}You need cython-hidapi to use Bluetooth / HID connection in Python.
Alternatively, you can use hid instead if cython-hidapi fails to find your JoyCons.
Gyroscope
We have a specialized class which tracks the gyroscope for you, and exposes this tracked state in a simplified manner:
from pyjoycon import GyroTrackingJoyCon, get_R_id
import time
joycon_id = get_R_id()
joycon = GyroTrackingJoyCon(*joycon_id)
for i in range(20):
print("joycon pointer: ", joycon.pointer)
print("joycon rotation: ", joycon.rotation)
print("joycon direction:", joycon.direction)
print()
time.sleep(0.05)Button events
We have a specialized class which tracks the state of the JoyCon buttons and
provides changes as events. Here is an example of how it could be used with pygame:
from pyjoycon import ButtonEventJoyCon, get_R_id
import pygame
joycon_id = get_R_id()
joycon = ButtonEventJoyCon(*joycon_id)
...
while 1:
pygame.time.wait(int(1000/60))
...
for event_type, status in joycon.events():
print(event_type, status)
...
pygame.display.flip()Combining multiple JoyCon helper classes
