I learnt something new reading up on HEX- and INI-files and it would be of great help with a method like this.

I will try your examples and see if I can be of any help.

I will try to clarify.

Is it not the order of the parameters given in the constructor that matters when creating a new object?

If the sensor constructor looks like this:

KellerNanolevel(byte modbusAddress,
              Stream* stream,
              int8_t powerPin, //Power pin of sensor.

It is very basic but I guess every journey must start somewhere…

The first code snippet is from the example code in the menu a la carte example. I’ve edited my first post just to clarify that.

The second one is from the Modular sensor library.

I have used the Yosemitech and Keller librarys as a template and tried to make it as basic as possible.

When checking the example code for the modbus sensors i get…[Read more]

We could maybe use 50 cards but I probably won’t make it right the first time and then I have 50 cards to recycle.

I used the board file to make some shields but this is something another level. I will have a look around at the University for some expertise in the matter.

Maybe it is simpler for us to use something like a f…[Read more]

Does anyone have any suggestions or hints how to do it with the Mayfly board?

I saw somewhere that Shannon Hicks soldered some parts of the board herself. I guess I can try to order the board and see…[Read more]

I prefer this kind of bug though…

It was actually very instructive to go through the libraries and trying to learn how they work. It was driving me nuts when it was working with the deep debug flag but it finally made sense.

In the modified ThingsSpeak sketch the constructor was the problem.

I tried to modify the thingspeak example but then everything got messed up and the pins scramled. I’ll try with another computer and see if I can find the bugs in my code. Probably something very simple.

-I’m using platformio on VSCode. (I’m really not comfortable using it but these kind of problems is good for actually learning hands on. There is a lot of strange things in there that I don’t understand and I wish I could find a really good tutorial how to work with it.)

Tried the “data_saving”-example as is and the logger restarts even if I keep the enable pin at -1. Doesn’t make a difference if I detach everything from the Mayfly and I tried both different usb-cables and FTDI-cable.

The “thingspeak” example works if I don’t add any Yosemitech libraries/sensors in the code. I wonder if I’m…[Read more]

Did you have any ESD-problems with that foam and those cases? I’ve tried to use some fake pelican boxes (made of PE plastic I belive) as enclosures for electronics and had huge problems; as soon as I came close to the box the electronics went crazy.

Would really be a time saver to buy exactly what I need on a PCB instead of building it out of Arduino modules or designing the entire board myself.
