Many people should know about the short board theory, the main idea is that a cask can be filled with a minimum of a plank to decide, even if there are a lot of tall wood still cannot hold more water, short board theory in many respects are reflected, such as the dam cordon also has the shortest section of the dike decision, such as the domestic minimum consumption level, also has the lowest income of that
Today we use fireworks to make a pendulum-style bulletin board.
See the effect chart first.
1, create a new file, canvas background color selected white. Also set the canvas size slightly larger.
2, using the Fwmx2004 vector tool, draw rounded rectangle, optional one texture effect fill, as shown.
3, input text.
4, draw a small circle in the upper right and left corner of the rounded rectangle, as shown in the figure.

What is U-bootThe Bootloader of the hi3518ev200 veneer adopts u-boot.U-boot is a commonly used in embedded systems Bootloader,bootloader is a small program executed before the operating system, through which we can initialize the hardware device, establish the Memory space mapping table, thus establishing the appropriate
The new PCB file defaults to the 2-layer board, which teaches you how to set 4 layers or even more multilayer boards.
On the toolbar, click design-->layer Stack Manager. After entering the display is a two-layer board, added as a 4-layer board, usually first point top layer, then add layer, and then add layer, so it becomes a 4-layer

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

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.

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.

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
