17 independent buttons are designed to send data. P1^0 to P1^7 and P0^0 to P0^6 are set as independent buttons. Press to send data, and press again to send data. However, P1^0 to P1^7 can send data no...
//The main program starts. Within a certain measuring time T, the number of pulses M generated by the pulse generator (instead of the input pulse) is measured to measure the speed. // ORG 0000H AJMP M...
If you need JINK simulation, I also have a brand new V8 simulator that I bought in March this year and I want to transfer it. It comes with a full set of 20 data disks and original CDs. . . . . The pr...
May I ask which library contains the components 93C56A, relay, ULN2003, photocoupler PC817, and triple "8" digital tube?Is the Elan EM78P447ASP microcontroller available in stock?...
I use the following statements in the evc development environment: pFile=fopen("History.txt","w"); fwrite("history",1,strlen("history"),pFile); fclose(pFile); I can create the History.txt file in the ...
As we all know, software is converted into binary by compiler so that it can be recognized by computer. What is confusing is: How does binary control computer? As far as I know, binary controls the el...
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Blood pressure is one of the important physiological parameters of the human body. Accurate measurement of it is conducive to early detection and identification of hypertension types, and to the pro...[Details]
A biped robot joint constructed by pneumatic artificial muscles is introduced. The joint uses the flexible characteristics of pneumatic artificial muscles to effectively control the impact of the la...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
This issue will briefly introduce the test related to spectrum - occupied bandwidth.
Definition: Occupied bandwidth refers to the bandwidth corresponding to 99% of the total transmitted power, cent...[Details]

As the demand for wireless and wired services in the communications market continues to grow, the telecommunications industry recognizes the need to break away from the shackles of proprietary or p...[Details]
Popular consumer electronics products such as game consoles, digital televisions (DTVs) and personal computers are becoming more and more versatile and feature higher performance. The enhanced data...[Details]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
Most
