convention, rotation in one direction is positive. A good gyroscope specification will tell you which direction is positive, otherwise you'll have to test which direction of rotation will cause the output foot voltage to increase. It is best to test with an oscilloscope, because once you stop the rotation, the voltage will fall back to the 0 rate level. If you are using a multimeter, you have to maintain a certain rotational speed for a few seconds a

on the problem, after finding the problem and resolving it, remove the piles so that the end product is not affected.4. Add external tool for inserting pilesWhen debugging hardware, you can use Multimeter, oscilloscope, logic Analyzer, Spectrum meter and other instruments to observe the hardware. Note that all instruments must have sufficient speed and accuracy to be able to measure errors, such as the problem of 230M signal saturation distortion can

the PLL inside the module. The Qualcomm platform is 24MHZ. The Broadcom platform is 26MHZ.3, using a multimeter to measure the camera's power pin, to see if the camera power supply is normal;(2) AVDD Analog circuit power supply 2.8V, under normal circumstances, AVDD need separate power supply, power ripple Iovdd/dovdd/vif:power support for IO circuits 1.8VDVDD Digital Circuit power supply 1.2V, if IOVDD is 1.8V, it is recommended to use sensor intern

ArticleDirectory High-impedance Mode High-impedance Mode High-impedance mode is a common term in a digital circuit. It refers to an output state of a circuit. It is neither high nor low. If a high-impedance state is input into a lower-level circuit, there is no impact on the lower-level circuit, and it is the same as not connected. If you use a multimeter for testing, it may be high or low, depending on what is next to it. Essence of the high-i

the figure is the A17 line. In order to make the security chip feel that the flash Address has been cleared, we need to pull it out. Use a tool to scrape the outer coating and weld it online, but never cut the A17 wire. Then weld another wire at the place indicated by the arrow. Connect the two wires to the switch. This step is complete. Use A multimeter to test whether the two wires just welded are short-circuited or connected together. Th

, senior engineers are at a high level, TVs with any difficult problems can be repaired, and the repair rate is significantly lower than that of engineers, but the repair cost is relatively higher, therefore, this is the customer's choice ".Hospital Director: "My TV should not be a serious problem. It's just a general engineer ".Repair Shop reception staff: "Well, please pay 20 yuan for the repair fee first ".Hospital Director: "Why do I have to pay for the repair "?Repair Shop reception staff:

data on the output port can be input at the same time. Therefore, you still need to have the bus control and management to access which port, and the three-state buffer of that port can be transferred to the output status. This isTypical three-state gate Application. If there are no more than two output devices online, of course, there are no three-state gates, and the line or logic is another matter. ++ High-impedance mode is a common describe in a digital circuit. It refers to a type o

Depressing asp! Depressing PV! The reason is that sometimes the MCU + FPGA/CPLD joint debugging is not enough for me to use epm240t100c5n, instead of drawing a larger resource CPLD, I chose ep2c5t144c8n, which is the most cost-effective FPGA. I drew a board, invested in Shenzhen, waited for the Board and other components, and finally got everything ready one day. I had nothing to worry about, so yesterday I calmed down and shouted a board. It was pretty Haha, but I was scared, i'm afraid I wo

MCU Low Power Design (ii) practiceKey Words:MCU low power consumption, stm8l low power consumption, energy saving practice, IAR development environment, ammeter measurement power consumptionIntroduction:Energy consumption is a major problem with battery-powered products, and once the power is exhausted the device will "strike". In the MCU low power Design (a) theory, we introduce the principle of energy saving, this paper uses multimeter and MCU circu

increase the interactive link, we insist on small classes, each class of 15 people, full class will be selected according to the sequence of registration after the class. Choose 1 Squad Leader. To ensure that each student to configure 1 high-performance computers 1 sets of +1 arm experimental tools.The company's research and development labs are open to students, and students can learn to use the multimeter, oscilloscope, Logic Analyzer, Digital Brid

value is correct2) to see if the crystal oscillator is working properly, you can use the oscilloscope to view3) Check the minimum system has the wrong connection, circuit breaker and other problems, with a multimeter.(Linux) briefly describes the initialization process for embedded Linux systems. The embedded Linux system starts by running bootloader, then booting the kernel by bootloader, the kernel checks and initializes the hardware device, loads

using MPU6050 internal dmp to calculate Euler angle, read Euler angle directly, eliminate the software data fusion calculation, improve program efficiency. At the end of initialization, set the target posture, enter the loop function, continuously detect whether the MPU6050 data is accepted, and once the effective attitude data is received, the attitude control function is entered. In the attitude control function, using the current four-axis aircraft roll (tumbling) and pitch (pitch), yaw (yaw

-impedance state this is a common language in a digital circuit, refers to the circuit of an output state, is not high or low level, if the higher impedance state and then enter the next level of the circuit, the lower circuit has no effect, and the same, if the multimeter can be measured by the high level may also be low level, It depends on what is attached to the back. The essence of the high-impedance state: When the circuit is analyzed, it can be

First, the TTL lineWith a multimeter measurement, you can determine "GND", the first pin (pad for the side) is "Tx", followed by "Rx", "GND", "VCC".Second, tool preparationDownload the TPTPD software tool with the iconThree, start the brush machine1.

testing, hardware testing has the following notable features: Conformance testingThe same product, the test data of multiple hardware products will inevitably differ. Therefore, in the product verification testing process, we need to test multiple products simultaneously in order to assess the consistency of the test data of each product, that is, whether all within the scope of eligibility? The hardware only has the concrete good consistency, can carry on the mass production. Envi

MQTT can manage to support different? topics., in a simple hierarchy, but that really isn?t enough even in some simple CAs Es. For example, imagine a fleet of electric delivery trucks. Some days, your might want to find a problem with part of your fleet, but not affect ordinary operations by stealing

"Management Tools", and then double-click "Computer Management"; B. click system tools, and then click Device Manager. C. expand the "Ide ATA/atapi controller" Node; D. double-click your "Main ide controller"; 2. Check whether the CPU and the fan are operating properly and cooling enough. When the CPU fan speed slows down, the CPU temperature increases. To protect the CPU security, the CPU automatically reduces the Running frequency, which causes the computer to run slowly. There are two method

this time, the output status of the IC is unstable (if the output signal of the IC is different when 0 and 1 are input), an error may occur.For the output signal of an IC, if it is a high-impedance output, it represents a high impedance and can be considered as disconnected. ---- A high-impedance state refers to an output state of a circuit. It is neither a high-voltage nor a low-level State. If a high-impedance state is input to a lower-level circuit, it has no effect on the lower-level circui

is too large, it also causes frequent host crashes or restarts. In this case, we use a multimeter to test its voltage. It is best to replace an excellent power supply for troubleshooting. Solution: Change the high-power computer power supply. 4. The mains plug of the switch power supply of the host is loose, poor contact, and no plug-in is tight. In this case, most of them will occur on DIY machines. the power cord of the host power supply is not cer
