# [Stm32 Eth](https://github.com/offa/stm32-eth)
[](https://github.com/offa/stm32-eth/actions)
[](https://github.com/offa/stm32-eth/releases)
[](LICENSE)
Ethernet connectivity for *Stm32F4* Boards using W5100 Ethernet controller.
## • Requirements
- [**CMake**](http://www.cmake.org/)
- [**CppUTest**](https://github.com/cpputest/cpputest) – *(Optional)*
- [**GNU ARM Embedded Toolchain**](https://developer.arm.com/open-source/gnu-toolchain/gnu-rm) (*arm-none-eabi-gcc*)
## • Testing
Build and execute Unit Tests:
```
mkdir build && cd build
cmake ..
make
make unittest
```
Executing tests using CTest: `make test` or `ctest`. For `unittest` it's possible to switch verbosity by CMake option.
## • Integration Test
Integration Test for *Stm32F4* are enabled by the `INTEGRATIONTEST` option. The target `stm32-eth-it` is available as *ELF* (default) and *HEX*.
## • Flashing (OpenOCD)
Both *ELF*- and *HEX*-files can be flashed using [***OpenOCD***](http://openocd.org/):
```sh
$ openocd -f stm32f4discovery.cfg
```
```sh
$ telnet localhost 4444
> reset halt
> flash write_image erase
> reset run
```
## • Wiring & Pin Assignment
#### W5100 Wiring
Connect ***Reset*** and ***3.3 V*** with **4.7 kΩ Resistor**.
