Encoder assistance needed

Here are a few lines from Kevins encoder readme.txt

Quote:

Five things must be done before this software will work
correctly on the FRC-RC:

1) The left encoder's phase-A output is wired to digital input
one and the phase-B output is wired to digital input six.

2) The right encoder's phase-A output is wired to digital input
two and the phase-B output is wired to digital input eight.
...

In other threads it says to wire the hall effect sensor (4 pins) to pwm (3 pins) with pins 3&4 together.

This nets one sensor and only one pwm connection.
1. Is this Phase A or Phase B?
2. Where do I find the other?
3. Or how is this physically wired.

Thanks,

Phil

The navigation code is meant to be run with an encoder, not the Hall Effect sensors.

Encoders will have Phase A and Phase B outputs, whereas your hall effect sensor will only have one output.

To use the Hall effect sensor instead, you will want to use only Phase-A, and then modify the Interrupt Handlers to not check the Phase B output, but to check the direction of the PWM output associated with that hall effect sensor.

Sorry if this is rather vague, but hopefully it will help.
