A lot of work has gone into optimization. The good news is Teensy (generally speaking) has much more efficient libraries. Part of Arduino's slowness reputation comes from the library code.
But ultimately it just saves your code to text files and runs the same gcc compiler used by pretty much all the other environments. the Java-based IDE can "feel" quite bloated on slower computers, because the Java runtime consumes a lot of memory. That's why I almost always use "external editor" in Arduino's File > Preferences, and then edit the code using vim.Īrduino does have a reputation for slow & bloated code. Perhaps different editing software helps you to write different code. Of course the editor experience is vastly different. When you call Serial1.write(buffer, size), you're using the exact same hardware serial library built with the same same gcc compiler, regardless of which programming environment. But there too, nearly all the different tools use the exact same set of libraries. For libraries you use, how the library author(s) wrote the library matters. What matters is how you actually write your code. Some expensive commercial software like IAR & Keil have their own compilers, so they actually do generate different output for the same C / C++ source code, but they're not really very different from gcc. The Arduino IDE is uses the same gcc toolchain as every other free software package. I've heard that Arduino IDE tends to generate rather fat, bloaty code.
ī) Makefiles - Again use any Editor you wish to use to generate your project and use/modify the makefile example that comes with Teensyduino.Ĭ) Visual Studio, with some plug in like Visual Micro.ĭ) I often use Sublime Text with stuff that then calls off to Arduino buildīut again this all boils down to what your goals are, and potentially what if any IDE you like.
So for example your sketch folder can have files with a. c extension and are compiled by the c compiler. cpp extension, which are compiled with the C PLUS PLUS compiler. For example look in the Teensy Core directories and you will find some files with the.
That is do you wish to do bare metal and do everything from scratch? Or do you simply want to do some stuff in C versus C++?Ī) Arduino IDE - is simply a wrapper on GCC compiler. WinAVR is only valid for AVR based boards like the Teensy 2.Īgain no idea of what it is you are wanting to do. Best is always in the eye of the beholder.
