1 Introduction
With the rapid development of modern economy, people's living standards have been greatly improved, so the demand for quality of life is also tending to high standards, precision, diversification standards, people's demand for the market has been at an essential level, the demand for market size in favor of concentration, diversity, convenience, uniqueness, Therefore, the formation and development of the market is imperative. The gradual expansion of the size of the market to ach
This two days wrote an LED driver, online also read a lot of posts.
Start thinking very clear, is to see the circuit diagram first, found that LED lights are connected to the GPM port,
Then look at the s3c6410 data manual, first to Gpmcon mouth to write command words, let gpm0-5 set to output, and then to the gpmdat mouth write data words, in the gpm0-5 pin pull low or pull high level,
Thereby controlling the LED's light and extinguish.
1. Circuit diagram
It's obvious that the LED lights are un
Toplayer (top) Draw the line is red, is the general double-sided board on the upper layer, single panel can not use this layer.The Bottomlayer (bottom) line is blue, which is the line above the single panel.MidLayer1 (middle layer 1) This is the first layer, as if there are 30 layers, the general design staff can not use, you do not have to control him, multi-panel time use. The default is not displayed in 99SE and is not available.Mechanical Layers (

Board--tpyboardv702, this board can locate, send text messages, telephone, and on-board temperature and humidity sensors, photosensitive sensors and buzzer, can DIY a lot of interesting things, below we can use this board and a pressure sensor to do a small weather station, To get a real picture:TPYBoardv702Positionin
Bo Master's first article, Hope Toto support.
1, the first is the wiring.
VCC corresponds to Arduino Development Board 5V
GND Connection Gnd
TXD Connect TX
Rxd receiving RX
GPI00 Connect Gnd (This is uploaded when used, upload must be grounded, otherwise it will cause upload failure)
Wiring is not very simple.

SQLite, a lightweight database that adheres to the acid-related database management system, is designed to be embedded and is now used in many embedded productsIt occupies very low resources, in the embedded device, may only need hundreds of K of memory is enough. It can support Windows/linux/unix and so on mainstream operating system, and can be combined with many programming languages, such as TCL, C #, PHP, Java, and ODBC interface, also compared to MySQL, PostgreSQL, the two open source worl

recently, due to the drive experiment on the TQ2440 (ARM9) board, cross-compiling is done on the host (ubuntu13.10) for the system kernel on the front target board. One, cross-compiling of the kernel: 1. Prepare 2.6.30.4 version of the kernel source package, which I use the embedded company provides kernel source package linux-2.6.30.4_20121214.tar.bz2. 2. Open Terminal Input command: Tar vxjf linux-2.6.

The switch in the use of the process, in a dual-machine state can not run, through detection, the signal is the standby side of the circuit board is not normal.
This fault is obviously a hardware failure. First of all, we can replace the circuit board of the standby side with the replacement method. If the fault is still not gone, the real fault is not here. Racks, modules, power supply and connecti
We can see all kinds of message boards on many websites, which is one of the main means of communication between website and visitor. A reasonable design, the interface beautiful message board program can reflect the site from the side of good service, to visitors to leave a good impression, enhance the user's confidence in the site. The message board from the procedural point of view is actually very simpl

Thermal conductive epoxy resin (Generally, silver-doped epoxy resin is used) to cover the placement point of the silicon wafer. Then, the silicon wafer is directly placed on the substrate surface and heat treated until the silicon wafer is firmly fixed to the substrate, then, the SI welding method is used to directly establish an electrical connection between the silicon wafer and the substrate. The bare chip technology has two ma
1. First install the TFTP server in Linux, see the previous article reproduced in the log. It's basically no problem.2.

The original because in school with IPv6 net plus Bras,ip is automatically obtained, so before Linux Internet use is NAT, instead of bridging, is not know the IP of
