Visual Studio Code for Arduino - OTA Programming

My previous post Visual Studio Code for Arduino Basics left me with just one itch unscratched. I'd kind of come to love over-the-air (OTA) programming. My robotics project (using an ESP8266) communicates over WiFi, the "base station" app was all set up and communications using JSON were working perfectly. If I needed to deploy updated robot code I could do it without the hassle of cables. So, does OTA work out of the box with Visual Studio Code? Yes! And no. I wished there was a simple blog post to explain it, so I've had to write it myself. Without further ado ... Hardware Requirements We're assuming here you're using Arduino hardware that has WiFi. Mine is an ESP8266. Whatever hardware you have, I recommend you go back to the basic Arduino IDE and do some OTA programming from there. Just be sure the process works before you add the complexity of Visual Studio Code to the problem. Networking So that we can send code over OTA we have to know the dev...

Building DateTime for Arduino

Testing. Yup, testing. With this class it can’t be avoided. Actually, even better, instead of seeing testing as a chore, let’s use it to our advantage. We’ll build a suite of tests for the unfinished DateTime class and test it until it works. The goal here is to write all the tests first and run them. Some percentage of them will fail. Then we modify the DateTime class until all tests pass. As we find issues along the way, we add more tests. Get code here: https://github.com/prawnhead/ArduinoDateTime

Visual Studio Code for Arduino Basics

I'm partway through a robots project using Arduino and Processing. While getting into OpenCV I managed to cock-up my Python installation so badly on my Mac that I just trashed the whole machine and started again. Having come back into Arduino and Processing after a long break I decided not to persist with the rudimentary IDEs that each provides. Visual Studio Code time! Software Installation I'm working on a Mac so this wouldn't historically be platform on which to use Visual Studio. But Microsoft is more enlightened these days and Visual Studio Code is available for Windows, Mac and Linux. So I just downloaded and installed it. Done. Arduino and Processing don't have the polished installation process of VS Code. Download, unzip and then copy the .app into /Applications. Having "installed" these, you're still banned from using them so after trying to open each, go to System Preferences > Security & Privacy and "Open Anyway". Visual...
