what the benefit uploading hex file merely to arduino board?

Question

What the benefit of uploading merely hex file to avr based board like arduino uno Since the arduino ide it self will send intel hex file to the board after compile .ino file to hex file by the avrdude compiler (https://github.com/arduino/Arduino/wiki/Build-Process)?

• Jot: The data is send to the bootloader, and the bootloader writes it to flash memory. Can you explain your question? What else would you want to upload to the arduino board?
• Doni Mart Galumbang Hutabarat: i just wondering if there is sketch speed execution difference betwen uploading .ino file and uploading pure hex file whether via usb or isp

Answer 1

If you want to upload the same sketch to many Arduinos compiling it again and again would take much longer. Or if you create a firmware ànd don't want to disclose the source code, you can distribute it in compiled form.

• Jot: In some languages an accent can be used to emphasize a word, but the other accent is used (á). What is ànd?
• Juraj: @Jot, I don't know. I wrote it on an Android phone with on screen keyboard which has only English characters
• Doni Mart Galumbang Hutabarat: i just want to know if there is significant speed difference in user program excecution between .ino file and hex file
• Juraj: ino file is not executable. it is a source code. an input for the compiler
• Doni Mart Galumbang Hutabarat: @juraj i do agree with you reffer to link i attached with my question. but when you googling "send hex file to avr board" and some short of that you will find alot talking around that concept. what dou you think
