I'm a total electronic newbie that is gathering experience while tinkering. If the UART is burned on this node, then so but it, far from the end of the world. I would still like to know how to go about getting my goal accomplished. Also, I do not have an oscilloscope or logic Analyzer, but if this is the suggested hardware to get this done, then I'll get my hands on one (one way or another). William, please provide me with you suggestions on the recommended methods for getting these two to communicate. Keep in mind that I do have a logic level convert from sparkfun in my possession. Thanks for any help you can provide, it is definitely greatly appreciated.
