Recommended Interconnection Methods for Phyphox and External Sensors ——Also answering a question from a certain student at a university Since I started using microcontrollers to expand the external sensor technology of Phyphox about one or two years ago, I have experienced the process of connecting Phyphox with ESP32, Arduino UNO + Bluetooth BLE, Arduino Nano … Read more
Implementing edge computing in embedded systems is becoming increasingly popular, with several platforms beginning to support it, utilizing TinyML – compact machine learning. In addition to the eighth edition of Arduino Nano 33 BLE launched by our company, ESP32, QuickLogic’s QuickFeather, and PICO are also building an ecosystem around TinyML. We will gradually launch activities … Read more
Previously, I wrote a few examples of how to use C# to write STM32 programs. Similarly, we can also use C# under ESP32, relying on the ever-growing .Net nanoFramework. Currently, it supports more and more development boards and chip types, and the related libraries are also increasing. The supported devices can fully support conventional application … Read more
Hello, I am Little Fish who loves fish-flavored dishes in ROS. In the last section, we completed the measurement of distance at a specified angle. This section will synthesize it into a ROS LaserScan message and publish it to the upper computer through Micro-ROS, ultimately achieving visualization in RViz2. Hardware Development Platform For convenience in … Read more
| Indoor Test Flight | After the Storm, the Rainbow Appears To enable the BETAFPV 915 Nano to support PPM output from the FUTABA T14SG, an ESP32 development board was used. After coding twice with Mu Ge (Bilibili ID: Er Mu Shan Ren), it was finally ready for test flight. Although ELRS is high refresh, … Read more
The battery compartment for the remote-controlled plane has been designed and sent for sampling; however, the cockpit is not yet completed. Let’s first work on the remote control and data transmission. This article mainly introduces the UDP data transmission of ESP32C3, where ESP32C3 acts as a UDP server operating in AP mode. First, here is … Read more
This article will introduce how to create a wake-on-LAN device using ESP32 hardware and implement the WOL (Wake-on-LAN) function through .Net nanoFramework, sending WOL packets to wake up remote computers. 1. Background In previous articles, we introduced how to use libraries related to .Net nanoFramework to achieve various functions, such as reading sensor data, controlling … Read more
