Espruino Web IDE. The Web IDE is the preferred way to program Espruino. It's got a syntax-highlighted editor as well as support for dynamically loading modules and for upgrading Espruino's Firmware. You might want to check out other ways of programming Espruino devices.ESPRUINO WEB IDE

Futaba S.Bus System. The S.Bus System is a way of controlling RC servo Motors more accurately using serial data. Normally servo motors use PWM - you can only have one servo motor per signal wire, and accuracy is usually around 1 in 200.. S.Bus servos accept an 11 bit signal (so theoretically are accurate to 1 in 2048) and you can normally have 16 servos per signal wire (each servo needs CCS811 DIGITAL AIR QUALITY SENSOR CCS811 Digital Air Quality Sensor.

Espruino Web IDE loading USING WEB BLUETOOTH WITH ESPRUINO Using Web Bluetooth with Espruino. Web Bluetooth allows a website to connect directly to Bluetooth LE devices. We've also made the UART.js Library to provide a consistent API for accessing Bluetooth and Serial/USB devices from the web.. Note: Web Bluetooth currently works on Windows, Mac OS, Android, Chromebook, Linux and iOS (with this app). To work, Web Bluetooth needs to be run from a SMARTIBOT - ESPRUINO Smartibot. The world’s first Artificial Intelligence enabled cardboard robot that you build yourself. Smartibot works with your smartphone, meaning you can use your mobile as a remote control, or by attaching it to your robot, as it’s brain. SIMPLE FINITE STATE MACHINE Simple Finite State Machine APPLICATION. Module for building and operating simple finite state machines (FSM) for Espruino program control. States can be added as needed and each may define enter, signal, and exit operations.. MODULE REFERENCESERIAL BOOTLOADER
Using STM32's Serial Bootloader. All STM32 ARM chips contain a hard-coded bootloader that allows them to be programmed via USART1. Note: Espruino boards have a USB implementation of the STM32 bootloader protocol built in. Do not follow these instructions unless you want to overwrite the bootloader. BLUETOOTH LE AND NODE-RED WITH MQTT Drag an mqtt input node and a debug output node onto the page, and connect them together. Double-click on the mqtt node, and: Make sure Server says localhost:1883 (you'll need to add a new server the first time you use Node-RED) Make sure Topic says /ble/# - # OPEN WEATHER MAP EXAMPLE Example: Download Current Weather Data ⇠. This example just downloads the current weather condition of a given location ID. You only have to fill in your network ID, Network Password and your open Weather Map API Key. This example was tested with ESP32 and should also work with any other Espruino with network connection (wifi). WEBSOCKETS - ESPRUINO WebSockets. This is a Websocket implementation on Espruino - it lets you: Control your Espruino from the cloud without needing to know its IP (When used as a client) TOTAL AVAILABLE RAM SIZE ON ESP32 AND THE MEANING OF `ESP Since ESP32 has 328 KiB of data RAM, the theoretical maximum DRAM heap for Espruino is 328 KiB.

DRIVER ISSUE(WIN 10): STM32 VIRTUAL COMPORT IN FS MODE Driver worked well in Win 7 until I updated to Win 10. I didn't do a clean install of Windows 10, just an upgrade from 7 to 10. Plugged in a fresh Pico and saw the red light flash. I opened up the web IDE tried the normal way to connect and it said Connect failed. I tried a restart but same thing. So I checked Device manager and noticed: Toggle navigation Espruino* Get Espruino
