Orangutan_B

Support A-Star and Orangutan

Hi!

I was wondering if the Orangutan_B is setup to accept dual quadrature encoders.

Since it can drive two DC brushed motors, i would assume so… but after some digging, only one internal interrupt pin is available (PD2 = INT0), and PD3 (INT1) is tied up on the M2 control line. Since these seem to be the only internal interrupts for the ATMEGA328P, i’m wondering what the deal is for dual encoders…

Please advise.

Hello.

I moved your post to our “A-Star and Orangutan” subforum, which seemed more appropriate.

Yes, it is possible to measure the outputs of two quadrature encoders on the Baby Orangutan. You can find more details in the “Pololu Wheel Encoder Functions” section of the Pololu AVR C/C++ Library User’s Guide.
