Related to #4186. Some notable changes: - The term 'Error' now strictly refers to native Error objects defined in the ECMA standard, which are ordinary objects. All other uses of 'error' or 'error reference' where the term refers to a thrown value is now called 'exception'. - Simplified the naming scheme of many String API functions. These functions will now also take an 'encoding' argument to specify the desired encoding in which to operate. - Removed the substring-copy-to-buffer functions. These functions behaved awkwardly, as they use character index to specify the start/end positions, and were mostly used incorrectly with byte offsets instead. The functionality can still be replicated with other functions if necessary. - String-to-buffer functions will no longer fail if the buffer is not sufficiently large, the string will instead be cropped. - Fixed the usage of the '_sz' prefix in many API functions. The term 'sz' means zero-terminated string in hungarian notation, this was used incorrectly in many cases. - Renamed most of the public API functions to have shorter, more on-point names, rather than the often too long descriptive names. Functions are now also grouped by the type of value they operate on, where this makes sense. JerryScript-DCO-1.0-Signed-off-by: Dániel Bátyai dbatyai@inf.u-szeged.hu
JerryScript with mbed OS 5
TL;DR? jump straight to quickstart
Introduction
This directory contains the necessary code to build JerryScript for devices capable of running mbed OS 5. It has been tested with the following boards so far:
- Nordic Semiconductor NRF52 Development Kit
- NXP Freedom K64F
- STM NUCLEO F401RE
- Silicon Labs EFM32 Giant Gecko
Features
Peripheral Drivers
Peripheral Drivers are intended as a 1-to-1 mapping to mbed C++ APIs, with a few differences (due to differences between JavaScript and C++ like lack of operator overloading).
- DigitalOut
- InterruptIn
- I2C
- setInterval and setTimeout using mbed-event
Dependencies
mbed CLI
mbed CLI is used as the build tool for mbed OS 5. You can find out how to install it in the official documentation.
arm-none-eabi-gcc
arm-none-eabi-gcc is the only currently tested compiler for jerryscript on mbed, and instructions for building can be found as part of the mbed-cli installation instructions above.
make
make is used to automate the process of fetching dependencies, and making sure that mbed-cli is called with the correct arguments.
nodejs
npm is used to install the dependencies in the local node_modules folder.
gulp
gulp is used to automate tasks, like cloning repositories or generate source files. If you create an own project, for more info see mbed-js-gulp.
(optional) jshint
jshint is used to statically check your JavaScript code, as part of the build process. This ensures that pins you are using in your code are available on your chosen target platform.
Quick Start
Once you have all of your dependencies installed, you can build the example project as follows:
git clone https://github.com/ARMmbed/mbed-js-example
cd mbed-js-example
npm install
gulp --target=YOUR_TARGET_NAME
The produced file (in build/out/YOUR_TARGET_NAME) can then be uploaded to your board, and will run when you press reset.
