    Let us know if you come across any other issues that are either not clear or you think is a bug. This will help us a lot with improving the code or documentation.

    Energia uses Timer output to generate PWM signal with varying duty cycle. P1.0 aka RED_LED is not on a timer output and hence analogWrite to that pin will not work. What it does instead is either set the pin high or low depending on the value written to it.
    See the hardware pin mapping guide for what pins can be used for what functionality: https://github.com/energia/Energia/wiki/Hardware

    Still a work in progress.
     
    The Stellaris To Breaboard BoosterPack allows you to use your Stellaris LaunchPad in a breadboard (a double wide one). Stacks on the bottom

    Kits shipped. Only Athuli is left as I have no address.
    International orders:-
     
    I had to remove the kit from the box and put it into a bubble envelope to save on shipping. It will reach you , no worries.
    Thanks for participating!

    Thats right, start with the code, and if you have doubts keep posting.
     
    If there is no ambition there is no motivation to work and learn

    Hours of video and training for the new kit. Including some for the display booster.
     
    Looks like you can attend live versions or watch most of it as videos online.

    abecedarian reacted to bluehash in Look what TI sent over to review...   
    More info.. Although you can get these from the videos now:
    - Awesome RGB LED
    - JTAG pins are brought out to TCK,TMS,TDO,TDI,EXT_DEBUG and RX, TX lines.
    - Device/debug switch
    - Alot of GND and 3.3V test points to sip off.

    Java syntax is not that much different then C. If you can read Java you can probably read C. Writing it will take some time and practice. If you have figured out that many other languages adding C won't be hard. Kernighan and Ritchie's C Programming Language is the defacto standard book that everyone seems to think they need on the shelf. More of a reference than a tutuorial though. See the long list of examples in the StellarisWare download that I linked to before in this thread. Most are one or two files and should help get you started.
     
    There is an effort to get Energia working on the Stellaris LaunchPad which would open up the Arduino language/API but that may be just one more thing to learn that is somewhat limited. Also I don't know what the schedule is for that effort.
     
    As for IDE's: IAR and Keil are both proprietary and limited unless you pay a good chunk of money. The editors and environments are theirs and would require some learning. If you know Java, you may know eclipse. If you know eclipse then i suggest either Code Composer (TI) or Sourcery CodeBench (Mentor Embedded). Both run in an eclipse environment. On previous kits TI has made Code Composer free and unlimited for use with the kit. Only pay if you move to your own design.
     
    Good Luck and welcome to MCU's.

    My proposed project:
    Create an easy to use interface with an engine control unit via CAN, permitting on-the-fly programming and adjustments to the ECU in addition to providing real-time feedback and display of engine operating parameters.
     
    My reasoning behind this:
    I am installing a Mega/Microsquirt system on my motorcycle and tuning the unit with a laptop isn't as easy as doing such in a car. The recent MS units have CAN support so this seems to be a natural way to extend it and interface with it. A unit such as I am planning would permit relatively easy adjustment to the ECU- a small(ish) unit mounted on the handle bars providing an interface to the tuning aspects, and similarly being capable of providing a monitor of vital engine functions.
     
    I am also planning on using the soon to be released Stellaris LM4F as a general "dashboard" - displaying speed, fuel level, RPM's and such, as well of the possibility of interfacing the two together, providing things such as fluid monitoring and warnings, up and down shift indicators, fuel consumption and other maintenance reminders in order to provide a comprehensive vehicle tuning and monitoring system.
     
    I know that, in order to be a viable solution, abstraction is required- dependent on hardware being interfaced with. Anyone who has looked at Megasquirt knows everything about it is quite abstract. This unit would provide the abstraction layer between the ECU and the real world.
     
    The dashboard side doesn't require so much abstraction since the sensors are not vehicle specific and would require "calibration" regardless of the vehicle. Sensing vehicle speed requires regular signals from a wheel sensor, RPM's can be sensed from ignition coil sensing, fuel level would depend on the sensor (capacitive or resistive and its range), temp sensors are resistive, etc... all relatively easy to handle via ADC.
     
    Being able to combine the "dashboard" with "ECU"-related information could result in a comprehensive system to monitor, tune and otherwise optimize a vehicle's operation... in my specific case, a turbocharged motorcycle (Honda CX500TC), but could be similarly adapted to work with any CAN-enabled ECU and even many OBDII vehicles.
     
    I'm not sure though, what I would do with the Ethernet capability, but I could imagine being able to connect to a laptop or such for datalogging purposes would be helpful.
