thanks for the reply..
this can not (should not) be a chip by itself project... IMHO..
I mean I need it to be small.. but I want it to work and be somewhat stable! lol
Since it will be running @ 3.3v & INTERNAL 8Mhz clock... I dont need the caps/crystal.......correct?
RESET pin broken out (for easier flashing/uploading)
DTR pin broken out (for easier flashing/uploading)
AREF pin (correctly set-up... I see in the schematic Crossroads posted.. he has the AREF pin connected to GND through a cap... but I do NOT need to connect to the 3.3v for a voltage refeence? Just keep it INTENRAL reference at the 1.1v or whatever?)
and of course I want to ensure that I 'correctly' set-up the battery/power input..
since there will NOT be any voltage regulator (battery supply will be within the 3-3.7v range max).. but I want it to be stable..no ripples.
follow same principles or ceramic/polarized cap on the input power lines?
Despite what the symbol is, caps less than 1 uF are typically unpolarized, and >= 1 uF
are typically polarized.
thanks!.. rules like this help a noob like me.
I am still wrestling with 'decoupling'.. and 'KNOWING' when to use a certain component or not (like when to use ceramic vs polarized..etc)
hopefully I can get to a more final version tonight/tomorrow.. and I'll post for review..
appreciate all the discussion guys!
