I'm not giving up on this. I worked on it until the sun came up and still no luck. The only thing I have found is that when the jumpers are removed and I hook my logic analyzer up to the emulator side of the board I get good serial messages.

Oh! Should I have the external oscillator installed?

I just rechecked my connections, I have my shifter hooked up as you indicate. The shifter I am using is this: http://www.sparkfun.com/commerce/product_info.php?products_id=133 . I just retried the launchpad's comport and am getting nothing as well.

Thanks for all the friendly help! Its rare to get that on the internet now. I loaded NJC's code, but cant seem to make it echo anything. I am using a terminal (realterm) and a usb to serial cable through a TTL lever shifter to simulate the RFID reader. My terminal is sending one ASCII character (letter A) at 9600 baud 8N1 but I get nothing back. I confirmed the integrity of what I send with a Saleae logic analyzer and can find nothing wrong. It also seems that that the TX pin goes high after the reset button is pushed and stays high until a logic low is present on the RX pin. :?: I removed the jumpers, what the bleep am I doing wrong? @NJC, thanks for the effort you put into your blog. I'm learning a lot from it, I just need to start from the beginning. @cde, Thanks for the hint about where I should put my code. I kinda thought that would be the place to put it, I just wasn't sure. Thanks for being patient with my noobness! -Bill

I'll be more than happy to share the code. I had the Parallax RFID reader but I killed it somehow. This project will use the RFID 20 from Sparkfun, should be the same code with a higher baud. NJC, The code posted on your blog looks a little over my head even though I haven't tried to play with it yet. I will probably have a ton of dumb questions! Thanks for the help all! -Bill

I'm new to microcontrollers and programming, but even newer to the MSP430. I have a Launch pad and a project involving an RFID reader. I have no clue how to receive a serial string and parse them with the 430. I have an Mbed and can do it with that, but its a little expensive for this project. Any advice would be greatly appreciated -Bill
