Summed up, the user used most of the main control chip is a group of Phison and Skymedi Tai. Now let's take a look at their pros and cons. Group Ph

Single chip multiprocessor (Chip multiprocessors, referred to as CMP), also refers to multiple cores. CMP is proposed by Stanford University, the idea is to integrate the SMP (symmetric multiprocessor) in the large-scale parallel processor into the same chip, each processor executes different processes in parallel. Compared with CMP, the flexibility of SMT proces

In the past few days, the serial port communication of arm was achieved. Because of the previous single-chip microcomputer basics, we chose 51 single-chip microcomputer and Its experiment. The experiment is to compile a serial communication program under Linux, compile the program, and download it to the arm board for running, to verify its feasibility. In Linux, the serial port program is to write a data i

The production of CoB is basically the same as that of the IC sealing process. In addition to changing leadframe into a PCB and changing the sealing process from molding to dispensing, with triming Marking missing, plating is missing, but plating is already included in the PCB coding process. In addition, it also has a high requirement on the stability of the environment, because the recent cob programming also involves the evolution of the chip prog

When using the STC single-chip microcomputer, do you encounter a problem: the delay is often difficult to grasp. Of course, you can use the latency function to generate waveforms and output them to the oscilloscope for observation to modify the latency parameters. However, there is no way to determine the latency parameters when there is no oscilloscope. I have created a method here to share it with you.In this way, first set the timer time of the tim

This article introduces a program of 51 series single-chip microcomputer that uses pulse width modulation (PWM) to control the brightness of LED lights. We all know that 51 Single-Chip Microcomputer itself has no pwm interface. This program is The software simulates pwm and adjusts the duty cycle of high voltage and low level in a certain frequency square wave to realize the brightness control of the LED la

This project has been in operation for four months. Two weeks to find the microcontroller internal ad touch screen information, two weeks to select both with USB and with AD appropriate microcontroller. Two weeks of testing and demonstration, draw a schematic diagram. Then make the PCB and debug the engineering code. The successful experiment function is only the first step. debugging the Flying Point and filtering the AD data are the difficulties of subsequent work. 1. Implementation principle:

Instructor Yang,Hua Qing vision embedded college lecturer. There are two 32-bit timers in the lpc11cxx chip, which can be used for timing or counting. With a one-way 32-bit capture channel, the current value of the timer can be captured or interrupted when the input signal changes. It has four external matching registers and four external output registers. In addition, each register can allow up to three matching outputs to be used as a single side

We have already introduced many applications of the HART protocol. Here we mainly discuss another application of the HART protocol in the industry-the application design of the modem chip SYM20C15. In industrial control, the field instruments generally use 4 ~ 20mA standard. In order to expand the digitization function of existing instruments so that they can not only transmit measurement data, but also transmit diagnostic information, the existing fo

First, busA bus is a public channel that transmits information between parts of a computer. There are two kinds of internal bus and external bus in microcomputer. The internal bus is the connection between the internal CPUs. The external bus refers to the connection between the CPU and other components.There are three types of external bus: Data bus, address bus ab (address bus), control bus CB.Second, the basic timing(1) Oscillation period: Also known as the Always cycle, is to provide a single

Single-chip microcomputer refers to the program counter (Programs Counter). The program counter PC is used to store the next instruction address to be executed, is a 16-bit dedicated register, can not be manipulated by the MOV instruction, is not visible to the user. When executing an instruction, it is necessary to take the instruction out to the instruction register according to the address of the instruction stored in the PC, which is called "Fetch
