Just the other day, I lamented the lack of options when it came to ESP32-C5 boards featuring dual-band WiFi 6 support. The FireBeetle 2 ESP32-C5 IoT development board made by DFRobot shows that I ...

Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring system measures and displays ambient ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

This repository contains a program to calibrate a 3.5" touch screen display shield, as shown below - Most 3.5" TFT LCD Touch displays use the ILI9486 Display Driver and include a resistive touchscreen ...

This repository contains a program to load a BMP Image from an SD Card and display it on a 3.5" touch screen display shield with an Arduino UNO R3/R4, as shown below - Most 3.5" LCD Touch displays use ...

It has now been over 12 years since I built the Elektor DSP radio which used the Si4735 chip from Silicon Labs (now Skyworks). This was the first time an FM radio was built using a DSP circuit to ...

直接数字合成 - DDS是一个非常重要的概念，也是电赛中要考察的技能，一般都使用FPGA + 高速DAC或高集成度的DDS芯片来实现，得到几十MHz的模拟信号。实际上大多数的应用场景需要产生的信号在100KHz以内，完全可以用单片机的程序来实现，如果单片机内部有DAC ...

This is a mini-NTP based on a ESP32. Time will be provided from the GPS receiver and a DS3231 if no GPS-signal is avaliable, to server time to your networkcleints. With the feedback and help from our ...
