If you buy a starter kit... For any micro you should have enough to get you started.... Years ago, when I started ( No internet) I bought a 8051 development board... It came with a chip, an assembler a C compiler (lite) and quite a few sample codes.... It was enough to get me into micros.... Then conversing with a certain Uni professor, I managed to get an application to market..
You first need to look at several micro PDF's and choose which one will suit your needs (and pocket)... Then return here and let us know
