This is very interesting @neilh20 ! 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.

Sorry for being so vague. 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.
              int8_t powerPin2…

Hi Neil,

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.

Yes, that is true. 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]

I have been thinking about order some Mayfly boards through some PCB assembly service (because the board is not available in Sweden where I live).

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’m not expecting you to fix all my problems, but I’m very grateful for any help I can get. 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.

I totally missed @neilh’s…[Read more]

Finally some progress when I got some help.

In the modified ThingsSpeak sketch the constructor was the problem.
YosemitechY504 y504_1(y504ModbusAddress1, modbusSerial, modbusSensorPower, max485EnablePin, y504NumberReadings); -> did not work
YosemitechY504 y504_2(y504ModbusAddress2, modbusSerial, rs485AdapterPower, modbusSensorPower,…[Read more]

It feels like a memory leak but I can’t see why. 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.

My reply is very hard to read especially when all my spacing got removed. Sorry for that:)

Attaching a .ini didn’t work so here it is:

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages

To answer your questions:

-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.)
-Attached my “platformio.ini”
-I’ve tried both…[Read more]

I’m totally lost. 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]

Wow, I just realized I didn’t really post any real question and still you are helping=)I’m really thankful and impressed by all your effort.

I have ordered a module with automatic flow control from Amazon but I didn’t want to wait for it to arrive so I started with what I had.
The module I have has been working nicely before but this time I…[Read more]

That is fantastic news! It will speed up my preparations for the coming field season. Thanks for all your work!
