Hi everyone! I am having a problem interfacing an SHT11 sensor into a Micaz
mote.
>From the SensirionShtLogicP.nc, I got a return FAIL message from these
lines:
error_t waitForResponse() {
call DATA.makeInput();
call DATA.set();
call CLOCK.set();
if (call DATA.get()) {
// the device didn't pull the DATA line low
// the command wasn't received or acknowledged
return FAIL;
}
call CLOCK.clr();
return SUCCESS;
}
Retracing the wiring of the DATA interface, I found from
HalSensirionSht11C.nc that:
SensirionSht11LogicP.DATA -> HplSensirionSht11C.DATA;
Now I'm not sure if I got the right connection for the DATA interface. This
is my revised code of the HplSensirionSht11C:
configuration HplSensirionSht11C {
provides interface Resource[ uint8_t id ];
provides interface GeneralIO as DATA;
provides interface GeneralIO as SCK;
provides interface Interrupt as InterruptDATA;
}
implementation {
components HplAtm128GeneralIOC;
// components new Msp430GpioC() as DATAM;
// components new Msp430GpioC() as SCKM;
// components new Msp430GpioC() as PWRM;
// components new HplAtm128GeneralIOPinP() as DATAM;
// components new HplAtm128GeneralIOPinP() as SCKM;
// components new HplAtm128GeneralIOPinP() as PWRM;
// DATAM -> HplAtm128GeneralIOC.PortE7;
// SCKM -> HplAtm128GeneralIOC.PortC3;
// PWRM -> HplAtm128GeneralIOC.PortC0;
DATA = HplAtm128GeneralIOC.PortE7;
SCK = HplAtm128GeneralIOC.PortC3;
// DATA = DATAM;
// SCK = SCKM;
components HplSensirionSht11P;
HplSensirionSht11P.PWR -> HplAtm128GeneralIOC.PortC0;
HplSensirionSht11P.DATA -> HplAtm128GeneralIOC.PortE7;
HplSensirionSht11P.SCK -> HplAtm128GeneralIOC.PortC3;
...
Can someone help me check if I got the connections right? I revised these
codes from the application that uses Msp430 (telos) instead Atm128 (micaz)
Thank you in advance for those who will help.
