No Data out of accelerometer, magnetometer, gyroscope #336

Closed OgLocGreen closed 5 years ago

OgLocGreen commented 5 years ago

My Question is why do i have to Read more Senors on the Ti-CC2650 board to get the right data for the accelerometer, magnetometer, gyroscope. If i only read Accelormeter i wont get any data. If got two Sensor to Test with. Below is my Code and Output i get. Im happy if someone has some suggestion for improvements. Greetings Green

My Code:

import time
import datetime
import sensortag

#Sensor1 Init
tag = sensortag.SensorTag("CC:78:AB:7F:88:03")
sensors = [tag.accelerometer,tag.magnetometer,tag.gyroscope]
[s.enable() for s in sensors ]

#Sensor2 Init
tag2 = sensortag.SensorTag("B0:91:22:F6:84:84")
sensors2 = [tag2.humidity,tag2.IRtemperature,tag2.accelerometer,tag2.magnetometer,tag2.gyroscope]
[s.enable() for s in sensors2 ]

while True:
    timestamp = time.time()
    timestring = datetime.datetime.fromtimestamp(timestamp).strftime('%Y-%m-%d %H:%M:%S')

    #Sensor1
    [ s.enable() for s in sensors ]
    accel, magnet,gyro = [ s.read() for s in sensors]
    time.sleep(1.1)
    accel,magnet,gyro = [ s.read() for s in sensors ]
    [ s.disable() for s in sensors ]
    #print timestring, "accel",accel,"magnet",magnet,"gyro",gyro

    #Sensor2
    [ s.enable() for s in sensors2 ]
    hum2,IRtemp2, accel2, magnet2,gyro2 = [ s.read() for s in sensors2]
    time.sleep(1.1)
    hum2,IRtemp2, accel2,magnet2,gyro2 = [ s.read() for s in sensors2 ]
    [ s.disable() for s in sensors2 ]
    #print timestring, "accel2",accel,"magnet2",magnet,"gyro2",gyro

    #Printing Sensordata
    print timestring, "accel",accel,"magnet",magnet,"gyro",gyro
    print timestring, "accel2",accel2,"magnet2",magnet2,"gyro2",gyro2

    date = datetime.datetime.now()
tag.disconnect()

My Output:

thanks for the time.

I'd start with cleaning up the code. You don't use data variable and you do strange things with enabling sensors twice? Then you read them twice with a short break between - why? If you ask for help try to provide minimum working (or not working code) - remove your commented out debug prints and so on. Do you need to enable/disable sensors all the time? It's a genuine question - I'm not familiar with that hardware. Also you doesn't seem to disconnect tag2? P.S. A good idea is to use code checker (flake8, pylint)
