+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.

+Bind procedure using serial:
+- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
+- Turn on the TX, set protocol = Devo with option=0, turn off the TX (TX is now in autobind mode).
+- Turn on RX (RX LED fast blink).
+- Turn on TX (RX LED solid, TX LED fast blink).
+- Wait for bind on the TX to complete (TX LED solid).
+- Make sure to set the RX_Num value for model match.
+- Change option to 1 to use the global ID.
+- Do not touch option/RX_Num anymore.
+
+Bind procedure using PPM:
+- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
+- Turn on RX (RX LED fast blink).
+- Turn the dial to the model number running protocol DEVO on the module.
+- Press the bind button and turn on the TX. TX is now in autobind mode.
+- Release bind button after 1 second: RX LED solid, TX LED fast blink.
+- Wait for bind on the TX to complete (TX LED solid).
+- Press the bind button for 1 second. TX/RX is now in fixed ID mode.
+- To verify that the TX is in fixed mode: power cycle the TX, the module LED should be solid ON (no blink).
+- Note: Autobind/fixed ID mode is linked to the dial number. Which means that you can have multiple dial numbers set to the same protocol DEVO with different RX_Num and have different bind modes at the same time. It enables PPM users to get model match under DEVO.

 ###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 4 protocols supporting telemetry: Hubsan, DSM, FrSkyD 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.
+DSM displays TX RSSI and full telemetry.
+
+FrSkyD displays full telemetry (A0, A1, RX RSSI, TX RSSI and Hub).
+
+FrSkyX displays full telemetry (A1, A2, RX RSSI, TX RSSI and Hub).
+
+### 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 for Hubsan, FrSkyD, FrSkyX and DSM format for DSM2/X.
+
+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.
+
+To enable telemetry on a 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/).

+Repository includes Kicad files of schematic and pcb. 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.

+This module can be purchased [here](http://www.banggood.com/2_4G-CC2500-A7105-Flysky-Frsky-Devo-DSM2-Multiprotocol-TX-Module-With-Antenna-p-1048377.html). All the 4 RF modules are already implemented A7105, NRF24L01, CC2500 and CYRF6936. The board is also equiped with an antenna switcher which means only one antenna for all.
+
+**It is highly recommended to update the firmware** of this board as it is distributed with a really old and bugged one. For this you have to solder a 6 pin header (top left) and use an USBASP like explained [below](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module#upload-the-code-using-isp-in-system-programming). 
+
+If you want to enable serial mode for er9x/ersky9x/Taranis/... and depending on your board revision, you have to do one of these modifications:
+- 1st revision, add 2 resistors as shown here: ![Screenshot](http://static.rcgroups.net/forums/attachments/4/0/8/5/8/3/a8895038-170-4in1%20module.jpg)
+- 2nd revision, solder pads together as shown:

+
+Note: if you have the 1st board revision (check pictures above), sometime bind occures at power up even without pressing the bind button or not having an autobind protocol. To solve this issue, replacing the BIND led resistor (on the board back) of 1.2K by a 4.7K.

 ##Compilation and programmation
 
 ###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 [1.6.10](https://www.arduino.cc/download_handler.php?f=/arduino-1.6.10-windows.exe).
 
-_Config.h file can be modified to compile with/without some protocols, change protocols/sub_protocols/settings associated with dial for PPM input, different channel orders, different channels timing, 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.
+
+**[_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 available 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.

 ###LED status
 - off: program not running or a protocol selected with the associated module not installed.
-- flash: invalid protocol selected (excluded from compilation or invalid protocol number)
-- slow blink: serial has been selected but no valid signal has been seen on the RX pin.
-- fast blink: bind in progress.
+- flash(on=0.1s,off=1s): invalid protocol selected (excluded from compilation or invalid protocol number)

+- fast blink(on=0.1s,off=0.1s): bind in progress.
 - on: normal operation.
 
+###Protocol selection
+####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.
