In the design of all kinds of SCM application system, often encountered SCM and PC communication problems, in the speed is not high, the transmission distance is not far from the general use of RS 232 standard serial interface to achieve, in the transmission distance from the occasion, there are scholars to study the network to achieve communication between the PC. However, it is an urgent problem to meet both high speed and long-distance PC communication with MCU. With the development of inform

Today write here how to control the speed of the DC motor with a single chip microcomputer. DC Governor is to adjust the speed of the DC motor equipment, the upper and the AC power connection, the lower and DC motor connection, DC governor will

The infrared receiver Head model has many HS0038 VS838 and other functions are roughly the same, but the PIN package is different. Infrared receiver has several unified encoding method, which encoding method depends on the chip used by the remote control, the receiving head received is the same. TV Remote control using a dedicated integrated transmitter chip to achieve remote control code launch, such as To

User Mode (user mode): the normal mode of running the application; Fast interrupt mode (FIQ mode), used to support data transmission or channel processing; Interrupt mode (IRQ mode), used for normal interrupt processing. Super User Mode (SVC mode), operating system protection mode Exception interrupt mode (ABT mode). Enter the data and log on to or prefetch the exception interrupt command. System Mode (sys mode) is a privileged user mode used by the operating system. Undefined mode (und mode). T

[] 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
