So, I notice that in plugging in my Nucleo F401RE, that it pops open a file explorer window with the MBED.HTM file and DETAILS.TXT showing in the window. An error occurred while uploading the sketch This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. Please ensure the device is correctly connected. Global variables use 1044 bytes (1%) of dynamic memory, leaving 97260 bytes for local variables. ![]() I followed them, got the sketch to compile, but I get the error:Īrduino: 1.8.5 (Windows 10), Board: "Nucleo-64, Nucleo F401RE, Mass Storage, Generic Serial, None, Smallest (-Os default)" Archiving built core (caching) in: C:\Users\bjfur\AppData\Local\Temp\arduino_cache_286105\core\core_STM32_stm32_Nucleo_64_pnum_NUCLEO_F401RE,upload_method_MassStorage,xserial_generic,usb_none,opt_osstd_d724efeaa56f34424fff8f97231228d4.a Sketch uses 11064 bytes (2%) of program storage space. They are not C.Thank you for the clear, complete instructions. So if you structure a sketch like this: fooĪnd use this #include directive in your sketch: #include "src/bar.h"Īlmost as if the IDE is completely ignoring the C source files.Īrduino sketches are converted to C++ before being compiled. Support for compilation of sketch subfolders was added one or two IDE versions before 1.6.10 and was originally not limited to the src folder but a lot of problems were reported by people who had stored separate programs in subfolders of their sketch that caused compilation errors so this feature was restricted to the src subfolder only. In this project, we will be using a small pushbutton switch to control an LED. ![]() A switch is a electrical component that completes a circuit when pushed and breaks the circuit when released. So my question is what is the correct/current way of organizing the above project so that it can be compiled/linked using the IDE? I am using IDE version 1.8.5 which I believe is either the latest version, or close too it.įrom Arduino IDE 1.6.10 onward the Arduino IDE compiles all source files in the src subfolder of the sketch and recursively through all folders under the src folder. Now it’s time to talk switches and how they can be incorporated into Arduino projects. All these methods seem to depend on IDE version, and I couldn't distill what was the correct way vs a hack or work-around. I've even tried manually adding source files via the "sketch/add file" option which makes the files visible in the IDE but does not solve the linking problems. Some versions only acknowledge headers in subfolders, others work if you put everything in a "src" folder (I've also seen mention of a "utility" folder), some people suggest modifying environment variables, etc. In trying to resolve this I've discovered that apparently the handling of subfolders by the IDE seems to be all over the place. Almost as if the IDE is completely ignoring the C source files. However, when the IDE tries to link, all references to implementations (c source files) in the subfolders generate "undefined reference" errors. ![]() The sketch file includes the headers via quoted include directives (rather than the lib alternative with angled brackets). I've divided up the project like this to keep things clean. See the instructions for building the code. Active development of the Arduino software is hosted by GitHub. Refer to the Getting Started page for Installation instructions. This software can be used with any Arduino board. I have a sketch with multiple source files and folders arranged like so. The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board.
