+These are KiCad files and you are free to do what you will with them. KiCad is a good, free, and fairly
+easy to learn.  Build your own BOM and gerber files.
+
+This is a variant of the Multipro V2.3c circuit design.  It is basicly the same as the 2.3c board as far
+as component placement goes.  What's changed is the added resistors for the serial protocol and also
+the addition of solder jumpers on the bottom of the board for the various options to connect the TX, RX, and PPM
+lines through them. See below for more detail.
+
+The schematic has been updated to reflect the added components and jumper pads as well as cleaned
+up a little.  As it sits now, the .net file loads without any complaints and DRC checks pass.
+
+The jumpers, and how they are used:
+	
+
+There are four solder type jumpers on the bottom side of the board near the lower left corner when the
+bottom of the board is facing towards you. The silkscreen shows which jumper is which. These four jumpers 
+enable the board to be configured in several ways as explaned below.
+
+	(J-1)	Use (PPM V/V) if the incoming PPM signal is at a higher voltage level, leave open if ~~5V.
+
+	(J-2)	Use (Jumper 2) to connect the incomming PPM signal to the RX pin on the processor
+
+	(J-3)	Short (TELEM) only if you have done a telemetry mod to your radio, leave open if not needed. When
+		connected, pin 2 of the two pin header (P3) is also connected.
+
+	(J-4) Use (MOD) only to connect the transmitter pin 2 to pin 1 of the two pin header (P3).
+
+The direction this project is going, it is most likely J-2 will be the only one needing to be shorted for
+the serial method of sending model protocols.
+
+
+These files are submitted without any guarentee of accureacy or suitability for any intended use.  I am strictly
+an amature with time on his hands. Although I have done all I know to make it correct, things outside of my
+knowledge base are beyond my control.  Do not use untested equipment around persons not familiar with the hazards
+of remote controlled vehicals.

+You can access to up to 15 different protocols and associated settings.
+ 
+Settings per selection are located in _Config.h:
+ - Protocol and type: many main protocols have variants
+ - RX Num: number your different RXs and make sure only one model will react to the commands
+ - Power: High or low, enables to lower the power setting of your TX (indoor for example). 
+ - Option: -127..+127 allowing to set specific protocol options. Like for Hubsan to set the video frequency.
+ - Autobind: Yes or No. At the model selection (or power applied to the TX) a bind sequence will be initiated
+ 
 ###Using a serial output

 Notes:
  - Using this solution does not need any modification of the TX since it uses the TX module slot PPM pin for serial transfer.
- - There are 2 versions of serial protocol either 8 or 16 channels. 16 channels is the latest version. Make sure to use the right version based on your version of er9x/ersky9x.

 ###Telemetry
-Telemetry is available for er9x and ersky9x TXs.
-There are only 2 protocols so far supporting telemetry: Hubsan and Frsky.
 
-To enable telemetry on Turnigy 9X or 9XR you need to modify your TX following one of the Frsky mod like this [one](http://blog.oscarliang.net/turnigy-9x-advance-mod/).
+There are 3 protocols supporting telemetry: Hubsan, FrSky and FrSkyX.
 
-Enabling telemetry on 9XR PRO and may be other TXs does not require any hardware modifications. The additional required serial pin is already available on the TX back module pins.
+Hubsan displays the battery voltage and TX RSSI.
 
-Once the TX is telemetry enabled, it just needs to be configured on the model as usual.
+FrSky displays full telemetry (A0, A1, RX RSSI, TX RSSI and Hub).
+
+FrSkyX displays basic telemetry (A1, A2 and RX RSSI).
+
+### If used in PPM mode
+
+Telemetry is available as a serial 9600 8 n 1 output on the TX pin of the Atmega328p using the FRSky hub format.
+
+You can connect it to your TX if it is telemetry enabled or use a bluetooth adapter (HC05/HC06) along with an app on your phone/tablet ([app example](https://play.google.com/store/apps/details?id=biz.onomato.frskydash&hl=fr)) to display telemetry information and setup alerts.
+
+### If used in Serial mode
+ Telemetry is built in for er9x and ersky9x TXs.

 ###Toolchain
-Arduino 1.6.5
+Multiprotocol source can be compiled using the Arduino IDE.
 
-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.
+The currently supported Arduino version is [1.6.7](https://www.arduino.cc/download_handler.php?f=/arduino-1.6.7-windows.exe).
 
-Multiprotocol.ino header can be modified to compile with/without some protocols, change protocols/sub_protocols associated with dial for PPM input, different channel orders, different channels timing, 8 or 16 channels serial protocol, Telemetry or not, ... 
+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.

+####Input Mode - PPM
+- The protocol/mode selection must be done before the power is applied.
+- Connect 1 to 4 of the selection protocol pins to GND.
+
+####Input Mode - Serial
+- Make sure you have done the mods to the v2.3c PCB by adding the 2.2k and 470 ohm resistors as indicated in the [Board section] (https://github.com/pascallanger/DIY-Multiprotocol-TX-Module#board).
+- Leave all 4 selection pins unconnected.

 ###Bind
 Make sure to follow this procedure: press the bind button, apply power and then release it after 1sec. The LED should be blinking fast indicating a bind status and then fixed on when the bind period is over. It's normal that the LED turns off when you press the bind button, this behavior is not controlled by the Atmega328.
 For serial, the preffered method is to bind via the GUI protocol page.
 
 It migth happen that your module is always binding at power up. If this is the case, there is a big chance that you are using an Arduino Pro Mini with an external status LED. To work around this issue connect a 10K resistor between D13 and 3.3V.
