Board Support Package For NodeMCU-ESP32S Boards

Introduction

This board support package (BSP) supports NodeMCU-ESP32S boards. ESP32S boards with 30, 36 and 38 Pins are supported. The BSP is based on ESP32 Xtensa libraries and tool chain. It supports both single core and dual cores available on the board.

Getting Started

§ Install Silicon Labs CP210x USB drivers for host PC. These drivers are available on manufacturer web site

§ Create model and build to generate required binary.

§ Refer below for programming and debugging support.
