I have played with QEI. I have two quadrature encoders with index. But where they are? FR4133 was close . And I have made the simple emulator of encoder with index.
I have connected FR4133 with Tiva. P1.3->PD3+PE1 (INDEX&Interrupt) ; P1.4->PD7 (PhB) ; P1.5->PD6 (PhA)
The code from here  and from http://forum.43oh.com/topic/8875-problems-using-qei-with-ek-tm4c123gxl/ was used for Tiva program.

I recently became interested in Finite State Machines and ended up writing a tutorial which has been posted on the 43oh blog:  http://43oh.com/2017/02/how-to-implement-finite-state-machines-using-energia/
 
The example uses Energia but adapting it to C / C++ for use with Code Composer Studio or other IDEs would be simple.  While conceptually easy, working through the details and applying the concepts in a more structured manner were instructive for me.  The tutorial is just an introduction but there are additional references at the bottom.  If you are aware of other good resources feel free to post them below.

I used HAT with USB/COM  cable and have checked up by RasPI test generator.
Excellent.

For those with a dAISy USB or BoosterPack, I just published a new firmware version 4.11 on GitHub.
https://github.com/astuder/dAISy/tree/master/Firmware
 
It introduces the greatest incremental improvement since firmware 4.02. Turns out, slower channel hopping works A LOT better. Same range, but in my tests the change results in about 25-30% more messages received.
 
I also fixed bug in serial communication that only occurs when you try to connect dAISy to an Android device. That bug was introduced a month ago, and impacts only a few customers that ordered units between December 20 2016 and January 18 2017.
 
As always, please let me know if you run into any issues.

It`s for TIVA-C. As is...

@@StrangerM just tried with a MSP430F5529 LaunchPad and it works for me.
 
I tried both ways entering the bootloader, either pressing the BSL button when plugging in or the B command in the debug menu.
 
I can see two potential issues:
 
1) Make sure your firmware file is not corrupted. Some browsers seem to save HTML code instead of plain text when downloading a .txt from Github. I just uploaded them to Github as ZIP file to avoid that issue.
 
2) On my LaunchPad, only the GND, 5V and 3.3V jumpers are in. The other jumpers on the debug connection are empty.
 
Regards,
Adrian

Find code for dAISy and the TMC123G and F5529 LaunchPads with a CC3100 BackPack to send data to MarineTraffic using Energia here: https://github.com/fmilburn3/dAISy_marinetraffic
 
Note that for the F5529 it is necessary to increase the serial ring buffer size in Energia (HardwareSerial.cpp) to get stable operation, e.g. #define SERIAL_BUFFER_SIZE 512.  The TMC123G runs without any modifications to Energia.  It should also work with the CC3200 although I haven't been able to test it with this latest version of the code.
 
And here is a screen capture...

ESP01 consumes too much current. So WiFi is good but USB is better.However,
 
I made upgrade NASA ENGINE3. I inserted the GPS shield with 9600 baud and the Arduino nano (for chenging 9600 to 4800) in ENGINE3. ENGINE3 can insert GPS string with 4800 in 34800 ENGINE3 sending by COM port. I inserted step down converter 12V->3.3V and ESP01 in ENGINE3. ESP01 sends summary signal in WiFi telnet port (23). So there is a new ENGINE3.

hi,
 
this is how to setup an ais server with your rpi, cubieboard or beaglebone, dAISy and Marinetraffic. This is how I did but I'm sure there are better ways to do it ...
 
When you a server @ Marinetraffic,  they'll send an email with IP and unique port where you have to send dAISys output, e.g. 5.9.207.224 7604. We have to redirect dAISy serial output to this IP and unique port with some awful scripts:
 
First, install screen utility: sudo apt-get install screen
 
Plug dAISY USB and check if /dev/ttyACM0 is there; if not, then you need a kernel with support for  CDC_ACM devices;  rpi, cubieboard or beaglebone stock kernels should support these out the box.
 
Test if your dAISy is working with any serial terminal of your choice as minicom or just enter 'screen /dev/ttyACM0'. (CTRL+A and K to exit from screen session). This is how AIS sentences looks like:
 
!AIVDM,1,1,,A,1CF4kT3000Nm`Kl@BHKJC@IH0000,0*37
!AIVDM,1,1,,B,4028jOQur1laeNlMIL@<`8O00@JU,0*5F
 
We'll use this script to redirect serial output to Marinetraffic site; if connection is dropped, it'll reconnect in 5 seconds:
 
#!/bin/sh
while true;
        do
        echo "Start: " `date`
        nc 5.9.207.224 7604 < /dev/ttyACM0
        echo "Restart: " `date`
        sleep 5
        done
done
 
5.- save as /home/foo/ais.sh
6.- run the script in a separate console with this command: "screen -dmS ais sh /home/foo/ais.sh". You can connect with this console with this command "screen -r ais" and kill it with CTRL+A and the press K.
 
From now you can logout and let the box running alone. Add before exit(0) @ /etc/rc.local if you want automatic startup...

Hello. It`s dAISy BoosterPack (thank you very much, Adrian) + GPS USB + RaspberryPI 2 = WiFi AIS+GPS

Hello. It`s dAISy BoosterPack (thank you very much, Adrian) + GPS USB + RaspberryPI 2 = WiFi AIS+GPS

Hello everybody. Several days ago I have received dAISy. It once worked well at my home. I used J antenna.
At my home dAISy works not worse NASA ENGIINE3. But I have checked up also my test generator. And it works well. Zip file includes the short video about it. 
11092015.zip

I made the test generator for dAISy on the basis of the cheap Chinese FM transmitter (http://www.aliexpress.com/item/Free-Shipping-1Pcs-76-110MHz-FM-Radio-Wireless-Transmitter-Module-MP3-Audio-Repeater-Module/2042607191.html ) and wav files with AIS  signal. In the transmitter I have changed the coil and the capacitor. I have changed its frequency having used for control DVBT USB and SDR Sharp
The test generator is not so useful. As it has bad temperature stability and is difficult at adjustment. Nevertheless.

A decoder (AIVDM -> coordinates, speed etc.) is very interesting. If to add  GPS shield we can get a alarm device of dangerous closing.
I have made a draft variant of such decoder for 1 type of message. :-) CMX589+TIVA-C+wav

I have made a draft variant of such decoder for 1 type of message. :-) CMX589+TIVA-C+DVBT+SDR SHARP+J-antenna

OK. Good news. It are some my steps. Your project -> Energia. Tekmanoid->Arduino. And It`s my boat (Stranger :-))

Thanks you!
There is a photo of already finished device.
I  did the project simply. I collected all C-files in one. So it  turned out better because of features of the Energia compiler. I added h-files in the project. I changed interrupt operators and input-output operators. It does not look well, nevertheless the device works. Now the project is disorder and contains errors. Therefore I would not like to publish it, but I can send it to you (as author of the project :-)).
PS Sorry. I collected not all C-files in one. And I added not all h-files in the project. I used needed files from your project. It was in April (or May)and I don`t remember everything well.
