PineDio Stack BL604 @PINE64 is a #RISCV board that’s packed with #IoT features: Touchscreen, LoRa, WiFi, BLE, GPS and more.

In this presentation we’ll talk about the porting of Apache #NuttX RTOS to PineDio Stack, how we simplified the developer onboarding, and our plans to support #LoRaWAN and LVGL Apps in #ZigLang.

What if we could drag-and-drop Apache #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 Apache NuttX Sensor Apps.

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