Hello, I'm new to the software development with the Arduino IDE. I currently have a project where I use an Arduino Nano ESP32 and the Arduino IDE 2.3.2. What are some general best practices and code structuring for Arduino? I'm doing PLC development since 10 years now. And general question: I …

[image] cdcdcd: I'd like to rather restructure my .ino file, or split the different functions up into seperate files which I then just call in my main .ino file. Is that possible? Sure it is! The compiler is a C++ one, so you can either use "#include" to incorporate external file (located in …

[image] cdcdcd: Can I call setup and loop in other files too? You can, but you shouldn't. If you do you will have endlessly recursive code... Until it crashes.

While you can have multiple .ino files and regular C++ source files in the root sketch directory, I'd recommend having just the one single .ino, which has the same name as the directory (that's what makes it a valid sketch); and then regular C++ source and headers under a tree in the src subdirector…

normally i push often used piece of code in a function, or if this piece do something similar like LCD output, or time renew. so loop() contain only names of functions and it is mostly clear what sketch do. and when function ends, every not static variable will disappear and free memory. extremely …

I want to do like a little sequence: Scan wifi networks > connect to the network thats implemented into the project > connect to the mqtt broker thats implemented in the project And after that sequence if everything is fine I just want to subscribe to a topic, deserialize json .. do some input/out…

[image] cdcdcd: which is a lot to scroll through. Have you tried collapsing the functions that you don't currently want to see the details of ?

I feel like it's not visibly enough collapsed.. or spaced. Currently trying to print my mac address without a wifi connection

[image] cdcdcd: But I'm currently already at 280 lines of code in the .ino file, which is a lot to scroll through.. thats why I wanted to just call those functions in my .ino file after another. As already mentioned, use of proper .h / .cpp files provides useful modularity. See My Port #5 in …

[image] cdcdcd: Currently trying to print my mac address without a wifi connection Take your pick: #include "Arduino.h" #include "WiFi.h" void setup() { Serial.begin(115200); delay(2000); // Method 1 uint8_t mac[6]; WiFi.macAddress(mac); Serial.printf("MAC Address: %0.2X:%0.2X:%0.2X:…

[image] cdcdcd: I feel like it's not visibly enough collapsed.. or spaced. I can't get what you're saying here, please provide an example. If you "fold" a function (Using Ctrl Shift ') it shows only the definition and collapses the content. E.g. the function: void showDateKWH() { lcd.setC…
