July 29 - Day 4 – Coding an RP2040 Weather Node

Webinar Information
Start Date: Jul 29, 2021 - 06:00 PM UTC

The RP2040 is not equipped with an on-chip data radio of any kind. So, we will take advantage of our newly enabled UART and use it to add XBee data radio capability to our RP2040 hardware. In today’s lecture we will use the XBee data radio to glean data from my home-brewed backyard weather station. The data that will be received by the XBee data radio will flow into the RP2040 UART we enabled earlier. We will write a routine to process the incoming weather data and display it on the TFT display that is attached to one of the RP2040’s SPI portal.
