Hi,
I have a problem related to external interrupt.
I have a sensor, which has one interrupt pin. I configured the sensor to
generate an interrupt when some even happens.
For the hardwire wiring, I did two experiments: one is I wired the sensor INT
pin to micaz PE4/INT5; another PE5/INT5.
The following is the tinyos code:
In SensorAppC, I have
SensorC.IO4 -> HplAtm128GeneralIOC.PortE4;
SensorC.SensorINT4-> HplAtm128InterruptC.Int4;
SensorC.IO5 -> HplAtm128GeneralIOC.PortE5;
SensorC.SensorINT5-> HplAtm128InterruptC.Int5;
In SensorC, I have
module SensorC @safe() {
uses {
...
interface HplAtm128Interrupt as SensorINT4;
interface GeneralIO as IO4;
interface HplAtm128Interrupt as SensorINT5;
interface GeneralIO as IO5;
...
event void Boot.booted() {
call IO4.makeInput();
call IO4.set();
call SensorINT4.disable();
call SensorINT4.clear();
call SensorINT4.edge(TRUE);
call SensorINT4.enable();
call IO5.makeInput();
call IO5.set();
call SensorINT5.disable();
call SensorINT5.clear();
call SensorINT5.edge(TRUE);
call SensorINT5.enable();
...
My problem is never SensorINT4.fired trigger, but SensorINT5.fired always
trigger.
Can any expert give some comments?
