I wrote a simple evdev program to read from a Nintendo Switch JoyCon and print out any buttons pressed.
from evdev import InputDevice, categorize, ecodes, KeyEvent
device = InputDevice("/dev/input/event17")
for event in device.read_loop():
if event.type == ecodes.EV_KEY:
keyevent = categorize(event)
if keyevent.keystate == KeyEvent.key_down:
print(keyevent.keycode)
And when I run the program it has an output like this
['BTN_A', 'BTN_GAMEPAD', 'BTN_SOUTH']
BTN_C
['BTN_NORTH', 'BTN_X']
['BTN_B', 'BTN_EAST']
BTN_THUMBR
BTN_TR2
BTN_Z
['BTN_WEST', 'BTN_Y']
BTN_START
BTN_MODE
But when I pressed the ZR button this happens
Traceback (most recent call last):
File "test/button_lister.py", line 7, in <module>
