LA2132, 32\64 channel G series USB Virtual Logic Analyzer has many advanced triggering functions, but many users do not use these triggering functions, the following describes the use of these features. Timing measurement: The captured data is displayed as a time series.Introduction to LVDS:LVDS is a low-voltage differential signal transmission, is a new technology to meet today's high-performance data transmission applications. Because it enables the system toThe supply voltage is as low as 2V,
System Environment: Virtual Machine Fedoralive131, ls/dev/fb *. Check that no/dev/fb0 device file is created by default. 2. After searching for information, add the fb0 device: modify/boot/grub/menu. lst adds vga = 788 at the end of the kernel startup parameter. Note: No lilo exists in Fedora13. Therefore, you need to modify the kernel startup parameter to set vga in case 7 in grub.

If you need to play video in large venues, need to use two projectors, now the projector, a lot of two video interface, an input, an output, then we use a notebook with two projectors in tandem.
This principle is the same as the computer with dual display video, it is necessary to have a separate video card and have two out of the interface.
Method/Step
1 before doing these things, we first need to determine the specifications of their own instruments performance. We can first lo
Red Hat 9 and runs on vmWare4.5.2, the cpu is Intel P4-2.4's
If you are using AMD cpu, the kernel provided in the attachment may not be suitable for you.
You need a Linux kernel that supports Frame bufferand devfs. If You Want To compile a script, download boot.tar.bz2 in the attachment.
Decompress the package to the/boot directory. If your boot program uses GRUB, add a title similar to the following:

to a large monitor than two working simultaneously. The Mac notebook also offers a "close-cover Mode": The feature introduced from PowerBook G4 can be combined with a notebook's own screen, working with an external screen alone (of course, since the notebook is closed, the external keyboard and mouse are required).
After you close the screen of your Mac notebook, you only need to connect an external monitor, a power supply and a mouse keyboard, and the Mac will automatically wake u
In the MIZ702 study notes 7--try homemade with bus IP, I mentioned the simple usage of axi4-lite, driving the next running lights, only involved in the write bus. Today, I want to use the previous VGA module, the Axi4-lite read and write are applied. This article is mainly about the introduction of ideas, as well as the method of Axi4-lite reading. Some details please read the MIZ702 study note 7--try homemade with bus IP.The specific idea is shown in
In Ise, the set pin can be constrained by opening the Assign package pins in user constraints.

Where the parameters are set as follows
I/O name--io pin name, corresponding to the input and output pins in module.
I/O Direction--Sets the input or output pin.
Loc-Located on the chip.
Bank-the bank block where the pin is located, and when LOC is specified, the bank is determined.

, we have two options:
1. conv_uni_to_pc () conversion is not performed.
2. Load the ing relationship that conforms to the two-byte processing, that is, the 1-to-1 ing of non-control characters is performed. The custom Unicode code table that conforms to this ing is direct. Uni.
To view/load the Unicode ing table of the current system, use the external command loadunimap.
After conv_uni_to_pc () conversion, the characters in "Hello, world. N" are entered in the buffer zone of tty1. Then, do_con_

Apple Watch the debut of the 12-inch MacBook, light thin, really can be called home travel, pick up the necessary x artifact, and there are space ash, silver and tyrants gold three-color optional, and finally changed the MacBook always monotonous color. However, if you are not fully accustomed to wireless life, then, buy 12-inch MacBook Accessories Raiders, presumably you will need.
Because the MacBook's fuselage has only one usb-c connector, want more jacks? Please buy peripheral accessor
by the hard disk controller, and the other data is pumped into the computer via the PCI bus. The hard disk controller here is a dedicated CPU that controls the hard drive for data access in real time. The computer can display the input data in grayscale to monitor the running state of the collected data stream. Monitoring data can be high-power data extraction, as long as the higher than 25 frames per second requirements, you can achieve a good real-time monitoring effect. This processing mode
high-power periods ).7: fib: The logic gate output is the load current at low power usage (for irrigation current ).8: iih: the input of the logic gate is the current of the high current (for the filling current ).9: IIl: the input of the logic gate is the current at low power consumption (for pulling current ).The gate circuit output pole is directly output as the output end without load resistance in the Integration Unit. This form of door is called an open door. Open-source TTL, CMOS, and EC

RGB mode is large screen with more mode, data bit transmission has 6 bits, 16 bits and 18 bits, 24 bits of the points. Wiring generally has: vsync,hsync,dotclk,cs,reset, some also need RS, the rest is the data line. RGB-LCD's memory is played by the system's RAM, so its size is limited only by the siz
Http://www.autooo.net/classid106-id128484-2.htmlThe designers of embedded systems are facing a dilemma. On the one hand they need to reduce system costs. On the other hand, their system is facing the use of relatively narrow, small batch of applications, can not play a large-scale production efficiency. The high-volume consumer applications market provides components that can handle similar tasks and are less costly, but embedded system designers are unable to take advantage of these components
