Hi David, Is there any example code of using GPIO?
Thanks!

So no, you can't control that without unplugging the battery. Why don't you drive a pin high from the microcontroller to power your external resistors? Or, if the current consumption is greater than the MSP430 can supply, use a GPIO-toggled FET switch to supply current to your resistors. -David On Thu, 18 Jan 2007 18:00:11 -0600 "yicheng" <[EMAIL PROTECTED]> wrote: > Hi, > > > > I have some resistors attached to the Analog VCC output >of my Tmote Sky.
