reading datasheet

I read detasheet that was written by Japansese. But, didn't understand well other than pin assignment.

preparation

I removed jumper using two soldering iron and remover for change mode to writing.

preparation

then , connected ISP and hello-borad. their power from USB and FDTI.

connected ISP and borad

writing code

I know about AS220's tutorial in academy class's ML, so I reviewed it. It was perfect.

C

I tried running C code first. Before build C, I wrote fuse to AVR.

c code

check in serial monitor on arduinoIDE. and it worked.

test

arduinoIDE

I used high&low tech site as reference. I set bord,port,ISP. And change pins on program compare with datasheet.

ArduinoIDE

it worked.
