Hi guys,
I trying to run an standalone Atmega328p with 3.3v and external clock (8Mhz).
i followed the CrossRoads's way that is burnbootload "ProMini, 3.3 V 8 MHZ" board first.
i use an USBISP interface to do it and i feed it with 3.3v.
Unfortunatly after burnbootload, i upload "blink" sketch to test it and i haven't any sign of good work except in 5v.
What am i doing wrong ?
