  1. AllJoyn.js Feature/Project

  2. What is AllJoyn.js? • AllJoyn + Javascript • ECMAScript (Javascript) language interpreter and compiler for small IoT devices • Integrate AllJoyn onboarding and config, notifications, control panel, events/actions • Provide for OTA installation of script files • Enable remote debugging over existing AllJoyn physical transports. (No JTAG, No USB) • Native code support • Easily integrate native code (C/C++) with ES into compiled executable for target device • High-level programming constructs • Portable • Built-in regular expression engine • Built-in Unicode support • Hardware support • Language extensions or new functions included for interaction with hardware interfaces typically found on microcontrollers (GPIO, PWM, I2C, SPI, ADC, DAC) • Compact footprint • 128KB RAM, 500KB Flash AllJoyn.js ECMAScript Engine AllJoyn Core +Services Hardware Abstraction Layer ADC PWM DAC UART I2S I2C SPI GPIO

  3. Why is it important? It’s all about Time-To-Market pb=IO.pin("C6", IO.PullDown);pb.trigger(IO.FallingEdge, function(){ AJ.notification(AJ.notification.INFO, "Button Pushed!").emit(100); }); varcp = AJ.controlPanel();var c1 = cp.containerWidget(cp.VERTICAL, cp.HORIZONTAL);var bright = c1.propertyWidget(cp.SLIDER, 50, "Brightness:");bright.range = { min: 0, max: 100, increment: 2, units: "percent" };var brightness = 0.5;var led = IO.pin(1, IO.Output);bright.onValueChanged = function (val) {led.pwm(1 - (bright.value / 100), 200);} • Leverage large Javascript developer community for IOT applications • Maker community driving a lot of innovation and major shift in product development for IOT • Simplify IOT application development • Embedded C development experience not required • Simplified AllJoyn setup & access to service frameworks • Simplified access to hardware (GPIO, SPI, I2C, PWM, ADC, DAC) • Device drivers can be written in C or ES and called from ES • Portable • User code can be moved to different devices that support AllJoyn.js • No recompilation of ES code • Will require native code (if used) to be re-compiled for new target • Will require pin mapping tables to be updated Code for sending AJ Notification on button press Code for exposing Control Panel slider to change LED brightness
