  1. There are also some new sites; MSP430G2402; http://focus.ti.com/docs/prod/folders/p ... g2402.html MSP430G2452; http://focus.ti.com/docs/prod/folders/p ... g2402.html but the datasheet are missing
  2. Yes, I think someone mentions somewhere that 9600 is the max speed suported by the Launchpad The accelerometer is a freescale MMA7361, (free sample) and is connected as follows; Pin 5 Vss -> Gnd 6 Vdd -> Vcc 10 g-select -> Vcc 7 Sleep -> Vcc 13 Self test -> Vcc 2 Xout -> ADC channel 3 Yout-> ADC channel
  3. OK! i'll add the other QFN packages sometime in the future and hopefully the 20 pin MSP430 as well
  4. I checked for other DIP packages on EAGLE (Microchip, Analog Devices, etc) and they all are the same. I was looking this datasheet; http://focus.ti.com/lit/ml/mpdi002c/mpdi002c.pdf there you can see the 0,4" width at the tip of the pins and the 0,3" width near the CI body. I found this other as well; http://www.ece.tamu.edu/~jinyilee/ecen4 ... torial.pdf, in which you can read (Pg. 17): "For standard ICs (op-amps, logic, etc) the distance of spacing between the columns of pins is 300 mil and between rows of pins it is 100 mil." I'll do some more research to find out how it should be don
  5. Here it is, if anyone found problems with the symbols please tell me in order to correct them TI_MSP430G_v1.rar
  6. I have a library with G2X01, G2X11, G2X21,G2X31 devices. I copied and changed the symbols and packages from TI`s library so they look very similar. I haven't finish it yet, there are a couple of devices with QFN packages missing, but I guess most of us use DIP, so if you like I'II upload the file here if someone want to take it a look
  7. I was expecting a UART for RS232 comunication

    has anyone seen this? :shock: http://link.ti.com/ninjaneer/en/
  9. That's nice!!! Freescale and Microchip have similar tools. It's great to see TI making things easier for us.
  10. Sure! these are some of the photos I used in the video;
  11. Thanks for the feedback guys!!! That's rigth. If you see the processing code you will notice a blue zombie that's not implemented, I had some problems identifing the three of them. The blue one had ADC values between the red and the gray zombie so I finally decided to remove it making easier the identification of the orher two. Although the project need some work I like the idea of interact with the screen with cheap sensor as LDR or photodiodes. While I was finishing this I saw on MAKE blog an article about a little board with a mcu and a light sensor that can be reprogrammed puting the
  12. Killing Zombies with the Launchpad Well, this is my entry for the November 2010 Project of the Month Contest. It is very simple and far less usefull than the others projects. The truth is that I wasn't participating until I saw the Chronos .So i had to come up with something easy and fast to develop. I was plaiyng arround with some leds and photodiodes in front of my pc monitor and I thought that cold be interesting to interact with the screen with the photodiodes or some other ligth sensor. that idea eventually ended up being a shooting game. I wasn't too sure what to shoot at but then i
  13. YES! I'm sorry, I should have said something about that, that was only for the photo. The correct connection is the other way round

  15. It seems that you can, I used some homemade flux and a solder with a very thin tip, this is what it looks like the solder side, by the way I prove it and it works fine, I was afraid of cold solder joints
  16. thanks simpleavr!!! It is soldered on the other side of the board...You are rigth about the LED's legs, those might work. Perhaps I'll try to use them with the other Launchpad I have.
  17. In case somebody want to use that Launchpad's feature I made the connector with some 26/6 staples
  18. I personally prefer the ADC10, Its has more stable readings than the SD16.
  19. yes indeed. i found that later...after destroying one :oops: assuming that more pressure was better after seeing the paper about the proyect i was talking about I realised that the way to do it was with a capacitor to store the voltage that the piezo generates, take a sample and discharge it. Perhaps in the future if I can get some piezos i'll try it out again
  20. Great work! I tried a similar thing in the past, but I was more interesting in using the piezos as pressure sensors instead of picking up sound (well, technically with sound it also sense the wave pressure...). I attend a bioengineering congress in wich some guys show how they hook up a bunch of these on an insole (i'm not sure if i'm using the right term here) in order to measure the foot preasure for gait analisys. It is a cheaper solution compared with comercial ones. At the end i had some problems with the signal, those things work great with sound but don't have a good behaviour with co
  21. thanks!! well the accelerometer it's just one possibility, you could hook up any other device to both ADC channels to control the snake, in fact...that could be a nice challenge: make new,differents and funny ways to play!!!
  22. Thanks for the feedback!!! i'm trying to upload the video again with better resolution
  23. I made this little project and wanted to share it. The code is mostly from "Half Duplex Software UART on the LaunchPad" by NJC, I just added the ADC parts I needed. The Processing application send first a "X" and the LP answer with the value from one of the axes, then send a "Y" and you get the value from the other axis. After that the soft update the snake position and repeat the process. In order to start the game you have to click on the START button (pretty obvious), you lose if the snake touchs any of the sides, also the length and speed increase as you eat the little boxes. The codes
