  1. Model of LaunchPad: MSP430G2553/G2403 and revision number: 1.5 Model of the MCU used: I am not sure, but the box is MSP-EXP430G2 Name and version of the IDE used : Energia version 0101E0017 (I tried the newer one, but it threw a bunch of errors which resolved when downgrading) OS the IDE is running on Ubuntu 16.04 LTS I am completely new to this type of programming, so I apologize if I need extra clarification or am missing something. Issues faced: The blinking code I have used all work just fine, but no print statements work. My current goal is to simply get a read from the internal temperature sensor, but printing won't work. I am attaching relevant screenshots. and example code. Any direction/help is appreciated! Blink.ino
  2. Hi everyone. I am new to Energia, but I have used the Arduino IDE a bit. I am trying to use Energia to work with the MSP432 launchpads I just bought on sale, My environment is Ubuntu 14.04.3 LTS (trusty). I just downloaded the latest version of Energia from energia.nl (0101E0017). I ensured I have permission to access the serial ports. The only changes I've made is to select the tools -> serial port (when i had the MSP432 launchpad connected) and to select the tools -> board. I chose to run the example 'blink' code. When the MSP432 is selected I receive an error. When I chose a 430 board it compiled without error. The error with the MSP432 is Cannot run program "make" (in directory "/home/username/energia-0101E0017/hardware/common"): error=2, No such file or directory I verified the directory exists, and there is a Makefile in there (but no make file). The Makefile has content (it seems like it is written correctly but I'm not a Makefile expert). I copied the Makefile to make, just in case. but I still get an error. I saw where MSP432 users on windows were having issues due to spaces in directory names, but I don't have any spaces (can you in linix?). Any suggestions? I would hate to have to pull out my old windows laptop just to work on the MSP432. I'm using Energia because my very reluctant kids (15 yo and 12 yo) have agreed to make a mini project on the MSP432s I picked up. I don't want to try to get them to learn CCS Thanks for any assistance. I do appreciate it.
  3. I have beaglebone black install ubuntu 13.04, i wanna send a data to LM4F120XL and receive data from it, have anyone used to do it? plz give a suggest or a tutorial ?

    BeagleBoardXm Home Energy Monitor

    Over the past 10 years I've used various micro-controllers and devices to monitor and control my home heating and cooling system, water heater, sump pump, humidifier, AC power, lights, as well as a custom security system. After downsizing and moving into a condo a couple years ago, I also downsized my system toys, much to my wife's relief. But I am currently using a BeagleBoardXM to monitor our gas furnace and relevant weather datapoints. I thought I would share some of this project with anyone who might be interested. The heart of the monitoring system is a BeagleBoardXm running Ubuntu 13.04 headless. The program itself is written in Python 2.7.4. Data passed to the program consists of whether the furnace's gas burner is on or off, the temperature and humidity inside our home and the temperature, wind chill and wind speed outside. These 6 data points are uploaded to Xively every 60 seconds where they are automatically graphed for web analysis. In addition all data is logged to the BeagleBoard's SD card everytime the status of the furnace changes. To be more specific about the hardware, a 24VAC relay is connected to the furnace's gas valve. It's normally closed contacts are connected to a digital input pin on a Xbee radio module. The Xbee is set up in I/O line passing mode. When the furnace fires, pin D3 goes High, which is reflected on another Xbee, also running in I/O line passing mode, connected to a USB port on the BeagleBoard. This Xbee then sends a 13 byte packet to the serial port which is read by the Python program. I could add more appliances to the Xbee in our utility room, for example, the water heater, clothes washer/dryer and AC power. But for now I'm keeping things minimal. To measure the temperature and humidity inside our home, I'm using a Phidgets 8/8/8 Interface Board. Phidgets temperature and humidity sernsors are connected to a couple of its analog inputs. Here again I could add more sensors. To get outside conditions, I'm pulling down metadata from WeatherBug.com, parsing its 30 some data elements and retreiving just temperature, wind chill and wind speed. Those seemed to be the things most relevant to how much my furnace runs. Then as I mentioned, these 6 data elements are uploaded to Xively.com for online viewing. This has come in handy when we are away to make sure things are running OK at home. Here's a link to my account: https://xively.com/feeds/97217%C2'> It may not always be updating, as I fiddle around with the program. I use MobaXterm to SSH into the BeagleBoardXm and WinSCP for more extensive file management, both from my Windows machine through our home network. I did find it necessary to setup a static IP adress for the BBXm. Some of the Python packages this project uses are: PySerial, Mechanize and Phidgets. I'm using an embedded class from: github.com/mattvenn/cosm to format the data elements into a format suitable for uploading to Xively. Interestingly, Pachube was bought by Cosm and finally by Xively during the years I have been using them to graph my data. I also managed to get my sound working and may use it for audible warnings or messages. Perhaps more to come...
  6. I can't seem to be able to install bonescript on my BBB. I'd appreciate any help. Thanks. I installed ubuntu because I could not get HDMI to work with Angstrom even with the latest image.
