Hello,
Can anybody help me out? What does exactly quadrature signal mean? how to generate a quadarture signal? you have a value in the counter which tells us about the postion of the encoder and then with this value i am supposed to create standard quadrature o/p (2 or 3 oututs, A B and RM) from PWM or outputcompare pins of a pic micro. The preferred frequency could be in the range of 1Mhz or more. The timing parameters for these outputs will be obtained to 2 Inputcapture modules in the microcontroller from the outside analogue world. Can we create this output at good resolution (around 1um resolution) when the linear change is around 1m/s? Is it possible to generate quadrature signals by just using a microcontroller. Will the micro be fast enough to do all the job.i am thinking of using a dsPIC 30 f series which runs at 30MHZ Fcy. Many thanks.
Kind regards,
Sandeep
