the operation of the machine with the oscilloscope measurement and observation of the relevant components of the waveform, and the normal waveform comparison, judge the fault site. 6. Simple after complex and combined with the composition of the principle of judgment With the wide application of LSI, the control logic is more and more integrated on the motherboard, and its logic correctness is more and more difficult to judge by measurement. It can

Oh, PC upload a serial drive, then the PC Keyboard/monitor for the embedded board used. 2.2bootloader It's like a knot, you don't understand it one day, and you can't safely develop embedded systems, even though you can write the software very well. When a traditional PC is powered on, the CPU core instruction pointer (such as CS:IP) points to a piece of cured code in the system, such as the BIOS, which is burned i

caused by the failure of the post, some technicians are advised to use a separate socket. Also some netizens believe that the "big cat" power quality is generally bad, anti-interference ability is particularly poor, especially for a long time to use a severe fever, resulting in equipment failure. Therefore, it is recommended to switch to high-quality power supply (only the price is more expensive). 3, the equipment (including the host) for good shielding and grounding Have you ever tried to m

sending pin, it is worth noting that if the serial port only sends a small amount of data, the voltage fluctuation may not be so accurate, in this case, we need to use an oscilloscope or logic analyzer to capture the data activity of the sending pin. (4) Test the RXD pin It is the most difficult to accurately identify the receiving pin because it does not have very effective feature definitions. We usually find the TXD pin through testing, and the ot

as: whether the chip is consistent; whether there is virtual soldering, find an oscilloscope and check if the I2C waveform is abnormal!5. After completing the above work, it does not mean that you have completed all the work. Now, although the sensor has started to work, when you enter the gravity sensing interface, such as system settings.I found that the UI does not rotate at present, or that the next sensor test tool is the same.This is because th

Cetk tools can be used for fun, but I have never done it !!! 20. We-hjb is also a tool software written by the cool-man-register read and write tool. It is used in both wince50 and wince60 versions. You can view SFr configurations at any time. It is a very useful tool software. 21. Compilation switch and debugging code 1 "# If/# else/#

Collect collected information from the Internet: How can I determine whether the crystal oscillator is working properly? 1. There are many judgment methods. It is most direct to view the waveform with an oscilloscope. You can also test the voltage with the voltage file of a digital multimeter. Because the duty cycle of the crystal oscillator waveform is 50%, therefore, the average voltage measured is about 1/2 VCC. For 51 single-chip microcomputer, wh

for them... (They are a marvel solution) I gave up fixing the garbage-like driver... It seems that you still need to write the driver .. Wait for your brother to finish writing this note next week! Brother will solve the problem within two weeks... The pressure is still quite high... Now, this driver is the worship of ATMEL! If brother's company is transformed into a shanzhai mobile phone company step by step, he should consider the way out as soon as possible... Nnd It turns out that the touc

single-chip microcomputer AT89C51 and its peripheral components is 5 V, and the operating voltage of SL811HS is 3.3 V, therefore, the system should provide 5 V voltage for Voltage conversion at the same time. Although SL811HS can use 12 MHz crystal oscillator, but in the actual use process, if the crystal oscillator quality is not good, the circuit stability will be relatively poor. Therefore, we recommend using a 48 MHz Active crystal oscillator during design. The SL811HS interrupt request out

uclk is extracted through clkout0 and viewed with an oscilloscope. When it is found that it is not working, the uclk is not stable at all. so think carefully, there are several places that affect USB: 1. external oscillator 16.9344 MHz 2. the upll locktime of the locktime register 3. upllcon 4. the upll switches of the clkslow register are excluded one by one: 1. the crystal oscillator is used by mpll and upll. It has never been said that mpll is uns

. pclk is measured. This is output by sensor. It is normal (58 MHz, and the maximum value of Qualcomm is 96 MHz) and consistent with that configured in the register.5. Measure the H/V synchronous signal, which is output by the sensor and is normal. Consistent with FPS and resolution.6. measurement data signal, which is output by sensor and is normal. (Data signal, which can be seen on the oscilloscope)In this case, sensor is working normally, but why

used by other products, we can also find a lot of related design materials and related technical topics on the network, which further lowers the technical threshold, ensures the feasibility of using this processor for products, and reduces risks;On the contrary, if it is a new processor launched by the manufacturer, because there are no products available for reference in the market, we can only read the chip manual in full English to understand this chip, in this way, the development cycle is

Something nice In this example, the sine wave, triangle wave, sawtooth wave, and square wave waveform data are used as a reference to briefly describe SignalTap II.

Do not call the system clock, because this example uses the system clock as the sampling clock of the logic analyzer. (5) Add the system sampling clock (similar to the oscilloscope sampling) (6) set the sampling depth

that when you debug the screen, the video cannot be played, but the audio file has been unlocked, you need to consider whether the screen refresh command is each frame of the image needs to be sent, if yes, I am sorry no matter the cost of a large cost to send, or else there is no way to play, such as here himax8369-A, at present, it seems that we need to constantly refresh 0x2c to maintain the continuous display of the image. Currently, the method of sending a single brush for the static image
