[sdiy] Microcontrollers, development environments and hardware programmer recommendations.

[Ben Riggs]

hey guys, i’m so appreciative of the input and i am looking at all the recommendations.

As i mentioned earlier, where my last exposure to hardware micros was programming PIC a least 10 years ago. Started off with UV erasable 12C508 (i remember that UV part cost me $60, the OTP was a penny) then onto 12F, 16f then some 18f chips.

the initial micro concepts that i had in mind were based on this, so the whole feature set of the 32bit micros and seriously even the (what seems now outdated) the DSPIC are too much.

The reality is the PICKit3 will do what I need now, it’s what i already know and what my ideas that i want to implement are based on. if later on i need something more I can already see now that I shouldn’t be overwhelmed as the options are inexpensive and well supported.

Thanks.
