Reef Angel Forum

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?

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. ??

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

5V

Can you tell me the value of R29?

4.7K

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.

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.

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.

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.

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

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.

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.
