Current Software and Reliability Issues in Project Curacao

Current Software and Reliability Issues in Project Curacao

As we get closer to system deployment (March 2014), I am running more system level tests.  The first of these (the week of November 17-24) revealed the following problems that need to be addressed: – The DHT22 sensor is returning more errors […]

Software Status on Project Curacao (11/25/13)

As of today, the current state of the software in Project Curacao is as follows: – Arduino Battery Watchdog:  The watchdog is reading and reporting data back to the main software in the Pi via a serial link through level […]

    Just got my WeatherPiArduino and WeatherRack. I hope to set up a Citizens Weather Observer Program station. Soldering in the DS3231 blocks the data and clock pins for the I2C. I installed it along with an AM2302 in a proto shield instead. The Arduino with instruments overloads my Raspberry Pi USB bus locking up the keyboard and mouse. The Arduino required an external power supply. I am having problems with the Sketch. Libraries time.h and elapsedMillis.h were missing. Defines are for interrupts on pins 18 and 2. Connections are on pins 2 and 3 in your wiring diagram.

    I would like to know where you put your code after designing a RasPiConnect screen. Where is the command file called from to get the button responses?
    I see you use a command file, where does the commands come from? Does the RasConnect send them to the command file?

    Thank you

    how do you integrate your command.txt in your MouseAir program into RasPiConnect Local.py file. Where do the command = f.read() come from?

    I see that the SunAIRPlus is out of stock on Amazon, any idea when it may be back in stock. I’m trying to build a solar project and want the monitoring capabilities of the plus.

    Thanks,
    Geoff

      Geoff,

      There are 7 more heading to Amazon and they should be there on or about March 28th. We got caught with a big order from back east. We have ordered more and the next batch of 100 should be here in about 3 weeks.

      The 7 coming up to Amazon are the new Grove connector units. They are 100% compatible and they now include the Grove Adaptor to Male Headers cable.

      Best,

    I previously contacted you about a switch bounce problem with my rain tipper. I had another problem of rain indication when there was no rain. After months of experimentation I found that the phantom rain was being caused by USB power noise. It appeared on every computer I tried, but was minimal on a laptop. Searching the internet I found this post: http://andybrown.me.uk/2015/07/24/usb-filtering/. I modified a USB adapter for my Pi 3 using his circuit. For a few cents worth of parts the phantom rain went away. Now I was able to see a reliable 3 triggers per tip which I corrected in software. This noise was probably affecting wind speed as well. Now I can calibrate my rain gauge against a tube gauge and recalibrate my anemometer.

    My station software is written in Python and runs on Windows, Linux and Mac. It post a local web page, ftps a web page to a web server, and telnets the data to the National Weather Service via the Citizens Weather Observer Program. With the addition of an AM2302 for humidity, the quality control analysis of my data by CWOP has shown it to be accurate and reliable except for rainfall.

      Excellent find. I have repeated this in the forums for others.
