stk-200
note
: in stk-200 rev.c have a serie resistor of 10k in serie whit
port-b output
pin 5,6,7 this cause bug if you use this pin at higt-sped end as input
juste short pin on sip resistor near port-b deconect isp conector after
use
: if you use like me a lcd tha
must have a negative bias for contraste just
cut trace of the gnd of the pot (top side
just in fromt of pot under yello paint)
end jump this pin to pin 5 of max-232 now
you have a contras of -5 to +5 volt
: for precaution in sujest to
add a resistor end a zener diode in the dongle
for protec your computer if volt reg (78l05)
of stk-200 burn it put 10 volt
in lpt port of
computer this cost me a thinkpad ...
atmel starter kit
: just add a isp conector
(male 10 conector) remore 7805 reg end voila
you have a serial programer to program your stk-200 from avrstudio 3,2
: if you have comment or
sujestion drop me a mail -))
