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.

hudakz 0:f78e57015038 2 # Blinky Mbed OS example
hudakz 0:f78e57015038 3
hudakz 0:f78e57015038 4 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/).
hudakz 0:f78e57015038 5
hudakz 0:f78e57015038 6 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).
hudakz 0:f78e57015038 7 (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).)
hudakz 0:f78e57015038 8
hudakz 0:f78e57015038 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
hudakz 0:f78e57015038 10
hudakz 0:f78e57015038 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
hudakz 0:f78e57015038 12
hudakz 0:f78e57015038 13 ```bash
hudakz 0:f78e57015038 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
hudakz 0:f78e57015038 15 ```
hudakz 0:f78e57015038 16
hudakz 0:f78e57015038 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
hudakz 0:f78e57015038 18
hudakz 0:f78e57015038 19 ```bash
hudakz 0:f78e57015038 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
hudakz 0:f78e57015038 21 ```

hudakz 0:f78e57015038 24 ## Application functionality
hudakz 0:f78e57015038 25
hudakz 0:f78e57015038 26 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.

hudakz 0:f78e57015038 28 ## Building and running
hudakz 0:f78e57015038 29
hudakz 0:f78e57015038 30 1. Connect a USB cable between the USB port on the board and the host computer.
hudakz 0:f78e57015038 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
hudakz 0:f78e57015038 32 ```bash
hudakz 0:f78e57015038 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
hudakz 0:f78e57015038 34 ```
hudakz 0:f78e57015038 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
hudakz 0:f78e57015038 36
hudakz 0:f78e57015038 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
hudakz 0:f78e57015038 38
hudakz 0:f78e57015038 39 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:
hudakz 0:f78e57015038 40
hudakz 0:f78e57015038 41 ```bash
hudakz 0:f78e57015038 42 $ mbed compile -S
hudakz 0:f78e57015038 43 ```
hudakz 0:f78e57015038 44
hudakz 0:f78e57015038 45 ## Expected output
hudakz 0:f78e57015038 46 The LED on your target turns on and off every 500 milliseconds.
