  1. I try my best to break it down nicely. The post I specifically linked to builds off of other posts, so if you feel a bit lost check out the older ones. :-) And about asking questions, there no dumb question (unless its something which can be found using Googles "I'm feeling lucky"). I check out these forums often, and will do my best to explain any parts of my code which might not be clear. Let the questions flow. I'm writing up the last post for the oscilloscope project now, but after that's done I will be making a page with a list of past posts since I know how much of a pain it can

  2. Oh, the RFID-20 outputs at 9600 Kbps, just like NJ's uart is set up for. As a quick test, just hookup the RFID-20 to the rx pin of the launchpad (remove the rxd jumper as well), and load NJ's code, and you would get the rfid's tag id echo'd to your computer. Your code should just go into the if received section. if (hasReceived) // If the device has recieved a value { hasReceived = false; // Clear the flag TXByte = RXByte; // Load the recieved byte into the byte to be transmitted Transmit();

  3. Bill, I've built a couple of projects which parse serial input (based on NJC's code). They should be easy to adapt: http://blog.hodgepig.org/2010/09/09/573/ http://blog.hodgepig.org/2010/09/10/575/ It's the RFID reader is SPI, then my SPI Explorer should get you most of the way there.

  4. Hey Bill, I have a blog which has some beginner guides. More pertinent, I have a post where I explain how to implement a half-duplex software UART. You can use this as a foundation for the rest of your project, once you have the processor receiving data you can start working processing it. http://www.msp430launchpad.com/2010/08/half-duplex-software-uart-on-launchpad.html Hope that helps, NJC

  5. &^%# IT! They always get me with free shipping! In for another (free) EZ430-F2013 and three (more) LaunchPads. Why? Because I think they lost my last backorder and, if not, can you really have too many LaunchPads? (Seriously, I'll probably give them away to friends if I get both orders.) BTW: You can only use the EZFREE2013 code once. I tried. Whaaat? I was curious. -Doc
