The voice chip is a part of the chip, a voice IC; in Chinese it is also called a sound chip or a music chip. It is an integrated circuit chip that can be controlled by buttons or an MCU and can dir...[Details]

introduction Zeta potential, also known as electrokinetic potential (x-potential), is an important indicator for characterizing the stability of colloidal dispersions. Positive or negative hig...[Details]

1. Experimental tasks Use P1.0 to output 1KHz and 500Hz audio signals to drive the speaker as an alarm signal. It is required that the 1KHz signal sounds for 100ms and the 500Hz signal sounds for 200...[Details]

1 Introduction PWM, the English name Pulse Width Modulation, is the abbreviation of pulse width modulation. It modulates the width of a series of pulses to output the required waveform (including sha...[Details]

In C, the conversion of floating point to integer is truncated, and the decimal point behind is directly removed instead of rounding.  For example: uint16_t(12.89)=12, not 13.  A small function was w...[Details]

Let’s look at the following picture: Figure 1: Circuit 1 In Figure 1, we use switch K to short-circuit the two ends of resistor R2, and then use a multimeter to measure the voltage drop between en...[Details]

A series of industry reports released by GSMA today show that China has maintained its global 5G leadership position, thanks to the large-scale investment of Chinese operators in 5G and the growing e...[Details]

Inverter harmonics are high-order harmonics generated in the input and output circuits during the inverter operation, when the input power needs to be inverted by high-power diode rectification (or...[Details]

Today a customer asked us what capacitive reactance is and how to measure the size of safety capacitive reactance. In fact, measuring the size of capacitive reactance is very simple and can be measur...[Details]

Introduction: This paper designs a time-triggered multitasking scheduler based on AVR microcontroller and applies it to practice. The scheduler uses message passing to enable the microcontroller to s...[Details]
