  1. Here is my entry for the November 2010 Project of the Month Contest, an MSP430G2xxx based tea timer! I love tea, and thought this contest was an excellent reason to actually get off of my lazy behind and put this together. Below is my blog post on it, modified slightly to show the pictures and code here rather than just link to them as on my blog. Blog post is available here: http://blog.suspended-chord.info/?c=27 Below this point is the post: ------------------------------------------------------ Hello all, I am an avid tea drinker. As such, I make many cups of various kind

  3. if it can be made perfect, there will be no need to calibrate. from the datasheet the MSP430G2231 has a typical accuracy of plus/minus 3%, at idea case it's plus/minus 0.5%. if u can keep constant voltage and constant temperature, it will be more accurate. even crystals have some drifts and for accuracy u can match capacitors or even oven control them (for temperature). no, but u can make it happen by entering various LPM modes, for more power saving (LPM3) you will need to use VLO (or 32Khz crystal) as the DCO is also shut down. if u really want to showcase this, u can . inside the wh

    IRC

    I think a IRC is deffinitly missing! an irc would speed up discussions and is perfect for quick simple questions! I think 43oh is going to be a real grate cumunity portal in some time. I think its the right time for expanding it a bit! The forum has nearly 100 members ok only 20-30 of them are really active but it's not a bad ratio and some people are still reading the forum without registration. i beleave that new users will come here every day. TI has still problems to supply all the launchpads to people who ordered them. If you extend the headline of the page with IRC

    Need a favicon?

    Do you want/need a favicon.ico for the site? I was making one for my blog, and thought I'd whip one up for you using your theme colors. Use it or trash it; you won't hurt my feelings. It took all of a couple of minutes. 16x16px, looks like this: 43oh-favicon.ico.zip -Doc

    Keeping Track of Time?

    yes, this is basic digital io. just don't mix it up with adc input. you check whether a pin is HI or LOW (meaning zero volts) by looking at the P1IN or P2IN registers (port 1 and port 2). and since it's digital there is only 0 or 1 (low / hi) so to detect a trigger from the master (assuming a low-hi-low pulse) you would. assuming your input pin is P1.1 while (1) { if (PIIN &= BIT1) { // detect a rising edge (hi) while (P1IN &= BIT1); // wait for falling edge (low) // do your led display pin toggling here }//if }//while have not tried the above, i think

  8. u will need five of those, one for each digit and one for the master controller.

    To answer the part that I do know: No, you cannot set a voltage other than Vcc on an output pin. What you are looking for is a Digital to Analog Converter (DAC) function, which the MSP430G2231/2211 do not have. The LaunchPad does have a nice ADC (Analog to Digital Converter), but that is obviously the opposite direction. I believe there are other MSP430 models with DAC functions, but I'm not sure if they are compatible with the LaunchPad. Others here are more familiar with the rest of the MSP430 line and may be able to help.
