Microcontroller/Development board for reading Quadrature Encoder

[Navivanuva]

Hi all,

Im looking for a microcontroller/development board to read quadrature encoder(5000ppr).. I have tried using Arduino (Mega and Due) also TI Launchpad(MSP430 and Launchpad f28377s). I got the best result from launchpad f28377s.. Any suggestion?thanks

Btw, the launchpad f28377s is 200mhz and has 2 encoder inputs(called eQEP in TI)

Are you using the basic count/rev or using any edges to increase x2 or x4?

I am using x4 count mode

So 20kp/rev?

So 20kp/rev?

Yes.. I will alsocuse it for linear scale encoder.. 0.001mm resolution
