Hi, Couldn't you use the Gpio interfaces in something like the example below?
In the configuration: components new Msp430GpioC(); components HplMsp430GeneralIOC; Msp430GpioC.HplGeneralIO -> HplMsp430GeneralIOC.Port62; MyAppC.Pin -> Msp430GpioC; Then, in the module use the GeneralIO interface: interface GeneralIO as Pin; Then you should be able to to set the pin to high/low with the following calls: call Pin.set(); call Pin.clr(); Cheers, Urs Michael Schippling wrote: > Lets keep this on the help list in case someone actually knows something... > > I suspect that you can't do that because the memory spaces are not > the same.
