Here, we introduce the concepts of time domain and frequency domain. The time domain shows how the amplitude of a signal varies over time. In the time domain example, we create an unusual waveform by adding two sine waves. One is a sine wave with a peak voltage of 1V and a frequency of 1kHz, … Read more
Click the blue text to follow Optimizing ADC sampling accuracy is a key skill in microcontroller development, especially when processing sensor data. An inaccurate ADC sampling result can lead to system failures, such as significant errors in temperature sensors, causing devices to overheat or become too cold. Today, let’s discuss how to improve the accuracy … Read more

Introduction The ADS1115 is well-suited as an introductory ΔΣ ADC for several reasons: Two major players in the maker community, Adafruit and Seeedstudio, have written tutorials on its use with Raspberry Pi, see [1], [2]. It is included in the TI High-performance / Precision ADCs series, albeit at the lower end, as shown in Figure … Read more
Previously, we introduced two parts of the router SoCs in the WiFi 6 era, but that was a long time ago. After Xiaomi entered the router market, it must be said that the router industry is becoming increasingly competitive. In the past, you could only buy various low-quality ROMs from TP-Link, but now even TP-Link … Read more
