    I have the RPi3. It controls all my sprinklers and is automated via open sprinkler.
    I spent two days setting it up and it is now in my home crawl space.
    It connects to my home wifi, so I can connect to it from anywhere(through a port forward).
     
    The only thing I bought for out was the relay board.

    Understandable.
    Code is here: https://github.com/rszimm/sprinklers_pi/wiki (I did not write it)
    I wanted something that I can setup quickly and is highly configurable and it works reliably, because my plants would not like it otherwise... and it has.
    I ssh it into it every week to make sure all is well and hope to add more home automation functionality in the future. The only time it has gone down in the last 2 months is due to a power blip and it did not boot up well.
    It looks at the current weather(temp, humidity, rainfall).. and uses an equation to figure out the water requirement... pretty cool.

    bluehash reacted to energia in REALLY? main() not found ? MSP432 Launchpad   
    Thanks for reporting this and sorry for the inconvenience this is causing. This should be straight forward and would very much like to get to the bottom of this. So please bear with me while we try to get to the bottom of this.
     
    I tried to reproduce it on Windows 10. But am not able to reproduce the issue (see steps below). You might have hit a corner case that we might not have caught. Would really appreciate it if you could provide details such as Sketch name, Sketch folder saved to, what is in that folder, etc. Anything helps. I'll then use those details to try and reproduce it. Would be great if you could try the below and see if that works.
     
    Can you please also copy paste the entire output of the black log window in this thread for both the fail and success case? Before you do so, please turn on "Show verbose output during [ ] compilation". Hopefully that will provide additional clues.
     
    This is what I did in an attempt to reproduce the issue.
     
    Open File->Examples->01.Basic->Blink File->Save As... Saved it to Desktop/Blink. This should produce a folder Blink on your Desktop with a file Blink.ino in it. Then Sketch->Verify/Compile This works as expected, the file compiles and produces an .elf file but obviously I am missing something in my steps that makes it fail in your case.

    Everyone,
     
    I am new to the Energia platform. I am a professional embedded developer, so rarely use Arduino like tools, well never Unless I am trying to teach someone how to get started. That said, I have a project that I was coding in TI Code Studio for a client, then I thought on this next project, much simpler, I would use Energia, so they could actually make changes to it -- 
     
    Anyway, I downloaded the Energia ZIP latest, there is no installer, so unzipped into directory. I then set it up, board selected MSP432 Launchpad, then started trying examples. Everything works perfectly.
     
    However, when I take ANY project, blink, you name it and save as and place into another directory, ANYWHERE -- then re-compile, I get:
     
    C:\Users\Andre\AppData\Local\Energia15\packages\energia\hardware\msp432\1.3.3\cores\msp432\gnu/targets/arm/rtsv7M/lib/boot.am4fg(startup.om4fg): In function `startupC':   /db/vtree/library/trees/zumaprod/zumaprod-n06/exports/tirtos_full_2_20_00_06/products/bios_6_46_00_23/packages/gnu/targets/arm/rtsv7M/startup.c:76: undefined reference to `main'   collect2.exe: error: ld returned 1 exit status   exit status 1 Error compiling for board LaunchPad w/ msp432 EMT (48MHz).   In other words, the linker can't find main() -- so I am thinking, someone HARD coded a path somewhere and at this point, I can't save anything and then run it. Currently my work around is:   1. Open any example project, compile, upload, test it, works. 2. Take my source and copy into IDE, then compile, upload, it works. 3. IF I then try to save, I get read only, since the examples are flagged read-only, thus I save as another name, in a number of directories, no matter what, THEN when I try to compile I always get:   C:\Users\Andre\AppData\Local\Energia15\packages\energia\hardware\msp432\1.3.3\cores\msp432\gnu/targets/arm/rtsv7M/lib/boot.am4fg(startup.om4fg): In function `startupC':   /db/vtree/library/trees/zumaprod/zumaprod-n06/exports/tirtos_full_2_20_00_06/products/bios_6_46_00_23/packages/gnu/targets/arm/rtsv7M/startup.c:76: undefined reference to `main'   collect2.exe: error: ld returned 1 exit status   exit status 1 Error compiling for board LaunchPad w/ msp432 EMT (48MHz).     I am getting frustrated here, the whole point of this was to try and give the customers something they might be able to put hands on, but this IDE needs to be solid --    Anyway, any help or suggestions would be appreciated.    This should work out of box, "saving" the project should NOT break the application and IDE loose track of the build process, etc.    Andre'

    bluehash reacted to JeysonZG in [Energia Library] Ping4Pins: For 4-pins and 3-pins PING sensor   
    - INTRODUCTION
     
