online.SIM300 Module appearance The SIM300 is a three-band Gsm/gprs module that operates on a global scale of egsm 900MHz, DCS 1800MHz, PCS 1900MHz Three frequencies, provides up to 10 GPRS multi-channel types, and supports CS-1, CS-2, CS-3 and CS-4 four kinds of GPRS coding schemes. SIM300 internal function modules are:Keyboard and SPI type LCD interface for users to develop their own application equipment.Two serial ports with debug and data output to help developers develop products more ea

. The content of this tutorial is organized This tutorial basically organizes knowledge points in a project-driven manner, using the example application that enables the viewing and modification of employee information. The CDI features involved include: CDI as a dependency injection container for the characteristics and usage. Implementation of declarative transaction management with CDI. With CDI implementation in the session scope to share persistence context. An event that listens on t

of the use of the upper line or up and down line combination of ways; A class room basically eliminates the restriction condition, the air conditioning system uses the below to send the wind, the wiring form is the up-going line; C class room generally use down line, using a number of cabinet air-conditioning to the side of the air supply mode refrigeration, to avoid the next line of restrictions. Room wiring form Once determined, the need to strictly in accordance with the norms and standards

the list above. We need to connect the solder joint Four (ID) with the solder Point five (ground) through jumpers . The solder point four is open in the standard USB data cable, while the solder point four in the USB OTG data cable needs to be grounded. You can weld jumpers anywhere in the data line, as long as the solder joint four and solder point five are connected.Solder jumperThen the end of the operation of the USB cable is completely reduced,

mobile phone inside the app is how to use the phone to connect the infrared tube, we choose 3.5mm headphone port, All these phones have. 2: So we need a 3.5mm aux interface Here we directly apply the Aux interface on the headset Lose the headset head learn the Aux interface we weld the IR emitter diode after welding, add layer wrapping, in order to pull the time convenient, not too long ah, or add a shell. I'm using a heat shrink tube. . Offi

/17737005 With the above three steps, we can write and develop C language code in Windows, remotely deploy it to Raspberry Pi, compile it using the GCC tool on Raspberry Pi, and then execute it. Before writing the code, let's take a look at Raspberry Pi's GPIO interface, as shown in: We need to complete three functions: 1. GPIO controls an LED flash; 2. communicates with the lingxiao Board through a serial port; 3. Outputs the PWM signal to control the steering gear. The following describes th

the various pins of the serial port, we can connect through a USB to UART adapter TTL-232R-3V3 line. Insert the USB interface of the UART adapter into the USB interface of the computer and connect the UART adapter to the serial port of the router. The usage is as follows.Connect the GND of the adapter to the GND of the serial port. Connect the RXD of the adapter to the TXD of the serial port. Connect the TXD of the adapter to the RXD of the serial port. Next, we begin to prepare for the hardwar

the Ethernet frame header. When a VLAN switch receives an Ethernet frame with a tag field, it can use this tag field to select the port to which the request is forwarded, and decide whether to remove the tag, or receive the Ethernet frame without the tag. Based on the port configuration information, decide whether to forward the frame and whether to add the tag...We say that Ethernet is a broadcast network. This Ethernet refers to the physical layer. For the link layer, it is only a part of the

A maximum of 64 keys are supported, and only 35 are used.4. the LCD interface is modified according to the purchased LCD interface, and can be directly connected using the fpccable.So although there are many changes, they are really transplanted, and the initial debugging is not relevant, just to prepare for a later time :) 11 Development ProcessHere is my development process1. design principle diagram (JTAG viewer with wigggler)2.

. (1) PIN spacing of components Different components have different pin spacing. But most of the pin spacing for various components is: an integer multiple of 100mil (Imperial) (1mil = L x 10 (-3 cubic) in = 25.4x10 (-6 power) m), usually mil as 1 spacing. PCB Resources Network-p c B resource Source NetworkIn PCB design, the pin spacing of components must be precisely identified because it determines the pad placement spacing. The most direct method for determining the pin spacing of non-standa

casting shapes can be used to cast casting with complicated shapes, casting with a wall thickness of 0.5mm and a weight smaller than 1g. It can also be combined and integrated casting; Not limited by alloy materials. Casting of carbon steel, alloy steel, ductile iron, copper alloy and aluminum alloy can also be casting of High Temperature Alloy, magnesium alloy, titanium alloy and precious metal. It is particularly suitable for casting of alloy materials that are hard to forge,

Programmers may not have much time to watch the disc, but they certainly like it. Many of their colleagues and friends around them go down from the Internet, regardless of the version and picture quality. I also bought my own discs, But I seldom know the version of D5 and D9 when talking to them. Many of them ask: What is D9? Therefore, I am not looking for information on the basis of my memory. If you say something wrong, please correct it. There are several types of discs on a DVD, the most co
