	Why not add the source file type .s (lower case 's') to Visual Micro. It is a great way to expose someone to assembly, minus real time debugging and great for those die hards like me. See attached text file (rename to delayMS.s and add to your AVR project). The .ino must contain the following: extern "C" { void delayMS(uint16_t); }

	Great idea. I will add as a new file option. Thanks very much

	I looked at this and started to build in the facility. I hit an issue where by your example is specific to the avr architecture so it would be appreciated if we can also do same for SAM and SAMD if that makes sense. Otherwise the menu item to create .s files will have to appear and disappear based on the currently selected hardware. If you have time to give other examples that will be appreciated.

	Yes, I should have specified I was doing this on AVR (Arduino UNO). I do not have SAMD board to test with. The feature would be nice but not necessary, since one can manually add the *.s file to an AVR project.

	Okay thanks. What might be useful is to provide an empty .s file more easily for visual studio users. Atmel studio already has the facility so I guess you are using that. Thanks again.

	For those who would enjoy a little Arduino UNO assembly: Create a Visual Studio/Visual Micro project named BlinkyAssembly. Replace the BlinkyAssembly.ino create by Visual Micro with the attached BlinkyAssembly.ino. Place the delayMS.s file into the project folder and add it to your project ("Add Existing"). Compile and download. The function void delayMS(uint16_t) is a blocking function that spins its wheel until it has consumed the delay period passed in. This is provided only to demonstrate using assembly, and has not been exhaustively test for delay accuracy... but should be close Rich
