Topic outline

  • This week you will learn how to establish communication between two or more PCBs that you made. The recommended route this year is to use one of the wireless capable XIAO boards, such as the XIAO ESP32C or XIAO nRF52840.

      • You are a(n) Student
      • You are a(n) Teacher

      Follow the steps below to complete your assignment.

      • Explore the WiFi capabilities of the XIAO ESP32C3 board.
      • Plug it into one of the boards you produced earlier.
      • Program the XIAO board to spawn an Access Point and create a simple REST API.
      • The REST API should have endpoints for controlling output device(s) of your board as well as reading input.
      • Document as you go and publish content on a page on your documentation website.

      In this video the basics of serial communication via TX/RX lines of the Arduino is shown.

    • Use this wiki page to learn the basics of the XIAO ESP32C3.

    • This is one of many resources that explains what is the REpresentational State Transfer (REST) Application Programming Interface (API).

    • Here you can find the code examples we discussed in the lecture.
