With lenny rc1 digitemp outputs no measurement from 'DS2438 Temperature,
A/D Battery Monior' -device even it finds it. Normal temperature sensors
are working fine. Tested multiple ways with Formating and no formating.
I fixed the bug by downgrading digitemp to etch.
The etch version is 3.3.2, right? If the changelog is right, the only
thing changed between 3.3.2 and 3.5.0 regarding the ds2438 sensor is the
output. And diff-ing between the sources seem to confirm it.
Yes 3.3.2 vs 3.5.0
So, what happens if you pass the -A switch to digitemp? (this would show
the raw adc values) Does the output change sensibly between the two
versions?
(this should allow us to decide if the bug you reported touches just the
output or if it's something deeper)
With 3.5.0:
Dec 06 19:56:33 Sensor 6 VDD: -1.00 AD: -1.00 C: 22.25
With 3.3.2:
Dec 06 19:24:36 Sensor 6 VDD: 4.74 AD: 1.54 C: 22.34
I'm sorry but I don't own any ds2438 sensor, so perhaps we have to do some
trials to guess the cause of your bug.
This is ok.
