Introduction Sometimes you may want to connect 2 microcontrollers to a computer. In this case, you have to manually select a different serial port to upload code on each microcontroller because, by default, PlatformIO handles port selection automatically. Or you may want to change the baud rate (upload speed) in PlatformIO.This tutorial will walk you through the process of selecting ports and changing the baud rate in PlatformIO. Port Selection in PlatformIO Here are ...
