Re: [Gumstix-users] robostix/gumstix communication

[Blyskun A. M C. AFIT/E. <ALE...@af...>]

Dave,
  	I'm trying to conduct an easy test of this by connecting COM1
hyperterminal to the GUMSTIX pins.  The jumpers are in place on the
UARTS pins as you have specified.  I'm sure I have my COM1 connected
properly (it is through a RS232/TTL level converter however). =20
	But, my PWM channels aren't working at all.  Was this a proper
way to test?

thanks=20

The same jumper as is used when programming the robostix from the
gumstix will connect the STUART port on the gumstix with the UART0
port on the robostix.

You don't NEED to program the robostix, it jsut happens to use the
exact same hardware lines, so the same jumper works for both
situations.
