dsPIC33EP512MU810

[kalyan]

I am developing a board using dspic33ep512mu810 ic. My doubt is whether ccs compiler supports this ic and all functions work without any problem.

Manly i2c, uart, qei.

Kindly share your feedback if you worked with this ic.

That's quite an 'old' chip. Been supported for at least a couple of years.

However three things:

1) CCS generally fully supports 'standard' functions, but if you start doing complex things (mixes of DMA, and sample triggers for example), these will need you to set large parts of these up yourself.
2) Generally it takes a couple of releases for some bugs in configurations to be found. However this one has been around long enough for these generally to have been spotted, but it only takes you to be trying a combination no-one else has used, for one to rear it's head.
3) This chip has a huge number of errata. Some have _no_ work round. Be careful to make sure that one of these will not affect your project. The QEI/comparator in particular have issues with virtual pin mapping. Some are really horrible, and make parts of the chip almost unusable (for instance the USB one - problem is on most modern motherboards, the USB peripheral is permanently mapped via an internal hub in many cases...).

Which dsPic has less number of errata issues ? Kindly suggest.
I am going to develop a board for industrial servo control.

Depending on 'system requirements' a dsPIC might not be needed. 20 years ago we designed a 3DOF helicopter using the 16F877 using optical encoders and DC motors. It was interesting to see it being controlled, in realtime, over the Internet.
