Arduino ISP for flashing Turnigy 9x radio

Why use this?

Because there's a problem when calculating the address while reading/writing the EEPROM. When you try to backup/restore models using OpenTX Companion you will get a corrupted EEPROM message. That's not true! Load this sketch on your Arduino and it will work. NOTE: I tested and used this on Arduino Mega 2560.

I found the fix online, at the end of this file the url!

How to fix on your own: Remove the "* 2" in "int start = here * 2;" in functions "eeprom_write" and "eeprom_read"

After this modification your lines will looks like this: "int start = here;"

When flashing the firmware everything works fine!

I found the fix online, i can't remember which website. I will post it here when i will find it again.
