Is it possible to upload arduino bootloader to atmega128?
Which version of arduino should I use ?
I have UsbAsp, can I use it ? How ? I can only upload *.hex file directly from USBasp uploader, but not yet successful on uploading via arduino 1.5 IDE
how can I customize the pin out, as I like ?
I saw pin_arduino.h but I 'm not sure on how to configure it ??
You have to modify it according to the pinout you've chosen.
How can I modify pin_out.h, is there any references ?
