Let's talk about the memory Compilation Method in the computer today. For the computer's internal chip, People split it by bit. Let's take the following chip for example:
Memory preparation
There are 8x4 = 32 squares in the picture, that is, 32 bits. The following four lines are data lines used to retrieve data from the chip. When the
In addition to CPU sockets, various slots and interfaces, the motherboard also has many chips. In addition to the Motherboard chipset, most of the other larger chips are functional chips, which provide some specific functions for the motherboard.
1. BIOS chip The motherboard has a very important chip-BIOS chip. It is a flash memory

How can I determine whether the crystal oscillator is working properly?
1. There are many judgment methods. It is most direct to view the waveform with an oscilloscope. You can also test the voltage with the voltage file of a digital multimeter. Because the duty cycle of the crystal oscillator waveform is 50%, therefore, the average voltage measured is about 1/2 VCC. For 51 single-chip microcomputer, wh
act as an added comport independent of any existing hardware in the form of PC application software. The comport uses the application software running on the PC to access a cp2101-based device by accessing a standard hardware comport. data transmission between the PC and cp2101 is completed through USB. Therefore, you can transmit data to a cp2101-based device via USB without modifying the existing software and hardware.

Baidu Encyclopedia: UART: Universal asynchronous transmitter/transmitter, a general asynchronous receiving/sending device. UART is a parallel input into a Serial Output chip, usually integrated on the motherboard, most of which are 16550afn chips.

This is a small experiment I did last semester, but I think the control MCU is more direct than the control arm, because some of the arm is better than the MCU encapsulation, so you are not very in-depth.
If you have learned MCU, it will be easier for you to learn arm, but arm is a little more complicated than MCU.
This code was removed from my previous blog, but I used Sina before. Now I think Sina is an entertainment blog, but blog garden, I think it is a real technical blog website. I hope th
We already know that single-chip microcomputer has Rom, ram, and parallel I/O Ports, so what are there in the single-chip microcomputer besides these? How are these fragmented things connected together?
Next let's make a complete analysis of the single-chip microcomputer!
We can see that in 51 single-chip microcomput

Next let's take a look at whether the above initialization function is available. We have written three functions as follows:
Dm9000_init (), sendpacket (), and receivepacket () are saved and named dm9000.c. Now that we want to debug, when

Today, we finally received the BDM and xs128 core Boards, which can be used to test the fit of the BMI simulator and build the codewarrior compiling environment.

There are four drivers, corresponding to different versions of XP and win7:
① Usbdm_drivers_1_2_0_win_x32 corresponds to the 32-bit win7 System
② Usbdm_drivers_1_2_0_win_x64 corresponds to the 64-bit win7 Sy
Recently, p178g is used, and internal registers need to be controlled to implement the switch and VLAN configuration of each Phy. In order to replace the "pseudo" Switch implemented by the original analog switch, you can use the SMI interface to read and write registers through ds to control the IC operation status.

"Blue Chip" I am afraid a lot of people do not know what it means, I first come and everyone to popularize knowledge, its most important concept refers to "more and more valuable in the long run" means. As a programmer, I think you all want to make yourself more valuable and valuable through practical action.So the question is, how can you make yourself a "blue chip" programmer? Below and listen to me slowl

Many netizens note that the current bustling thousand-dollar machine market is rarely seen in the telecom model, this is because MediaTek has not launched the support of the telecom network chip. This will change, however, and this year MediaTek has reached strategic cooperation with the telecom CDMA patent Authority, and has released its own chip to support the whole netcom.

In the drive development process, we sometimes encounter this application: for example, the firmware of a chip is not fixed, can be upgraded later. Then, every time the system is powered on, a test is required, and if a new firmware is detected, the firmware is upgraded the first time it is powered on. After that, because a new firmware version number is saved for detection, no more boot upgrades are available.

The Phison master chip is used the most, because it is the best compatibility, the production success rate is the highest (99%), and read and write speed is almost the fastest (horror of write 16 read 31), so it is a rookie production of special supplies. But Phison has a drawback, is that it does not support the volume of output USB-CD and USB-HDD at the same time coexistence, which makes people very depressed, especially the author of the two new no
