Hi Neil,
Thanks for sharing your experience. It’s unclear to me the intent of the Switched 3V3 jumper on the Mayfly I2C port; it appears that it cannot be used in the Switched position with peripherals that pull up the I2C lines (which most seem to do) because the Wire library locks up.
I’m also doing some testing with power consumption and hope…[Read more]

If I understand correctly, you cannot set the Mayfly’s I2C Grove port jumper to “switched 3V3” if you’re using it to communicate with a connected I2C device. According to the datasheets and other documentation I’ve read, most (all?) I2C devices have pullup resistors on their SDA and SCL lines, which these two posts suggest that having the Mayfly…[Read more]

Thanks @srgdamiano — and thanks so much for announcing the release here on the forum and sharing links to the release notes on GitHub!
Until somewhat recently, I didn’t fully grasp the connection between a ModularSensors GitHub release number and the version number in the PlatformIO library registry. To clarify for others who may be new to these…[Read more]

How can I specify floating-point precision when using MS_DBG()? For example:
float myFloat = 0.0001875; MS_DBG(myFloat);
prints:
0.00

Matt Barney replied to the topic Add Sensor button not working on MonitorMyWatershed in the forum Mayfly Data Logger 3 weeks, 6 days ago
I was curious whether opening Developer Tools (in Chrome) would show any insight to this problem. To my surprise, the Add Sensor button worked while I had DT open! One time I had to refresh the page while DT was open in order to get the Add Sensor dialog to display. Might be a workaround until the problem gets fixed.

Matt Barney started the topic Duplicate ModularSensors libraries in PIO in the forum Mayfly Data Logger 1 month, 3 weeks ago
When you include
lib_deps = EnviroDIY_ModularSensors
in platformio.ini, PlatformIO consults its registry to install the library and its dependencies. However, I just noticed that there are two in the registry: one under envirodiy and one under srgdamia1. Presumably envirodiy is the correct one? While it is possible to specify a library…[Read more]

Matt Barney replied to the topic Board Basics in the forum Mayfly Data Logger 2 months, 2 weeks ago
I can recommend the Mayfly Hardware page, along with the Features and Jumper Settings links found there.
As far as reading and writing to the various pins in code, I’d suggest the Mayfly Software page, and particularly the LearnEnviroDIY link there, which is a series of detailed tutorials to get you started.
Good luck,
Matt

Matt Barney replied to the topic DFRobot Gravity KIT0139 Depth Sensor – Routine Interference? in the forum Environmental Sensors 3 months, 2 weeks ago
It would be interesting to see if the anomalies in sync with periods when the Mayfly’s battery voltage is peaking, i.e., during maximum solar input.
It sounds like you have the sensor on a separate circuit from the Mayfly. If that’s the case, should the grounds tied together between these two circuits? I’m not an electrical engineer, so I don’t…[Read more]

Thank you, Sara, for the additional tips for working around this PIO issue. I haven’t gotten a response yet on their github issues page, so need to post it on their community forum for others who are experiencing the same issue.

Matt Barney replied to the topic PlatformIO not downloading all ModularSensors dependencies in the forum Mayfly Data Logger 3 months, 3 weeks ago
Update: This looks to me like a PIO issue. Reverting to earlier versions of PlatformIO IDE, it works; i.e., it downloads all ModularSensors’ dependencies as expected, and my project compiles successfully. This is using a ‘minimal’ platformio.ini file that looks like this:
[env:mayfly] platform = atmelavr board = mayfly framework = arduino lib_deps…
