[] Basic knowledge of Linux: TP-Link WN823N wireless network card (RTL8192EU chip) X86-64 and AARCH64 driver installation, Purpose: Enable embedded devices similar to Raspberry Pi's AARCH-64 architecture to connect to Ethernet over a USB wireless Nic; The device has LAN interfaces. However, after the previous system firmware upgrade, the three internal network interfaces can ping each other, but none of the interfaces can ping the external network int

The 16c2550 serial port chip can be used to expand two serial ports. Its operation method and register usage are exactly the same as 8250, so we can use the classic 8250 driver in Linux to drive st16c2550. 8250 the driver remains unchanged. You need to add the 16c2550 initialization code. In the initialization code, you need to set the chip selection and IRQ pin for 16c2550, configure the read/write timing

Recently found a lot of graduates just into the job of the students to write a single-chip microcomputer program is very confused, do not know where to start, how to achieve the desired function. Although in school to learn the relevant courses, may be the curriculum design or graduation design is to do a single-chip microcomputer design, but from the circuit board to the basic procedures have been done, th

while changing the T1 and T2.The first two methods, which change the period (or frequency) of the control pulses at the speed of the control, will cause oscillation when the frequency of the controlled pulses is close to the natural frequency of the system, so these two methods are seldom used. At present, in the control of DC motor, the fixed frequency method is used mainly. Reversible PWM control system with bipolar drive of DC motorBipolar drive refers to a PWM cycle, as the pulse voltage at

Known as the world's lowest power Bluetooth single chip DA14580 in the wearable market, health care, ibeacon positioning and other markets have been widely used, but because of its more closed technology/data support led to a high level of technical barriers developers, the network also rarely see the development of DA14580 technology sharing, Therefore, the general enterprise and the general technical team are not daring to adopt the platform, but on

I. Single-chip microcomputer three major resources 1.flash--program storage space Equivalent to the computer's hard disk, you can achieve power loss after the data is not lost. 2.ram--Data storage space Equivalent to the memory of the computer, used to store the data generated and required during the operation of the program, data loss after power outage, the advantage is fast reading speed, can be written indefinitely. 3.s

COB (Chip on Board) is a mature technology in the electronics industry, but the general packaging factory is not familiar with its manufacturing process, perhaps because it uses some wire bond (IC) technology to seal the electronic circuit, and the So a lot of finished products or professional circuit board of the foundry very difficult to find the relevant technical staff.Previously, Cob was used mostly only in some low-tier consumer products, the sm

I personally do not really from the zero learning, but it is very brazen to admit that although the University of the single-chip computer courses, and have done a simple course design, but you may also understand that the university will not mind in the practical study, And I do not understand that although the professional is the automation of why I do not want to do the automation of the work, whether it is hardware or software, in the bottom of my

judge the realization of the function, it is not introduced. Here are a few common:1, Lobyte () and Hibyte (). As you can see from the name, take a low byte and a high byte of the word length. These two macros are often used in the initial load of the timer. Almost all programs on the Internet or in books are like this:TH0 = (65536-x)/256;TL0 = (65536-x)% 256;In fact, this assignment is very non-intuitive, why should high-byte divided by 256? Low byte Why do you want to take 256 redundancy? Is
