The discrete component touch switch circuit is shown in the figure below. The circuit consists of a sensing amplifier, a memory, an AC driver, etc. When a finger touches the insulated metal plate, a ...[Details]
Many LCD modules use resistive touch screens, which are equivalent to sensors that convert physical positions into voltage values representing X, Y coordinates. There are usually 4-wire, 5-wire, ...[Details]
Many friends have this question: Nowadays, solid-state drives are measured in T units, and the memory of mobile phones and computers is 8G or even 32G. Why is the RAM of microcontrollers less than 1M...[Details]
The research on the principle of wireless charging technology can be traced back to the 1830s, when scientist Michael Faraday first discovered the principle of electromagnetic induction, that is, ...[Details]
1. Introduction
The standard structure of MCS51 microcontroller has only one full-duplex UART serial port, P3.0-RXD for receiving and P3.1-TXD for sending. If you want to complete multi-channel...[Details]
We already know that the symbols R7 and R6 in the program represent RAM units, which are used to store data. Now let's take a look at the meanings of other symbols.
DELAY: MOV R7, #250...[Details]
The control program in this example does not use the (timer) interrupt function of 80C51, but uses a for loop as a delay function to roughly provide a delay of 0.5s and 1s. The control logic of thi...[Details]
Rohde & Schwarz and NOFFZ, a market-leading supplier of custom test systems, have collaborated to integrate the proven R&S compact test range (CATR) technology and the advanced radar echo simulator R...[Details]
1.7.1 Change UART2 to a normal serial port driver The S3C2440 chip has 3 serial ports: UART0, 1, 2. The Linux-2.6.32.2 we downloaded already has a complete driver for UART0, 1, but it uses infrared...[Details]
Radar level meter is a highly reliable, non-contact measuring instrument. It is precisely because of the characteristics of non-contact measurement that the instrument does not directly contact the...[Details]
