ESP-IDF Tools Installer

===============

download https://dl.espressif.com/dl/esp-idf-tools-setup-2.2.exe
run it
The installer includes the cross-compilers, OpenOCD, cmake and Ninja build tool. The installer can also download and run installers for Python 3.7 and Git For Windows if they are not already installed on the computer.

Updating ESP-IDF tools on Windows:
cd c:/esp-idf
install.bat
Add ESP-IDF tools to PATH using an export script:
export

Build project

===================

xcopy /e /i %IDF_PATH%\examples\get-started\hello_world hello_world

cd <projects>\hello_world
idf.py menuconfig

SDK Configuration/compiler toolchain path/prefix = xtensa-esp32-elf

idf.py build

Generated C:/esp-idf/exercise/hello_world/build/hello-world.bin

To flash, run this command:

=================

run 'idf.py -p COM13 flash'
