Visual Programming with Zig and NuttX Sensors

Video Presentation

PDF Slides with Transcript

What if we could drag-and-drop NuttX Sensors to create IoT Apps? In this presentation we’ll explore Blockly, the web-based toolkit for Visual Programming, and how we might customise Blockly to create NuttX Sensor Apps.

We’ll also discuss the Zig Programming Language, and why Blockly will generate NuttX Sensor Apps as Zig programs.

Pine64’s PineDio Stack BL604 is a RISC-V board that’s packed with IoT features: Touchscreen, LoRa, WiFi, BLE, GPS and more. In this presentation we’ll talk about the porting of NuttX to PineDio Stack, how we simplified the developer onboarding, and our plans to support LoRaWAN and LVGL Apps in Zig.
