Hi all,

My onboard temp sensor seems to be dead (fixed at room temp). I dont think I am skilled enough with a soldering iron to replace it (per FAQ)

However, I am willing to try Ben's IC2 Fan Controller, which has a temp sensor.

Is there a way to for Hijack to read from Ben's temp sensor and output it into Vital Signs (or another menu entry)?

It would be great to monitor the temp again especially with summer coming around soon.

Thanks!

We really ought to work out a simple rewiring job -- route the necessary GPIO pin from the SA1100 over to the temp chip so that it can be "reset" back to normal operation (under s/w control) whenever it glitches out like that.

Anyone know of an unused GPIO pin inside this sucker?

I have a feeling I remember Hugo saying they were pretty full up on IO. Can't find where though.

If he designs stuff anything like us, he'll use every last CPU/micro feature available. We never seem to have enough IO.

Can it be reset in hardware anyway? I thought it was stuffed for life once configured the wrong way or whatever happened.

Yep, I can never work out why we didn't use an i2c temp sensor originally. I suspect both myself and Patrick were totally blind to the LM77 when we went looking - the 1-wire unit is a pain in the ass, frankly, and more expensive too.

That and lower value I2C pullups so we didn't have to run the bus so slow. The perils of not owning a scope, I suppose (we didn't get one until after the mk2 ISTR).
