History
Ondrej Kosta f6420436eb feat(esp_eth): a new folder structure of the driver and other improvements 
Fixed memory leak in emac_esp_new_dma function.

Polished ESP EMAC cache management.

Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO
initialization.

Added ESP EMAC GPIO reservation.

Added check for frame error condition indicated by EMAC DMA and created a target test.

Async Requests Handlers HTTPD Server Example

The Example demonstrates how to handle multiple long running simultaneous requests within the HTTPD server. It has the following URIs:

1. URI \long for demonstrating async requests running in the background
2. URI \quick for demonstrating that quick requests are still responsive
2. URI \ index page

How to use example

Hardware Required

  • An ESP-Dev-Board (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
  • A USB cable for power supply and programming

Configure the project

idf.py menuconfig
  • Open the project configuration menu (idf.py menuconfig) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/README.md for more details.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
