Assalamu’alaikum Guest, here i will tell you about How Lock .hex file in Microcontroller or Arduino using Extreme Burner, did you think that your program in microcontroller can be copied by someone? certain that matter you not expect, therefor at this time cronyos.com will share so it does not happen. let’s begin.
Materia needed :
- USB ASP
- Microcontroller would you lock
after you have materials above you can follow any steps below.
First, you must download and Install Extreme burner.
after you download and instal Extreme burner, you should conect your USB ASP to Microcrontroller (MISO, MOSI, SCK, Reset), then open Extreme Burner.
Choose your Microcontroller chip, here we using ATmega 328p (Arduino UNO)
in Write Tabs choose > Fuse Bits and Lock Bits > tick “Lock Fuse” and fill “C0” (C and Zero) and than click Write
after you finish all of step above, if someone try read flash or read your .hex program in your microcontroller chip they won’t able to do it.
