As many people said, PIC is good, but you need to buy/build a
programmer (ie. PIC ICD, PICSTART plus or others).
Alternately, there's many other choices. For example, you can buy a
HC11 or HC12 EVB (Evaluation board), they can be very small,
including the header with all the pinouts on a little board. All you
need is the free assembler software (or find a free C compiler like
the GNU compiler) and a serial cable (which is probably included in
the EVB kit). A lot of companies online sells these HC11 EVB. This
place has a very good selections and i bought from them before:
In my opinion, PIC is easy to use once you get the hang of it, but
HC11/12 seems to be a bit more powerful than the PIC16 series. You
have 2 accumulators and 2 index reg in hc11 and you get 1 of each in
Also, for very inexperience users, you may find a parallax BASIC
stamp useful. They are popular among hobbyists. I think they are
good for small projects and hobbyists, but not for developing a cheap
product. they are also single threaded.
