If you're using TinyOS 2.x, you can use the GeneralIO interface. GIO1 maps to the MSP's P2.1 pin, so the configuration bits would be like: components HplMsp430GeneralIOC, new Msp430GpioC() as GIO1, YourC; YourC.GIO1 -> GIO1.GeneralIO; GIO1 -> HplMsp430GeneralIOC.Port21; Using the GeneralIO interface in YourC would use bits like: uses interface GeneralIO as GIO1; GIO1.makeOutput(); GIO1.clear(); GIO1.set(); > my question is... is possible settint the output voltage of > TOSH_SET_GIO1_PIN(); instruction? now i've vcc/2 about 1,2 volt... > is possible setting that output to vcc? As I understand it, the MSP430 uses totem pole output drivers. A logic 1 set to an pin configured for digital output should generate a voltage very close to Vcc. Perhaps the pin really isn't set as a digital output. A floating input might behave as you describe. _______________________________________________ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
