In actual projects, we often use mif (or coe) files to initialize ROM, but it is cumbersome to write mif (or coe) files by ourselves, and sometimes we may not write them correctly. Here we provide a m...
The pulse circuit composed of photoelectric coupler The photoelectric coupler introduced here is a device composed of light-emitting diodes and photosensitive transistors. The light-emitting diode con...
Can't analyze file -- file E://quartusii/*/*.v is missing Cause: Tried to compile a non-existent file. The file may have been renamed or deleted. Action: Ignore it. It will have no effect....
In my program, there are timer 1 interrupt and SPI interrupt, and the global interrupt has been turned on. I only wrote the interrupt service routine for timer 1. An SPI interrupt occurred in this int...

1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
In recent years, with the increasing maturity of LED technology, LED light sources have been increasingly widely used due to their advantages of using low-voltage power supply, low energy consumpti...[Details]
