Hi everybody, I am not too much familiar with HW stuff and a little more than newbi on SW. I would like to use this ESP32C3 supermini board. For the pinout I found some different versions on the web and I wonder which one is the real one? My second question is: I want to use just 3 simple digital output signals to drive stepper motors, 5 digital inputs for switches and pulse buttons and the ...
Many times people ask questions about how to fix their LCDs that don't display or displays wrong/random stuff. The following information, when supplied with your thread, will get your problem solved the quickest way. Fixing these problems ends up being mostly a frustrating experience unless the following are provided upfront without any "BUT"s. I believe several other helpers here would agree ...
I made an awesome program the other day, and I wanted to upload it to my Arduino. After clicking the upload button, some mean dude named avr came along and stopped me, saying: avrdude: stk500_get...
Having more than one version of a library installed can be a serious problem. Best practice is to uninstall the whole library and make sure all files are removed from the sketch/libraries folder, before you install the version you intend to use. The multiple library found warning usually shows up when there is a compilation error, but it is not unusual for more than 1 library to be found, and ...
15 The Arduino "language" is nothing more than a set of C++ functions and classes. It does not mandate any particular C++ standard. The standard is dictated purely by the compiler that the core you are using happens to support (and is configured to use through command line flags). Different cores use different compilers.
I wander what is the best option for formatting strings in Arduino for output. I mean what's a preferable way in the point of view of performance, memory usage – things like that. I see, people us...
Notice also that in C++ (which Arduino is), you don't need to use typedef for structs either, so I've removed that from the struct definition. I'm also using the stdint.h types, which are considered safer and "best practice" for data types, as they specify the exact type size in bits.
