What are fuses? How to work with fuse bits on AVR microcontrollers
In this video we will talk about what fuses are, what they are for and how to work with fuses on AVR microcontrollers. In the video I will demonstrate the fuse calculator and how you can change fuse bits with the fuse calculator.
I will show an example of changing the fuses on the ATtiny13 microcontroller. But this method will work for other AVR microcontrollers too. In the video, I will first change the fuse of the CKDIV8 and show what happens. And then I will show the result of changing the RSTDISBL fuse. And you will see how easy it is to increase the number of available I / O pins by one.
An Arduino UNO is used as an ISP programmer with a module placed on top for the convenience of firmware ATtiny microcontrollers.
