Btw,
for you, is it better using threads to do blocking Reads or however simulate
them?
I think using ReadNow is a good solution.
Thanks again,
Antonio

Hi All,
I need a way to make a blocking Read from internal sensors in TinyOS. I'm
using Telosb Tmote-sky.
My friend found a way to simulate blocking Read and I would like to know
your opinion about it.
I wire my software to ReadNow<uint16_t> interface and Resource interface
from Msp430InternalVoltageC;
In the boot of the software I call Resource.request();
When a Timer fires, if Resource.request is granted, I call ReadNow.read();
So, I make a while on a bool value:
while (!exit)
atomic exit = !wait;
where wait = TRUE, exit = FALSE;
The readDone is so structured:
async event void ReadNow.readDone(error_t result, uint16_t data) {
if (result == SUCCESS) {
reading = data;
wait = FALSE;
}
}
This software works fine: when it exits from the while above, reading value
is correct.
Now my question is: the software works fine luckily or my friend found a
good alternative to the blocking Read that doesn't exist in TinyOS?
Thanks a lot,
Antonio
