openplotter-gpio v3.x.x released

[Polonioli]

some cheap bme280 are fake. try another from known source.

With op v2 work very fine, is with op v3 is not work

[holgerw]

ok, so it must be an softwarebug in v3

did you test the signalK-plugin "signalk-raspberry-pi-bme280" to let it read the data from there?
this worked for me in OPv2. i try to use most hardware sensors from signalK directly.

New openplotter-gpio v3.2.24 published. We have added support for pulse sensors and we go from alpha to beta.

There are many things you can do with pulse sensors. This is an example to get RPM from your engine connecting the 'W' terminal or tachometer signal wire (using an optocoupler so as not to fry the Raspberry):

   

You can also get wind speed. This would be the settings for a Davis anemometer. To get linear speed from RPM values you need to provide the radius of the wind sensor:

   

And this would be the settings for a chain counter using a pulse sensor in the windlass. You also need the radius:

   

If you want to reset to 0 the "Revolutions counter" and the "Distance" values you have 2 new "Actions" in openplotter-notifications app to be triggered when you need.

Please test and report as usual.

OpenPlotter GPIO app for v3 is released.

- Seatalk1 feature is done and tested but is not published yet because we are waiting for the next signal K server update. This new version will fix a critical bug in Seatalk1: https://github.com/SignalK/signalk-server/pull/1455

- GPIO pulses feature still needs some work.

- GPIO 1W feature is published and tested.

- GPIO digital feature is published and tested. On this v3 we have added GPIO outputs!

As usual I will not give any instruction or clue so we can also check usability. Install from OpenPlotter Settings as usual. Test and report please, thanks.

Hi Sailoog, I’m quite new to oppenplotter and struggling with usability. I installed Seatalk via an octucupler connected to Gpio 4. But the Gpio setup windows states at themfoot: Gpio read not running instead of Gpio service enabled. 

Am I missing a step and should I enable the service somewhere?

[Sailoog]

"Gpio read" service is used only by GPIOs defined in digital, 1W and pulse tabs. GPIOs defined in seatal1 tab use the pigpiod service. You are right, that message could be confusing.

after setting your seatalk1 GPIO press "Check system" in the openplotter menu to get more info about running services. If it does not work check your wiring and settings.
