There are different kinds of microcontrollers launched by Espressif such as ESP32, ESP32 (C series), ESP32 (S series), and ESP32 (H series). These microcontrollers or Systems on Chips (SoCs) can be programmed using ESP-IDF in different languages such as C and C++.
Prominent Features of ESP-IDF
ESP-IDF has the latest features and software components. It offers multicore support, peripheral devices, high connectivity, strong security, and networking protocols.
Standard Programming Interface
The ESP-IDF offers different standard programming interfaces to program ESP32 chips. These include C or C++ libraries, Berkeley Sockets BSD for network communication, virtual file system support, and POSIX Application Programmable Interfaces (APIs).
Peripherals Drivers
The peripheral drivers that are provided in ESP-IDF’s SDK include Serial Programmable Interfaces (SPIs), Universal Asynchronous Receiver Transmitters (UART), LED and Motor drivers, Timers, Analog to Digital, and Digital Analog converters, and pulse counters.
Wi-Fi
ESP-IDF provides a long-range protocol for Wi-Fi due to which it has enhanced connectivity. It also supports Wi-Fi mesh that has IP connectivity as well as a secure connection. Due to the mesh network of Wi-Fi, the interconnectivity of devices is improved.
Security
Over time, Espressif has improved the features of its devices and software to protect them from data breaches and cyber-attacks. Therefore, ESP-IDF now offers secure boot, cryptographic security, and flash encryption. These features are also backed by the hardware design of the ESP32 System on Chips (SoCs).
IDE Support
The ESP-IDF allows users to use extensions of other IDEs. In this regard, it offers an extension for Visual Studio Code and Eclipse IDE plugins.
Storage
ESP-IDF comes with high-level storage interfaces. It has a separate partition manager and virtual file system library. The partition manager combines information on different regions of SPIs in memory so that they do not take separate spaces in memory. Similarly, the virtual file system library unifies interfaces of different drivers in real file systems or file-like interfaces.
Networking Protocols
The ESP-IDF uses different kinds of networking protocols. Some of them are DHCP client and server, TLS client and server, HTTP client and server, Internet Protocols, IPv4, and IPv6.
Bluetooth LE
The ESP-IDF has low-energy Bluetooth that supports global standards and has fast distribution networks. It can also work with Wi-Fi. Bluetooth of ESP-IDF, like Wi-Fi, also uses Bluetooth MESH technology, which allows users to build smart systems and even monitor them remotely.
Documentation
ESP-IDF comes with complete documentation that contains detailed information about the design and use of its software components. It also explains the usage of hardware peripherals. Here is the ESP-IDF Complete Guide.
Conclusion
ESP-IDF is an online framework for handling IoT devices. It is developed by Espressif and used to program a series of ESP32 Systems on Chips (SoCs). It has advanced features that support better connectivity, extensive hardware peripherals, and high security.
