1. What is ESP32? ESP32 is a series of 32-bit microcontroller chips launched by the Chinese manufacturer Espressif, integrating Wi-Fi and Bluetooth dual-mode (Bluetooth 4.2/BLE). It is based on the Tensilica Xtensa LX6 core, featuring powerful networking capabilities and peripheral expandability. Since its release in 2016, it has gained immense popularity in fields such as … Read more
In increasingly complex wireless communication systems, achieving high performance and low power consumption in digital signal processing (DSP) under process-constrained environments has become a significant challenge for chip architects. At the fifth RISC-V China Summit’s Frontier Innovation Technology Sub-Forum, Li Gaoshan, a senior expert from ChipRise Technology and a top talent from China Mobile, delivered … Read more
The control gate of the underground water well pump at my hometown can be remotely controlled from a distance using a remote control. This way, when watering, one does not have to run over to push the gate, which is very convenient. Last time I went home, my mother said the accompanying remote control was … Read more
Introduction ZigBee® and Bluetooth® are wireless communication protocols that provide a set of specifications for devices to transmit information wirelessly. The newer Bluetooth protocol, Bluetooth Low Energy (BLE) or Bluetooth Smart, was introduced as a low-power protocol, while the original Bluetooth is now referred to as Bluetooth Classic. Launched in the 1990s, the older technologies … Read more
In addition to 3G/4G/5G, Bluetooth, WIFI, and RFID, the Zigbee protocol also supports the Internet of Things (IoT)! Now, let’s take a closer look at how many layers the Zigbee technology protocol consists of. 1. The Zigbee protocol stack is a key element in supporting IoT applications. The Zigbee protocol stack can be divided into … Read more
In a previous article, I introduced the basic knowledge of SPI, see <<SPI>>. This time, I will present a design of a wireless communication system based on the 51 microcontroller, focusing on how to achieve data transmission between the microcontroller and the wireless module through the SPI (Serial Peripheral Interface) protocol. The system uses the … Read more
Introduction: From “Lighting Tool” to “IoT Dominator” “In 2016, a Chinese chip emerged, priced at only 1/3 of Arduino, yet 5 times more powerful – it is called ESP32, and today, 1 in every 3 IoT devices globally uses it.” Today, we will discuss how this “budget-friendly” chip has revolutionized hardware development, even causing concern … Read more
