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 (

How to convert CAXA electronic board and CAD data? To meet the requirements of cross-language and cross-platform data conversion and processing, CAXA Electronic Board 2009 supports the new development of Unicode encoding and further enhances the compatibility of autocadr12-2009 data from the underlying platform. DWG data can be directly opened, edited, modified and saved, to ensure the electronic

These two days want to try the TFTP download function under the Uboot, so to establish the Development Board and Ubuntu Network connection, encountered some problems in the middle, is recorded, lest forget. 1. At the beginning, whether the PC Ping Development Board or the Development Board ping computer, ping different; Check the information on the Internet, said

If we are ready to assemble the computer DIY, then we first need to determine their own needs, confirm the use of computers, and then according to their own budget to determine the price of the machine. In addition to determining the price and performance of the machine, one thing we need to determine is the size of the machine. The choice of host size is mainly based on two reasons, one is to place the host space, the other is a personal preference. Some people like behemoths, some like small a

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. 5,

Download Uboot,kernel,rootfs to the Development Board 1, why downloadThe so-called download, also known as burning, deployment.1.1. 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

Environment:Development Board: Freescale 2.6 armv71, the system is read only , the only path to read and write is/TMP/SD (this is an SD card). The program is placed under/tmp/sd/transfer (instead of the run path below), and the SQL statement is saved as a file on the Development Board, and the statement character set is GBK. Server: The server is installing SQL Server 2008.Function: The program can connect

Chip on board (COB) 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

In the "can_485_module_v1.x" Hardware data compression package, provide a schematic diagram of the Cadence format andSchematic diagram of PCB, AD format and PDF format.The Linux driver for the 485 module is the "drivers/char/max485_ctl.c" file in the kernel directory, the default kernelThe driver is already included in the image.The test routine provides a "Schindler itop-imx6-minilinux-rs485_v1.x" compression package.1 Hardware ConnectionThe hardware tested in this document is two pieces of ito

Virtual Machines Select the bridge, and disable the wired and wireless network card, open the local connection, local connection properties to write as follows:The IP address is ipconfig after connecting the board with Windows cmd .the network cable of the board is best connected to the switch or router, and then connected to the computer by using another cableIf the direct

First, Environment constructionSOURCE package Download: Git clone https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.10.8.tar.gzOr go directly to kernel.org to download it.Cross-compilation tool chain production:This has already been done in the u-boot transplant: http://www.cnblogs.com/kele-dad/p/6910040.htmlSecond, the kernel boot process 2.1 Windows and Linux system startup difference　　The bootloader determines which single board to start.2.2 Mod

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
