Arduino - Development - Modul : Esp32TimeSystem

Download : Esp32TimeSystem Version 01v04

• Das VSCode-Projekt "2604221530_Esp32TimeSystem_01v04.zip" muss nach dem Download zuerst in ein Zielverzeichnis entpackt werden.
• Ein Doppelklick auf die datei "Esp32TimeSystem.code-workspace" öffnet das Projekt in VSCode.
• "Compile" und "Run" flashen und starten das Projekt auf einem angeschlossenen "Esp32UnoBoard" .
