decoding quadrature encoders

[Luciano]

Hi,

I'm not sure I understand your problem.

Set the variable enc_counter to 30000.

If the encoder does one step you will
have either 29999 or 30001 in enc_counter. (CCW or CW).

The interrupt assembly code only decrements or increments
the 16 bit value stored in the variable enc_counter.

Is up to your PicBasic code in the main program loop to do
something with the value stored in the variable enc_counter.

Best regards,

Luciano
