The serializer is a great product and i love it. There are some features that i think would make the serilizer even better:
Odometry Support: Odometry is a very fundamental technique in robotics. And it would be really helpful if the second channel of the quadrature encoder is also reported to computer for odometry. Maybe a firmware upgrade could help.

| You are aware of the built-in PID motor control functionality, no? This allows you to control the exact distance and speed of the motors, using the dual quadrature encoder inputs. Best Regards,

1) thank you for responding Mr. Summerour. I really appreciate it :-) I understand that the serializer has its own PID's for navigation. And its a very useful feature as it takes away the burden from the user to worry about such stuff.
2) However, as you are aware that the true essence of PID comes from its tuning. This is what i want to achieve using lab view. but unless i get the second signal or an interrupt regarding the direction of the motors, i cant tune the PID's.
3) I also want to make a wall following robot that keeps keeps track of its location using the encoders. but for that i would need the serializer to tell me that the direction of the wheels has changed. this should be easy to implement using interrupts.
4) Although i have coded and manually tuned PID's on my other robots, i have learnt from experience that it is very possible to have the PID constants as floating point numbers. which the serializer does not support. Ringo had also mentioned earlier in the forums about adding floating point support. i also think it will be a good idea to consider.
