In this thread, Bob Robertson asked how I made the flowchart that I posted. The answer is a little program that reads pseudocode with a particular syntax and automatically converts it into flowcharts.

I like it because you can very quickly make fairly nice looking diagrams without fooling around with a drawing program. As a bonus, the pseudocode syntax more or less forces you to use good structured programming practices as you're designing your logic.

As an example, here's the pseudocode that made the flowchart in the other thread:

START Start
  Initialize everything
  REPEAT
    IF Got an incoming message?\Yes\No
      Process it and add response (if any?) to response message queue
      ENDIF
    IF Time since last send\> 250 msec\< 250 msec
      IF Anything in queue?\Yes\No
        Send next response and remove it from the queue
        Restart transmit timer
        ENDIF
      ENDIF
    FOREVER

If you want to play with the program, you can download it, along with enough documentation to get started, here.
