hello janos
hope u remember this thread from a long time ago. starting work on it again.
is this correct (with reference to ur last email)? is it what u meant? pls
see the commented areas.
-------------------------------------------------
module HplRF230P
{
provides
{
interface GpioCapture as IRQ;
interface Init as PlatformInit;
//interface McuPowerOverride;
}
uses
{
interface HplAtm128Interrupt as Interrupt;
interface GeneralIO as PortIRQ;
interface HplAtm128Timer<uint16_t> as Timer;
}
}
implementation
{
command error_t PlatformInit.init()
{
call PortIRQ.makeInput();
call PortIRQ.clr();
return SUCCESS;
}
async event void Interrupt.fired() {
uint16_t time = call Timer.get();
signal IRQ.captured(time);
}
async command error_t IRQ.captureRisingEdge()
{
call Interrupt.edge(TRUE);
call Interrupt.enable();
return SUCCESS;
}
async command error_t IRQ.captureFallingEdge()
{
// falling edge comes when the IRQ_STATUS register of the RF230 is
read
return FAIL;
}
async command void IRQ.disable()
{
call Interrupt.disable();
}
async event void Timer.overflow() {}
/*async command mcu_power_t lowestState()
{
if enabled // how to do this?
return ATM128_POWER_IDLE
else // how to do this?
return ATM128_POWER_DOWN
}*/
}
-------------------------------------------------
thanks
