Temp sensor problems

[Bryan]

Roberto:

Having an issue with the temp sensor set-up. When added to the board they do not show up on the display. only one can be read at a time. if I reboot, the unit freezes, display is black until I unplug one of them and then it returns to life. Will only operate with one sensor

Also noted that even when just using one sensor, no matter what socket I plug it in, it only displays on T1

Here is my ReefFeatures.h

It will always be T1 no matter which port.
It's a digital sensor and will be assigned T1, T2 and T3 according to the laser incribed address it was assigned at manufacturing following their order of release. Each sensor has a unique address.
But, the way you are describing, it seems you have a bad probe.
Do you get readings from both of sensors if they are plugged individually?

[Bryan]

Roberto:

Probes are fine, each one plugged in individually and they work (have to reboot though), plug in two and reboot the screen goes black, pull out a sensor and the screen jumps to life and everything is fine. ??

[rimai]

Are you running your board on 3.3V or 5V?

[Bryan]

5V

[rimai]

Can you tell me the value of R29?

[Bryan]

4.7K

[rimai]

Are you extending the cable?
4k7 should be good enough.
I used even 10K before with no problems.
But in your case, it seems not to be the case.
Would you be able to change it to a smaller one?
Any value above 1K should be good.

[Bryan]

Hi Roberto:

Cable not extended, tried 2K and no luck same thing, wonder if it is a code issue. Do you have a default PDE that I should use to test.

[rimai]

Very weird.
I wonder if it has anything to do with the libraries on AVR Studio.
Try loading up this hex file.
It's compiled with avr-gcc through Arduino IDE.

[Bryan]

Hi Roberto:

Afraid you may be right <sigh>. Do you mind posting the sketch you used. I think I might know what the problem is in AVRStudio, but want to make sure I have the right sketch code first.

[rimai]

I actually used the standard libraries, but here is the sketch.

[Bryan]

I think it might be one of the compiler optimization flags I am using in AVRStudio that could be causing the problem. They both use AVR-GCC so can't see why it would not work other than my addition of additional flags.

[Bryan]

Yup, that was what it was, one of the optimization flags I was using, just not sure which one though, will be a process of elimination. Used the standard flags that Arduino uses and it worked, albeit a larger hex size.
