It isn't so simple, Charlie. The Linux code tempSensor.c don't run on NetBSD, I tried it. I reed the Datasheet (www-s.ti..com/sc/ds/tmp124.pdf) but says nothing about programming code (at least about C). So, I'm trying to create my own program based on tspld.c (v1.9) of NetBSD 4.0 release, I can compile but I cannot run it. It's shows: segmentation fault.

/* Enable chip select */
GPIO_SET(PFDDR, 0x4);
/* Send read command */
SSP_SET(SSPDR, 0x8000);
}
But, when I run it, it show this messages:

Andres,
If you can't run NetBSD 4.0, and you don't want to back-port the
changes to NetBSD 3.1, the only remaining option would be user-space
access to the sensor.
Earlier I gave you a pointer to the linux user-space program that
would read the temperature for you. Perhaps you should pursue getting
that to compile & run? Between the info on the sensor data sheet, the
linux user-space code example, and the netBSD 4.0 kernel code driver
example, you should have enough info to write a netBSD user space program.
