py](button_test.py) [button_test.py](button_test.py)
This example shows you a simple, non-interrupt way of reading Inky Frame's buttons with a loop that checks to see if buttons are pressed. Inky Frame's buttons (and the RTC alarm, busy signal from the screen and external trigger from the hack header) are connected to a shift register to help conserve pins, and to allow these inputs to wake the board up from sleep.
This example demonstrates a simple way of reading when a button has been pushed by reading the shift register and checking if the bit in a specific position is 0 or 1.
