Probing Sensor Data with Oscilloscope [Groupwork]
For our groupwork this week, we decided to probe the Quadrature Encoders.
Probing Quadrature Encoders
Quadrature encoders are perfect sensors to probe with an oscilloscope.
- They require 2 channels, which will give us a nice demo to watch.
- They are timer dependent, channel 1 leading will mean it's going in one direction while channel 2 leading will mean it's going on the other direction.
Connection:
- Board ----------------Oscilloscope
- GND ----------------- GND probe for both channel 1 and channel 2
- CLK ----------------- Channel 1 positive probe
- DT ----------------- Channel 2 positive probe
Then we pressed 'autoset' on the scope to give us the following video
