It doesn't play very nice with programs that draw to the active display buffer, as it uses double buffering by default. Text alignment works in mine, doesn't in Win32, so games/xalthorn/gemocide.txt's tips screen looks better on mine. It's more accurate than the Win32 one in some respects, and less accurate than others. You'll need a fairly beefy computer to run this. The graphics pane is 640x512, so everything should look as good as it can. Uses HTML5 canvas, but has a super special (terrible) low-level graphics engine with all the commands written from scratch, so there's no horrible HTML5 antialiased lines ruining your nice demos. Tokeniser, parser, lexer, compiler and runtime all written from the ground up.

function ArrayBufferView.I've reimplemented the PS2 Yabasic environment in JavaScript.function ArrayBufferView.find(function).function ArrayBufferView.filter(function, thisArg).function ArrayBufferView.fill(value, start, end).If you want to access arrays of differing types of data Uint24Array (Espruino-specific - not standard JS).This is the built-in JavaScript class that is the prototype for: function Array.splice(index, howMany, elements.function Array.reduce(callback, initialValue).function Array.indexOf(value, startIndex).function Array.includes(value, startIndex).function Array.forEach(function, thisArg).function Array.filter(function, thisArg).function Array.every(function, thisArg).This is the built-in JavaScript class for arrays.Īrrays can be defined with, new Array(), or new Array(length) Methods and Fields In order to be able to write to the pin again you need to disable Note: On nRF52 chips (used in Puck.js, Pixl.js, MDBT42Q) setWatch disables the GPIO Watch two pins with the same number - eg A0 and B0. Note: The STM32 chip (used in the Espruino Board and Pico) cannot Note: if you didn't call pinMode beforehand then this function will reset pin's state to "input" When doing this, interrupts will happen on both edges and there will be no debouncing.

However, if the callback is a native function void (bool state) then you canĪdd irq:true to options, which will cause the function to be called from within the IRQ. Time that it happened, and the function supplied to setWatch is executed only from the main Internally, an interrupt writes the time of the pin's state change into a queue with the exact This will only be called on the falling edge of the pulse, but will be able to measure the width of the pulse because e.lastTime is the time of the rising edge.

If you want code to be executed right after loading (for instance to initialiseĭevices connected to Espruino), add a function called onInit, or add a initĮvent handler to E with E.on('init', function() ). When Espruino powers on, it will resume from where it was when you typed save(). Instance a=1 save() a=2 will save 'a' as 2. This command only executes when the Interpreter returns to the Idle state - for The ones from before the save, and the ones from after - which may cause you problems.įor more information about this and other options for saving, please see Note: If you set up intervals/etc in onInit() and you have already called onInitīefore running save(), when Espruino resumes there will be two copies of your intervals. To see what will get saved you can call dump(). The state will then be loaded automaticallyĮvery time Espruino powers on or is hard-reset.

Save the state of the interpreter into flash (including the results of calling With no mode argument ( pinMode(pin)), auto as the argument ( pinMode(pin, "auto")), or with the 3rd 'automatic'Īrgument set to true ( pinMode(pin, "output", true)). If you want digitalRead/etc to set the pin mode automatically after you have called pinMode, simply call it again Note: digitalRead/ digitalWrite/etc set the pin mode automatically unless pinMode has been called first. Sending a logical 1 leaves the pin open circuit
