I'm using Gizduino Atmegamini during my uploading of sample program to the board of arduino, very slow
Cool history bro.
You forget the question
It's obvious from the thread title: "need help".
maybe the VERY slow part is the 'part' needing help with/on?
I'm not familiar with the Gizduino Atmegamini.
Could the OP please post a link to it?
