    simple. common transistors like pn2222 should work.
     
    msp430 pin is the arduino pin etc. 5v to switch the relay up the top. connect the grounds together on your 5v and msp430's 3v supply. can also add a capacitor next to the diode if getting noise issues

    Timerserial works on the 2553 just fine. You just have to create an instance with a name other than Serial.
     

    #include <TimerSerial.h> TimerSerial TS; void setup(){ TS.begin(9600); } void loop() { TS.println{"Hello World"); delay(1000); }

    There is a known issue with the CDC drivers in linux. something about a buffer overflo when no one is listening (work around is dont send data before you have something listening to the com port, or apply the CDC driver patch and reload the module)
     
    but otherwise I have not had any other problems with serial communications with the launchpad,

    Yes it does work. The wiki needs to be finished. If you use the g2231 or the g2452 Energia automatically defines Serial as a TimerSerial object. The jumpers need to be set the default settings when using software serial. Also note that on the g2231 running at 1MHz we automatically limit the speed to a max of 4800. Currently there is no provision for using TimerSerial on the g2553.

    this is one of the threads for the issue, and I know there are more....

    if you are unsure on how to apply the patch, many of us here are able to assist you in applying it.

    The Energia project seems to have a lot of potential for those who want an Arduino environment. I got it sort of
    working on Ubuntu 11.04. It still seems to need some work. I did get it to compile some of the sample programs
    and then run with the Serial Monitor. * I have my Launchpad connected to an FTDI serial usb device hence the ttyUSB0 *

    Here it is with the 'TimerSerialExample':

    Hi Jay,
     
    Sorry to have let this lament for so long, but as far as I'm concerned, the MSPhere project is dead. I had some unfortunate life events pull me away from mcu work, and I've since lost interest in this project. Not to mention, there have been several other projects that attempt the same thing and pull it off much better than MSPhere... friendly_launchpad and EasyMSP come to mind, as does a neat little project porting the Arduino IDE to a LaunchPad compatible form: Energia. Hope this helps!
