# DEMO program with ATECC608A on ESP-WROOM-32SE
## Overview
 Running demo programs with ATECC608A on 32SE by setting `WOLFSSL_ESPWROOM32SE` definition

Including the following examples:

* simple `TLS client`/`server`
* crypt benchmark

 The `user_settings.h` file enables some of the hardened settings.

## Requirements
1. ESP-IDF development framework: https://github.com/espressif/esp-idf

2. Microchip CryptoAuthentication Library: https://github.com/MicrochipTech/cryptoauthlib

## Setup
1. Comment out `#define WOLFSSL_ESP32` in `/path/to/wolfssl/IDE/Espressif/ESP-IDF/user_settings.h`\
   Uncomment out `#define WOLFSSL_ESPWROOM32SE` in `/path/to/wolfssl/IDE/Espressif/ESP-IDF/user_settings.h`
    * **Note:** crypt test will fail if enabled `WOLFSSL_ESPWROOM32SE`
3. wolfSSL under ESP-IDF. Please see [README.md](https://github.com/wolfSSL/wolfssl/blob/master/IDE/Espressif/ESP-IDF/README.md)
4. CryptoAuthentication Library under ESP-IDF. Please see [README.md](https://github.com/miyazakh/cryptoauthlib_esp_idf/blob/master/README.md)

## Configuration
1. The `user_settings.h` can be found in `/path/to/esp-idf/components/wolfssl/include/user_settings.h`

## Build examples
1. See `README` in each example folder
