 Download the [zip file](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/archive/master.zip) of this repository, unzip it in a folder, navigate to the Multiprotocol directory and then click on Multiprotocol.ino. The Arduino environment will appear and the Multiprotocol project will be loaded.
 
-[_Config.h file](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Multiprotocol/_Config.h) must be modified to select which protocols will be available, change protocols/sub_protocols/settings associated with dial for PPM input, different TX channel orders and timing, Telemetry or not, ... 
-This is mandatory since all protocols will not fit in the ATmega328. You need to pick and choose what you want.

 Notes:
 - Make sure to select "Arduino Pro or Pro Mini, ATmega328 (5V,16MHz)" before compiling.
 - Compilation of the code posted here works. So if it doesn't for you this is a problem with your setup, please double check everything before asking.
 - If you want to reduce the code size even further, you can modify the file platform.txt located in "C:\Program Files (x86)\Arduino\hardware\arduino\avr". Set the line "compiler.c.elf.extra_flags=" to "compiler.c.elf.extra_flags=-Wl,--relax".

 ###Upload the code using ISP (In System Programming)
 It is recommended to use an external programmer like [USBASP](http://www.banggood.com/USBASP-USBISP-3_3-5V-AVR-Downloader-Programmer-With-ATMEGA8-ATMEGA128-p-934425.html) to upload the code in the Atmega328. The programmer should be set to 3.3V or nothing to not supply any over voltage to the multimodule and avoid any damages.
