Lpc2000

14K Wow.  And I thought the 1M rate I'm getting with the Signum JetJTAG was slow.  I can't imagine doing tons of debuging at 14K.

  We've found that you can't drive the signals on a PC parallel port at 
  more than 4kHz (this is in GPIO/bit bang mode - EPP/ECP is a different 
  tale). Even with this limitation CrossWorks for ARM has a flash download 
  speed of 14Kbytes per second to the LPC21xx.

  >And what would that be?  I thought that a download of the OCD app from the same people who make the hardware should likely work.  I can understand some really limited features, but a 4kHz connection speed? That really surprised me.
