Design of high performance DC regulated power supply control circuit based on AT89C51 single chip microcomputer

introduction As we all know, many scientific experiments are inseparable from electricity, and there are often special requirements for power on time, voltage, current and dynamic indicators in these experiments. Therefore, if the experimental power supply not only has good output quality, but also has multi-function and certain intelligence, many inaccurate human operations will be […]

Design of water lamp control based on AT89C51

Because the program pattern display is more complex, so you can write the program by looking up the table, simple. If you want to display different patterns, you only need to rewrite the data in the table. Water lamp program: # include “reg51. H” #define uint unsigned int #define uchar unsigned char const table[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}; void […]

Design of rs232-gpib controller based on AT89C51

More and more measuring instruments provide GPIB (general purpose Internet bus) bus interface, through which instruments and computers with GPIB interface can be easily and quickly connected to form a GPLB network. When GPIB equipment is connected with computer, it needs to use GPIB interface cards, but these GPIB interface cards are expensive, which brings […]
