I bought a 7-segment LED digital tube with ten pins, but the pins are not on the upper and lower sides, they are on both sides of the left and right. Best reference answer:Use a digital multimeter for pin-by-pin testing. Generally, the 10 pins are 7 segments and two public segments plus one decimal point.The public end is generally in the middle or at the mo

to set whether to display the selected inner electrical layer split area. If this option is selected, the thumbnail of the network area divided by the area in the inner electric layer is displayed in the box below it, the pins, pad, or cables with the same name as the Intranet electrical layer network are highlighted in the thumbnail. If this option is not selected, the cables are not highlighted. Show net for option. Select this option. If the netwo

engineers are still confused about nor and NAND Flash. Phase "Flash Memory" is often used with phase "nor memory. Many insiders do not know the advantages of NAND Flash compared with nor, because in most cases, Flash is only used to store a small amount of code, so nor flash is more suitable for some. Nand is an ideal solution for high data storage density. Nor is the primary non-easy-to-lose Flash technology on the market. Nor is generally used to store a small amount of code. Nor is mainly us

dip8 is double-row, each row has four pins, the distance between the two rows is mil, the distance between the pad is 100mil. Sipxx is the encapsulation of a single row. And so on. It is worth noting that the packaging of transistors and variable resistors is the most headache. the PINs may not be the same for the same packaging. For example, for packaging such as TO-92B, usually 1 foot is E (emission pol

before the disk I/O adjustment. 1.2.1 Library Buffer Adjustment The database buffer contains private and shared SQL and PL/SQL zones. the hit rate of the database buffer is determined by comparing the hit rate. To adjust the database buffer, you must first understand the activity of the database buffer. The activity statistics of the database buffer are kept in the Dynamic Performance Table v $ librarycache data dictionary, you can query the table to learn about its activities and determine how

, looks like:Look at those protruding pins, here is the pin callout diagram:Note the two pins labeled with the red circle, which are the two pins that the 80386 processor has left out for interrupts. Where Intr is a shielded interrupt input port, NMI is an unshielded interrupt input port.So how is the interrupt entered into the processor? So many external devices

Of course, for the establishment of this channel connection is a certain condition, that is, the Bluetooth set up to be able to connect the at mode0x0:softwareserial LibraryThe existing Arduino hardware supports pin 0 and 1 (connected to the computer via USB) for serial communication. The serial is carried out via a hardware called UART (chip built-in). This hardware allows the Atmega chip to receive serial communica

Ipv335 has three internal SCI modules: SCIA, SCIB, and SCIC. Each SCI module has a receiver and transmitter. Each SCI receiver and transmitter has a 16-level FIFO (FirstInFirstOut first-in-first-out) queue, they all have their own independent enable bit and interrupt bit; can work in half duplex or full duplex mode; 28335 SCI module 1. Introduction Ipv335 has three internal SCI modules: SCIA, SCIB, and SCIC. Each SCI module has a receiver and transmitter. Each SCI receiver and transmitter has a

bus is mainly used as external memory interface, such as Texas Instruments (TI) C6000 series DSP external memory interface, can support external synchronization SDRAM, Sbsram and FIFO, but also support asynchronous SRAM, Flash and so on. The external memory interface can also be used for interconnection with an in-board FPGA or ASIC chip, in which case the FPGA or ASIC simulates a DSP-supported memory interface, and the DSP accesses the FPGA or ASIC as memory. This type of synchronization inter

order to spare microcontroller pins, additional logic and make the PCBs simpler–in order words, to lower the costs– Philips Labs in Eindhoven (the Netherlands) invented the ' inter-integrated circuit ', IIC or I²C protocol that only require s 2 wires for connecting all the peripheral to a microcontroller. The original specification defined a bus speed of up to Kbps (kilo bits per second). The specification was reviewed several times, notably introduc

Several pins in the upper left corner are J601 and J801, respectively.J601:First row of two pins: jumper caps can be used to shorten the function: Connection: Automatically starts when the power supply is switched on Disconnect: Need to press the top middle of the small button 3-4 seconds to start Second row of two pins: Connection: You can burn

Tq335x's rewritten touch drive is written according to the multi-touch B protocol, using the Tslib test normally, at the end of the article.TN92 touch screen using the touch chip is GT811, below we analyze the touch screen driver writing.(1) View schematic diagramAs you can see from the touchscreen schematic, there are four pins connected to the GT811 board, namely SDA, SDL, int, and reset. Where I2C_SDA and i2c_sdl are connected to the I2C1 port on

hardware maintenance, board maintenance is one of the most important items. Take over a faulty motherboard, how to determine the specific components of the problem? Main cause of motherboard failure 1. Human failure: Live plug I/O card, as well as in the Board card and plug when the improper force caused to the interface, chip and other damage 2. The environment is bad: static electricity often causes the motherboard chip (especially CMOS chip) to be penetrated. In addition, the motherboard

components of the problem? Main cause of motherboard failure 1. Human failure: Live plug I/O card, as well as in the Board card and plug when the improper force caused to the interface, chip and other damage 2. The environment is bad: static electricity often causes the motherboard chip (especially CMOS chip) to be penetrated. In addition, the motherboard encountered power damage or power grid voltage instantaneous spike pulse, often damage the system board power plug near the chip. If the m

Computer motherboard failure to boot solution: The motherboard's power-on circuit control way, has through the South Bridge direct control, has through the I/O direct control, also has through the gate circuit control. Regardless of the Power-on circuit control mode, they are the same principle, that is, through the Power-on key to control the ATX power output, so that the motherboard to the electrical work. ATX Power supply on standby 9 feet have 5V voltage, this voltage is for the power-on c

Detect the ATX power cord to the pool short circuit, and then follow the line run circuit to find the related damaged components for the swap. 3. Check the soft boot circuit If the power can be powered by force, the fault in the soft boot fault itself, at this point should be the focus of the soft boot circuit itself and the soft boot circuit has links to some other circuits.
