I'm trying to use a generic I2C sensor with my EV3, specifically, a Nintendo Wii Motion Plus (https://en.wikipedia.org/wiki/Wii_MotionPlus) I used this sensor with my NXT a couple of years ago, so I think my hardware interface should be OK.
What is the best way to do 'raw' i2c writes and reads?
I tried using the Sensor class, but it can't seem to find my sensor.
Code:
#!/usr/bin/env python3
from ev3dev2.sensor import Sensor
def main():
wmp = Sensor('ev3-ports:in4:i2c83') #I2C address is 0xA6, unshifted is 0x53 = decimal 83
wmp.command(0xFE, 0x04)
if __name__ == '__main__':
main()
Output:
Starting: brickrun --directory="/home/robot/vscode-hello-python-master" "/home/robot/vscode-hello-python-master/wmp.py"
