PIC's are good, I have a few 16F877's here atm, but if you want somethin to
run REAL fast, dont use a basic compiler, the code tends to be a bit fat &
sweaty, if you wanna do it properly, learn asm, its not too hard just
requires a little extra brain power... if speed is not an issue, C all the
way if you already know it, or learn asm if your new... as for your line
about the hc11's... I just completed semester 1 of my 1st year of electrical
engineering and i learnt assembly on the 68hc11... it's still being taught
to this day... if you want to get a cheap development board for different
processors try www.futurlec.com and try under kits & devel boards....
anything from AT to PIC to HC11 development boards, I bought the hc11...
