README
## Example of a web server using Pico SDK and lwIP
This example was described in more detail in a blog post: https://krzmaz.github.io/2022-08-15-creating-a-web-server-on-raspberry-pi-pico-w-using-pico-sdk-and-lwip/
In my testing it reached ~20x performance of the MicroPython implementation from point 3.9.1 of https://datasheets.raspberrypi.com/picow/connecting-to-the-internet-with-pico-w.pdf
If you want to test this example with your html files, just add/edit them in the `src/fs` directory and rebuild the project!
---
### Dependencies:
- CMake 3.19+
- ARM GNU toolchain
- [Perl](https://www.perl.org/get.html) (should be already present on *nix systems)
For the first two you can refer to [these instructions](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf#%5B%7B%22num%22%3A39%2C%22gen%22%3A0%7D%2C%7B%22name%22%3A%22XYZ%22%7D%2C115%2C841.89%2Cnull%5D)
---
### One time setup
```bash
cp cmake/credentials.cmake.example cmake/credentials.cmake
#
```
### Building
```bash
./build.sh
```
### Flashing
The built USB Flashing Format file will be located in `build/src/pico_w_webserver.uf2` - just copy it over to the Pico W to flash it!
### SSI
Now the example uses Server Side Includes (SSI) to introduce dynamic data into the HTML responses.
As per documentation:
> SSI-enabled pages must have one of the predefined SSI-enabled file extensions
Which means that no cost should be introduced in non SSI pages
