Yay!

Those temperature shouldn’t be a problem.  If I remember right, one of our first box iterations ended up acting like a little greenhouse and turning into an oven in the summer.

Could it be the amp-to-volt board that’s the problem instead of the sensor?  Do you have a second one you could test against?

The install guide for windows 10 is here:  https://www.ftdichip.com/Support/Documents/InstallGuides/AN_396%20FTDI%20Drivers%20Installation%20Guide%20for%20Windows%2010.pdf  Look at section 3.3 starting on page 9.

Remember that you need to be a computer administrator.  If you’re using a school/work laptop that you don’t have admin privileges fo…[Read more]

You absolutely must have administrative privileges to install drivers on Windows.  If you don’t, it might be the reason they failed to install with the Arduino program.

The “setup executable” linked in the comment column is probably the easiest way to install the drivers.  There is also a link to an installation guide there.  I’ve added sc…[Read more]

The drivers are available here:  https://www.ftdichip.com/Drivers/VCP.htm

Could it possibly be a problem with the temperature inside your logger box rather than the water temperature?  Maybe Shannon can pipe in and confirm, but I remember that we used to have issues like this when we were using black boxes with clear lids facing summer sun.  I think the Mayfly’s ADC starts acting up when it gets too hot.  Are you re…[Read more]

Also, with PlatformIO version 5 you can now specify the owner along with the library name in the lib_deps section so you’re sure you get the right one.

I’m sorry for being late on this.

It’s definitely something with the newest versions of PlatformIO and the very weird part is that for me *sometimes* it works and other times it does.

What I’ve usually ended up doing is putting *everything* into the lib_deps section.

<!–more–>Yeah, so 99.99% of what I’ve said on this thread can be completely disregarded. Obviously the sensor and firmware work just fine and there never was any problem with them.  The biggest problem was my understanding of the problem.

If everything is perfect except the 3m cable, then it’s just the 3m length that is the problem. It’s…[Read more]

You had a working library and code this whole time.

?!?

Well I feel really, really stupid.

What code are you running to get the values?  The results you shared with me based on the code I gave you didn’t have any good values at all.  I thought you didn’t have any working code for communication.

I’m guessing you’ve made one of these:  https://github.com/EnviroDIY/TippingBucketRainCounter

I’ve edited the code that makes it work with ModularSensors, but I haven’t ever built one.  Sorry.

@aufdenkampe?

Does it output good value*S* or one single good value over and over?  If the former, then..I just don’t know how to read this firmware.  If the latter, then, no that’s what I expect.

3m is beyond the maximum expected transmission length for I2C, so, no, it’s not at all strange that it wouldn’t work over that long a distance.  If you need that di…[Read more]

That’s the firmware I’ve been looking at.

You know what, I don’t think this firmware even functional.  It won’t ever take a sample.  Well, it should sample 1 time at the beginning, and then never again.  Ugh.  I wasted a lot of time parsing the I2C bits of the firmware and writing code for you and didn’t ever question that that sampling part of…[Read more]

You don’t need the whole firmware; actually I’d prefer not to get the firmware, but instead to get a short breakdown of the required I2C registers and commands.  All I would be doing with the full firmware is trying to decode what the registers are anyway.

I’m sorry; I’ve spent a lot of time reading through that firmware and if there’s something you have to do to get it to start taking readings, I don’t know what it is.  So either I’m just not understanding the firmware or that’s not the firmware that’s actually on your device.  I don’t think there’s any other way I can help you if you cannot get a…[Read more]

All of the Atlas sensors do have a built in sleep command that you can use for low power without needing the isolator. You should be able to add ‘RTD.send_cmd(“SLEEP”);’ and ‘EC.send_cmd(“SLEEP”);’ to your system sleep function.

I’m sorry I’m late to the game on this one.

Shannon said more clearly what I would have said. But re-reading, I remember that the Atlas sensors are special. You can’t cut the power to the Atlas circuits while they’re connected to the I2C bus of the Mayfly or your program will crash. The Atlas circuits have the I2C lines pulled up to the voltage…[Read more]

So it is there and responding, but there’s something wrong with my code because it’s not giving data.  Do you know if the firmware on your device *is* that code on github?  Otherwise, I don’t see in that code what I have to do to get it to start reporting values.
