For example, Fetion, right? What software and hardware knowledge do I need to do this? For example, what functions, controls, APIs, etc. do I need to use when developing in different languages? What u...
Is the stack initialization in the startup code just to define the length of the stack to be used? For example, for IRQ interrupts, the book says that the heap space needs to be applied by yourself, w...
Abstract: This paper introduces the design and production of the band transceiver component. The whole component consists of a low phase noise oscillator, a filter, a power divider, a transmitting swi...
The following situations are all tests of memory conditions on the development board provided by the manufacturer: Memory: 64MByte SDRAM (2 pieces of 16-bit SDRAM chips form a 32-bit interface) NOR Fl...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
Remote keyless entry (RKE) systems have become popular with users, with more than 80% of new cars in North America and more than 70% in Europe equipped with RKE systems. In addition to the obvious ...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
At very low temperatures, certain metals and alloys lose their resistance to electric
current
and become
superconductors
. Two parameters that are often measured are the transition ...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
The serial interface real-time clock chip DS1302 launched by Dallas Company in the United States can trickle charge the backup battery of the clock chip. Due to the main features of the chip such a...[Details]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]

The launch of Shenzhou IX is imminent, and Tiangong is welcoming visitors again. Yesterday, Professor Fu Qiang, Vice President of the Institute of Science and Industrial Technology of Harbin Instit...[Details]
At present, with the diversification of portable products and the almost harsh requirements for audio and video parts, the power consumption requirements of the whole machine have been raised to a ...[Details]
It should be understood as follows: DC-DC means direct current to direct current (conversion of different DC power values). Anything that meets this definition can be called a DC-DC converter, incl...[Details]
Synchronous buck designs are becoming increasingly difficult, and the selection of suitable ICs is becoming quite narrow. This Design Idea combines a current-mode PWM IC used in a flyback regulator...[Details]
