| # W55RP20-S2E README | ||
|
|
||
| > The W55RP20 is a System-in-Package (SiP) developed by WIZnet, integrating Raspberry Pi's RP2040 microcontroller, WIZnet's W5500 Ethernet controller, and 2MB of Flash memory into a single chip. | ||
| This repository contains firmware that implements Serial to Ethernet using the W55RP20. | ||
|
|
||
| These sections will provide how to configure development environment to develop and modify W55RP20-S2E. | ||

| ## Development environment configuration | ||
|
|
||
| To develop and modify W55RP20-S2E, the development environment must be configured so that RP2040 can be used. | ||
|
|
||
| W55RP20-S2E was developed by configuring the development environment for **Windows**, When configuring the development environment, refer to the '**9.2. Building on MS Windows**' section of '**Getting started with Raspberry Pi Pico**' document below to configure the development environment. | ||
|
|
||
| - [**Getting started with Raspberry Pi Pico**][link-getting_started_with_raspberry_pi_pico] | ||
|
|
||
| If you want development environments other than the development environment for Windows, note that you can find other ways to configure development environment in **'Chapter 9. Building on other platforms'** section of the document above. | ||
