Zoltan Hudak / Mbed OS WebTimer

A remote timer, equipped with a scheduling Web interface, controls a "DigitalOut".

Dependencies:   Timezone NTPClient

WebTimer

The WebTimer is an Mbed device enabling to remotely control a DigitalOut. It has a "calendar-like" user interface to edit the schedule - a table you can click on (or tap on a touch-screen device).
The program was ported to Mbed from the Tuxgraphics site. Thank you Guido for sharing!

  • When starting, it will print it's IP address over the USB serial link to the terminal screen. However, you can set a different static IP address if you modify the code in the main.cpp.
  • To connect to the WebTimer, type the IP address into the web browser edit box and hit ENTER.
  • When a cell is green then the timer keeps it's output ON during that period of time. If a cell is not green it means the output is OFF.
  • To select or deselect multiple cells you can click (keep down the button) and move the mouse over more cells.
  • The smallest time interval on this 24h timer is 15minutes.
  • To save the changes type in the password and hit ENTER or click on the Save button.
  • The default password is "secret". But you can change it by editing the source code in main.cpp.

# Blinky Mbed OS example

The example project is part of the [Arm Mbed OS Official Examples](https://os.mbed.com/code/) and is the [getting started example for Mbed OS](https://os.mbed.com/docs/mbed-os/v5.14/quick-start/index.html). It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/).

You can build the project with all supported [Mbed OS build tools](https://os.mbed.com/docs/mbed-os/latest/tools/index.html). However, this example project specifically refers to the command-line interface tool [Arm Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
(Note: To see a rendered example you can import into the Arm Online Compiler, please see our [import quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)

1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).

1. Clone this repository on your system, and change the current directory to where the project was cloned:

    ```bash
    $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
    ```

    Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:

    ```bash
    $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
    ```


## Application functionality

The `main()` function is the single thread in the application. It toggles the state of a digital output connected to an LED on the board.

## Building and running

1. Connect a USB cable between the USB port on the board and the host computer.
2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
    ```bash
    $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
    ```
The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.

Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.

Depending on the target, you can build the example project with the `GCC_ARM`, `ARM` or `IAR` toolchain. After installing Arm Mbed CLI, run the command below to determine which toolchain supports your target:

```bash
$ mbed compile -S
```

## Expected output
The LED on your target turns on and off every 500 milliseconds.


## Troubleshooting
If you have problems, you can review the [documentation](https://os.mbed.com/docs/latest/tutorials/debugging.html) for suggestions on what could be wrong and how to fix it.
