that this is a photo taken from the front of the circuit board, and let's take a look.Here we need to pay attention to the PCB circuit board above the solder point between the connection. 1. It seems to be connected to something (note the position of two o ' clock direction) 2. No connection 3. If the solder joint is connected to a lot of places, it is most likely a GND or VCC pin, but this is not a versatile method. It should be added that the VCC pin is usually made square an

years ago the motherboard had to buy memory particles (chip) himself plugged in on the motherboard (think about why the master was so powerful at that time, this composition principle in practice has been exercised), and then developed SIMM (Single In-line Memory Module) , will be a number of memory particles ( chip ) welded to a circuit board, become memory module, Insert the secondary circuit board on the motherboard. Next, in order to increase the throughput, the width of a memory module fro

. Of course, without these can also write Web applications, but the UNIX network code to write a sudden to win under the write, will think this is really a toy ah.Tls:tls there is a limit on the number of things, but the thread local storage needs to be destructor, that is, I created a local store to save an object, I can set a destructor function pointer, when a thread exits, this function will be automatically called to. For example, you want to implement a per-thread cache (such as Class Jema

single-mode fiber and multimode fiberSingle-mode fiber and multimode fiber are the most common classification methods. Single-mode fiber is a * * *, multimode fiber is orange.Single mode fiber is generally divided into: conventional single-mode fiber and dispersion-shifted fiber.There are 3 common multimode fiber types:OM1,OM2 and OM3. OM1 multimode optical fibers are not included in ITU-T recommendations , but in practice The use of OM1 fibers is quite common. Compared with single-mode fiber

diagram after modification is a principle diagram of the ARM7 target board that can run uClinux. then, several PCB boards are processed according to the principle diagram and corresponding components are welded, A piece of can run uClinux arm7 Development Board made (the corresponding development board schematic, PCB diagram can be downloaded from the http://www.dailzh.net for free ). 　　 Slow down. Although this development board has been welded, it is only a simple combination of a bunch of el

connectors All colleagues engaged in factory manufacturing and production of optical fiber products should be very familiar with this. On-site grinding and factory manufacturing are two completely different methods that are incomparable, the factory adopts five grinding processes from coarse to refined for special grinding machines. On-site manual grinding is impossible to adjust pressure and maintain consistency. In traditional low-speed networks, network applications may accept insertion lo

of the mains power,Increased output current, can be added to the input rectifier bridge, so that the positive and negative half of the power supply can be used, so that the output current can be increased by 80mA,It can also improve the smoothness of the output voltage. In practical application, the potentiometer W, R3 can be replaced with a fixed resistor. The stability of the output voltage must bewhen high, three-terminal voltage regulator IC can be added. This circuit is simple and works as

One into the hardware deep like the sea!Used to be written SCM program and Linux driver, mainly C language, the hardware is also a little understanding, but most of them stay in the dip era of single-chip microcomputer!Now in a smart home project, hardware software to come, on the android. The driver has been made by the boss almost, a lot of drivers have been given to the original, changeConfiguration on the line, and not much difficulty. Now I have to bite the bullet and complete the hardware.

1 weld The JTAG Circuit Adapter Board according to the configuration. I'm using 14pin.2 Install the emulator driver. Complete installation ASI did not install it automatically, the first time to display a question mark, and then manually.3 Setting up CCS engineering4 Final debugging is like this5 Check the information when someone said you "testconnection" a bit, looking for this button for a long time ah.6 If the gel file is selected incorrectly, it

Hot-bar reflow (molten Siena heat welding), the most common function is to use the heat of the melt has been printed on the electronic printing circuit (PCB) on the Siena paste, in order to connect two separate parts of the electronic components, the most commonly seen is the software line (FPB) welding on the electronic printing circuit (PCB).Since the heat of the Hot-bar is the only source of heat, when the heat pressure is in the soft line (FPC) , it is necessary to transmit heat downward to

using the car later, you can only weld the "Bracket" at the bottom and then install it on the cave board like this: Operating System Selection The initial consideration is uC/OS-II. It is very famous (often seen) and has strong functions (sounds like it), and the operating system is also introduced in the books I bought. The US/OS-II Job Scheduling is a fully preemptible Job Scheduling Method Based on the job priority, the low-priority job b

configured with 12 plug-boards at the front end. Each plug-board can accommodate 12 MUD/LCD coupler and can weld 24 cores. Blind board 1 can be configured for unnecessary ports ). The pre-end cable and the cabling on the back of the distribution frame can achieve dustproof and waterproof effects. For detailed installation instructions, see ,).

example, in a building, a colourful motorcycle should use a high-scale value, and objects such as other buildings presented with it should use a low-light mapping scale (less than 1.0).(3) Preserve UVsWhether to protect UVs. Unity can recalculate the UV coordinates used for real-time light map textures to improve its storage and performance. Note: Recalculation processes can sometimes result in discontinuous UV mappings. For example, a sharp edge may be misunderstood as a continuous surface, wh

ensure that the model size is proportional to the cube.This principle seems simple, but it is also very important. Unless you are extremely careful, it is easy to create a model without any scale concept, resulting in a group of objects that are not proportional in size when you import Unity.(3) When arranging the grid, make sure that the character's feet stand at the origin of the coordinates or the "anchor point" of the model. Since the character usually walks upright on the ground, it is eas

」) The following hardware-related experiments are partially replaced. The software uses the compatible configuration on the remote control Genie and connects the connected remote control to perform the test. For the first time, based on the first reference, the left and right channels connecting two diodes to the headset plug are as follows: Lab results: no error occurred. The second experiment was based on the second reference article to weld only

puzzled about multithreading. But don't be afraid of it, if you are afraid of it, you will never conquer it. Haha, as long as you know your temper, we will always be able to conquer it. ◆ Understand the status information of multiple threads and the conversion rules between them? ◆ Under what circumstances will multithreading weld or die? ◆ How can I capture and process a multi-thread welding failure or death? This is just to raise the question. Afte
