-# Blinky Mbed OS example
+# Semestralka na VPS
 
-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/latest/quick-start/index.html). It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/).
+Tato hra je najsamlepsejsia na celom svete.
+Iba si treba matchnut baudrate a moze sa gamesit.
 
-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 tools, [Arm Mbed CLI 1](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli) and [Mbed CLI 2](https://github.com/ARMmbed/mbed-tools#installation).
-
-(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).)
-
-## Mbed OS build tools
-
-### Mbed CLI 2
-Starting with version 6.5, Mbed OS uses Mbed CLI 2. It uses Ninja as a build system, and CMake to generate the build environment and manage the build process in a compiler-independent manner. If you are working with Mbed OS version prior to 6.5 then check the section [Mbed CLI 1](#mbed-cli-1).
-1. [Install Mbed CLI 2](https://os.mbed.com/docs/mbed-os/latest/build-tools/install-or-upgrade.html).
-1. From the command-line, import the example: `mbed-tools import mbed-os-example-blinky`
-1. Change the current directory to where the project was imported.
-
-### Mbed CLI 1
-1. [Install Mbed CLI 1](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
-1. From the command-line, import the example: `mbed import mbed-os-example-blinky`
-1. Change the current directory to where the project was imported.
-
-## 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.
-
-**Note**: This example requires a target with RTOS support, i.e. one with `rtos` declared in `supported_application_profiles` in `targets/targets.json` in [mbed-os](https://github.com/ARMmbed/mbed-os). For non-RTOS targets (usually with small memory sizes), please use [mbed-os-example-blinky-baremetal](https://github.com/ARMmbed/mbed-os-example-blinky-baremetal) instead.
-
-## Building and running
-
-1. Connect a USB cable between the USB port on the board and the host computer.
-1. Run the following command to build the example project and program the microcontroller flash memory:
-
-    * Mbed CLI 2
-
-    ```bash
-    $ mbed-tools compile -m <TARGET> -t <TOOLCHAIN> --flash
-    ```
-
-    * Mbed CLI 1
-
-    ```bash
-    $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
-    ```
-
-Your PC may take a few minutes to compile your code.
-
-The binary is located at:
-* **Mbed CLI 2** - `./cmake_build/<TARGET>/develop/<TOOLCHAIN>/mbed-os-example-blinky.bin`
-* **Mbed CLI 1** - `./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.
-
-## 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.
