                                I've never liked PICs.  They're slow,
                                expensive and very hard to develop for,
                                thanks to the sheer lack of support -
                                and last time I looked you had to pay
                                extra for surface-mount!<br>
                                <br>
                                I used AVR for a bit but I'm moving over
                                to STM32 - ridiculously cheap and
                                ridiculously fast.<br>
                                <br>
                                This must be a personal taste thing, as
                                I have no problems at all programming
                                with PICs.  The documentation is very
                                good, and there are lots of examples to
                                get over the most difficult part which
                                is how to set the various switches (in
                                AVR world the equivalent is the
                                "fuses").  I've actually had more
                                frustration figuring out how to set
                                fuses, to be honest.  I haven't played
                                with the STM32s, I'll certainly have to
                                give that a try.<br>
