Raspberry Pico Adventures

In this post we will see how to access a REST API with the Raspberry Pi Pico W, using the SDK C/C++ and MicroPython. An example of a call to a RESP API, using Postman Basically, a REST API is uses an HTTP method (like GET and POST) to access and manipulate "resources".

We will now take a look at TCP communication. There are client and server examples at pico-examples, let's see if we can understand what is done.

As the next step in my studies, I implemented a SNTP client. I also connected an alphanumeric display, so there was something to see in the photo.

As I mentioned before, I decided to start my study of the Pi Picos's C/C++ SDK function for WiFi communication implementing an SNTP client . This just an exercise, as it is also available in both the lwIP library and the SDK examples. So we start by looking how it is done in the SDK example (code here ). The Pico example output 

 The Raspbery Pi Pico W  adds to the Pico the ability to do network communication using WiFi (and, maybe, Bluetooth in the future). For starters, I will focus on C/C++ programming. The first steps in learning about the way WiFi is implemented and how to use it are the SDK documentation and the official examples . For those who want an easier and faster path, there is also MicroPython support. My first Pico W!

While the Pico W was announced months ago, only now it is available in Brazil. This is a quick review of what it brings. A Pi Cow (photo by @RaspberryPi)
