Experiencing/Programming arduino UNO another way with USBasp, ICSP, bootloader, AVRISPmk2, settings

Original arduino uno has more options.
Drivers for USBasp chip: zadig.akeo.ie/ (libusbK (v3.0.7.0, this file worked well)

Videos about ISCP/USBasp stuf:
   • How to Use USBasp Programmer with Arduino ...   ( i used this, be aware that arduino board might not get back original state with out downloading different bootloader, in my experiment
normal usb-connection did not worked anymore well/did not upload, so i needed to download make a little trick to get everything back to normal. THIS VIDEO HELPED ME:
   • How to Burn Arduino bootloader to ATmega32...  
)

   • Arduino for beginners. Part 17: SPI  

Arduino software download:
www.arduino.cc/en/software

So uploading with USBasp and using ICSP-port works, but getting board back to normal state is another situation . So use think twice before doing this kind of experiments.


What we learn today:
What's a bootloader?
Microcontrollers are usually programmed through a programmer unless you have a piece of firmware in your microcontroller that allows installing new firmware without the need of an external programmer. This is called a bootloader.
