I am making a weird robot out of k'nex and a pi and I am controlling it over bluetooth with a DS4.
The DS4's D-pad will control the movement. I was looking for librarys to drive the controller, and I found approxeng.input. Judging by the docs, seemed a relatively good library, and, as I have a WiiMote too as a backup, I was hopeful. I tried to install it with:
pip3 install approxeng.input
here it the output:

After a bit of trial and error, I found I could do this:
pip3 install approxeng.input==2.6.2
but whenever I tried pip3 install approxeng.input==2.6.3(i.e the newest version, according to the docs) the long list of errors came again.
So i went along with working with the older version, and I made a fair script to make it go forwards and backwards:
from approxeng.input.selectbinder import ControllerResource, ControllerRequirement, ControllerNotFoundError
from approxeng.input.dualshock4 import DualShock4
from gpiozero.pins.pigpio import PiGPIOFactory
from approxeng.input.controllers import ControllerNotFoundError
from gpiozero import Device, Servo
from os import system as cli
Device.pin_factory = PiGPIOFactory()
s = Servo(2)
# Get a joystick
while True:
try:
with ControllerResource(ControllerRequirement(require_class=DualShock4)) as joystick:
print(str(joystick.battery_level * 100), '%')
# Loop until we're disconnected
while joystick.connected:
joystick.check_presses()
if joystick.presses.dup:
s.min()
joystick.set_ds4_led('green')
while not joystick.releases.dup:
joystick.check_presses()
s.mid()
joystick.set_ds4_led('blue')
if joystick.presses.ddown:
s.max()
joystick.set_ds4_led('red')
while not joystick.releases.ddown:
joystick.check_presses()
s.mid()
joystick.set_ds4_led('blue')
except ControllerNotFoundError:
print('Waiting to connect.)
Then I checked the docs for the information on release 2.6.3. It seemed they had added support for controller vibration, which I thought was cool, so I kinda wanted that new version, but I didn't know how to get rid of that error. Any help appreciated!