    Hi everybody, I want to share a library for controlling a 4-pins PING sensor (HC-SR04 ICStation) basically, although you can also control the 3-pins PING))) sensor conventional of Parallax (URL). 
     
    This library is a modification of the Caleb Zulawski's library for PING))) sensors. I made basic improvements in calculations, I added a function to calculate the distance in millimeters and added the option to change the "input trigger signal" [10uS for HC-SR04 and 5uS for PING)))]
     
     
    - CHANGE LOG
     
    v2.1 (26/08/2014)
     
    * Fixed calculations of distance in inches.
     
    v2.0 (25/08/2014)
     
    * Fixed problems with measurements adjustments.
    * New function for modification of a single unit.

     v1.0 (24/08/2014)

    - INSTRUCTIONS OF INSTALLATION
     
    1. Download the latest version of the library
    2. Unzip the zip-folder. 
    3. Copy the "Ping4Pins" folder in the location of the libraries depending of your trainer:
      * For Arduino: <Arduino IDE directory>\hardware\libraries\
      * For Tiva C: <Energia IDE directory>\hardware\lm4f\libraries\
     
    Note: If you used an older version of the library, I recommend deleting the folder and copy the new folder "Ping4Pins".
     
    - EXAMPLES SECTION
     
    In the "examples" folder are 5 examples for Arduino and 5 examples for Tiva. I'll post the example # 1:

    I like the boosterPack concept, but for my current project I needed access to all the pins on an F5529 as well as an F2013.  So, I constructed a couple of boards to plug into an MSP-TS430PN80USB in a boosterpack fashion. As is  probably obvious, I missed a couple of traces (GND lines), for which I had to add the little green wires. The top board has all my sensors, and the bottom is basically battery management and a sx1509 port expander to manage a number of LEDs.  I don't actually need the extra ports, but I wanted the sx1509's built-in LED "breathe" capability. Saves coding... -lazy programmer
    I was a happy camper when I fired-up the system and was able to access and program both MCUs.
    I've found that I can choose between running two instances of IAR (or CCS) and debug both micros simulaneously.  Handy for the comms and interrupt handing.
    So, let the fun begin...
     
    BTW - the TFT LCD is from buydisplay.com - 2.8" TFT with Cap touch (about $15.00 U.S.).  It's using the ILI9341 controller for the LCD and the FT6206 controller for the cap touch.  For proof of concept I was able to use the Adafruit sketches to connect with both, and the edits were limited to pin assignments, if I remember correctly.

    bluehash got a reaction from spirilis in `Bare Metal` BeagleBone Development in Linux   
    Well. Recently I tried setting up CCS for bare betal BBB programming. TI is currently going through a phase of moving their BBB Starterware package to TI-RTOS ProcessorSDK. Unfortunately I ran into too many issues getting their tool chain to work correctly. I gave up and moved to another processor because this project was time critical. There are no readmes for the projects. Build's break and not documented. The learning curve is a bit steep. It is not ready for prime time yet.
     
    Now your issue is more to do with using JLink with CCS on linux. Firstly, JLink will work on CCS for the TivaC family, at least on windows. JLink for BBB on CCS is not supported, even on windows.
    I had to buy an XDS200 to get code pushed into the BBB.

    It's a dual mode Sub-1GHz and BLE wireless launchpad. The US version seems to be available now, but the EU version is not yet available. I assume this means that it's not switchable between the US (915MHz) and EU (868MHz) band for the Sub-1Ghz bit.
