Hi ,
I wonder for reading quadrature encoder, what is the main advantage of using eQEP module over simply using external interrupt? does eQEP use separate hardware counter and timer interrupt process so it won't disturb the critical controller interrupt?
By my sense, I find it a lot easier to program the external interrupt to read quadrature encoder without any need to understand the register and process behind eQEP module
another point is, I use TMS320F28027 for all my current application, including now motor control. Will it be any different to use external interrupt to read the quadrature encoder compared to eQEP since this uC doesn't have eQEP.
Thanks,
