Espruino 1.86

petypen · 10 июл 2016

Коллеги, добрый день.
Гордон выпустил новую версию Espruino.
Новость тут: http://www.espruino.com/Download
Что нового, Гордон описал на форуме:

This one's been a while coming, but it's got a few nice additions/fixes:

E.setBootCode and flash execution
You might have noticed the Save on send option in the Web IDE - this uses E.setBootCode to save your code as-is to Espruino's flash memory. It's then executed straight from read-only memory and any functions you define are kept in flash.

While this actually uses up more flash memory than the normal (compressed) arrangement, it can save you a lot of RAM.

Promises
Espruino now has a 'Promise' library built-in on all but the most constrained platforms - so stuff like this now works:

Код (C++):

new Promise(function(resolve, reject) {
var ok = false;
// do stuff
if (ok) {
resolve("Stuff worked!");
} else {
reject("It broke");
}
}).then(function(result) {
console.log(result); // "Stuff worked!"
}).catch(function(err) {
console.log(err); // Error: "It broke"
});

I know some people like programming like this (to avoid all that nesting) so this may help...

process.on('uncaughtException', ...)
This allows you to catch any exceptions that your code produced but that weren't caught. For instance you might want to log the exceptions to read-only memory for later debugging, or just light up a warning light.

force argument on Serial.setConsole()
For example with USB.setConsole(true), you can make sure that Espruino's console always stays on USB and doesn't get in the way of Serial, regardless of whether USB is subsequently plugged or unplugged.

Fix software PWM glitches
It used to be that whenever you modified software PWM, PWM was stopped and then started again, and this made it 'glitch'. This is now fixed so you can animate software PWM values without any glitches.

E.kickWatchdog()
Espruino's had E.enableWatchdog for a while - which checks that the interpreter is always going around the idle loop, but you can now do E.enableWatchdog(time, false) which means that if your code doesn't call E.kickWatchdog() within the time period the chip will auto-reset.

It's a great way of making sure that your code really is running as expected.

micro:bit improvements

micro:bit's show() function now works well with Graphics

Many nRF51/2 fixes and improvements

Fixing micro:bit compass issues

Other Fixes and Improvements...

Telnet now built into linux builds (use --telnet to enable) - also some Telnet fixes

Finally added .removeListener so you can remove just one listener (for example when using multiple listeners on Serial)

Added require("Flash").getFree() as multiplatform way to find free flash pages

Add the ability to set clock frequencies on STM32F4 chips (like Pico) with E.setClock

Add E.setBootCode to allow JS scripts to be saved without being in RAM ()

Expecting a number or something iterable, got X changed to exception rather than warning (so you now get a stack trace of the error)

Ensure that pinMode/digitalWrite is re-constituted properly by dump() and save() (fix #833)

ESP8266: Some read-only variables moved to flash to save a whole bunch of RAM

GCC 5.3.1 now used for ARM release builds

Fix potential variable corruption issue when copying objects/arrays containing packed ints

ESP8266 printLog memory leak fixed

Added Object.get/setPrototypeOf that are nicer than accessing prot_ directly

Fix memory leak when executing bound function with 'this'

Fix issue when turning a negative Date to a string

Stop eval in a switch statement from confusing parsing

Fix regression in 'mode' argument of SPI.setup (allows custom CC3000 pins to work)

Fix '.on' with long event names

Enable F4Discovery button pull-down. Newer boards don't seem to have one fitted

Unterminated expressions now produce errors

New slow but memory efficient sin and atan for devices with really low memory

Прошивка для Iskra JS теперь тоже базируется на 1v86. Можно обновлять штатным способом, через Settings → Flasher.

Возможно мне не сюда, но кажется именно после перепрошивки у меня код заливается с ошибкой. Раньше (с месяц назад) все заливалось без проблем.

sys · 11 июл 2016

а если вместо P1 указать B10? выдаст ошибку?

Все получилось...Я так понимаю все остальное аналогично? B20, B30..

sys · 12 июл 2016

синонимы не работают .... походу поспешили выложить свежачок

угу... только не B20 B30, а A6 A7 и далее по схеме из вики http://wiki.amperka.ru/_media/js:iskra_jsinout.png

muchmumuu · 12 июл 2016

Шикааарно! Все работает) Спасибо за помощь)

sys · 12 июл 2016

Всегда пожалуйста! я так понимаю, что нам стоит ожидать в ближайшее время исправленной версии прошивки

nailxx · 12 июл 2016

Упс. Поправили в 1v86.1298. Выложили, можно накатывать.
