Udemy – Web Service Clients on Raspberry Pi Pico W(C++) 2024-4

Web Service Clients course on Raspberry Pi Pico W (C++). In this course, we will examine how to code with C/C++ language to convert a Pico-W to a web service client. We look at two basic libraries for handling the HTTP protocol: LWIP HTTP App and coreHTTP. coreHTTP requires the use of the FreeRTOS core and LWIP sockets. This library gives us a lot of flexibility and allows us to connect to HTTPS web services with wolfSSL. RESTful web services, which we will focus on in this course, respond with JSON data. This course teaches how to analyze this data using two optional libraries coreJSON and tiny-JSON. Some of the web service data returns XML, and two other libraries are considered to handle this data.

This course uses STDIO to output most web services. Two examples use a pre-built Pico-W display board, the PIMORONI Galactic Unicorn. An example uses a TFT screen that needs to be wired to a pico-w. Optionally you can modify these examples to generate STDIO or use alternative hardware. This course assumes that you have knowledge of C++ programming. Although each example describes functionality, this course will not discuss C++ syntax. The FreeRTOS kernel is used to support concurrent tasks and enable POSIX sockets. This course assumes a basic understanding of the FreeRTOS core. I have another course on FreeRTOS kernel for Raspberry Pi Pico that covers this topic. This course assumes you can compile and run C++ code on the Pico using the Raspberry Pi SDK. My other course “Introduction to C Development Environment for Raspberry Pi Pico” teaches these skills. 6. To build and understand these web service clients, a web service test environment using Python is used. A little knowledge of Python would be helpful.
