1. UART Communication Exception 1.1. PhenomenonFriday debugging CSR8670 encountered a serious problem: in the Xide environment debugging, CSR8670 received the data from the MCU will respond normally. Once running offline, the communication between CSR8670 and MCU is abnormal, which is as follows: The MCU sends an X-byte command to the Csr8670,uart task to receive a command that is less than X bytes long and the number of bytes sent first is lost The MCU sends multiple X-byte command

This post collect all the Foxwell gt80/gt80 Plus questions and engineer answers from Foxwellshop customers, hope It enlighten others who is interested in the this tool. BTW, Foxwell GT80 and GT80 Plus share, the same function and vehicle coverage, the only difference is GT80 is a built in with Battery and with a different-a half price.Questions about function:Question:The GT-80 Plus has TPMS program functions?? Also its capable to update by itself via Interner and Foxwell has

the stepper motor two-phase lead to the double-trace oscilloscope input, and then find a motor with a rotating shaft (I am using a hand drill to clamp the motor shaft, my hand drill can be positive and negative). To maintain a stable speed, you will see the above image on the oscilloscope: two-way fixed perfect sine wave, when the speed increases when the amplitude and frequency changes (linear relationshi

oscilloscope and a multimeter to see what happens with each pin.The oscilloscope is now used to verify the specifics of each pin: 1.gnd-fixed at 0V so it must be grounded. 2.Tx-You can see the information sent in the picture 3. Fluctuations between 0v, then must be Rx, that is because there has not been a larger float. Now that we have understood the pin situation, the following need

, if your mind is all on this, then you will be doomed to become a Kong Yiji type of characters! Enough, because technology is only one of the pillars of your future, and not the biggest pillar, unless you are only willing to old and an engineer![3] Do not do technical master, only to do comprehensive quality master! In the enterprise mix, we often look down on someone, said he "do not understand anything, why take so much money, with what promotion!" "It's a cliché of the typical engineer of th

willing to be an old engineer! [3] Do not be a technical master, but a general quality master! When we are in a company, we often look down on someone and say, "I don't know anything. Why do we get so much money and why do we get promoted !" This is a common example of engineer pedantic. Is 8051 awesome? People must have his skills, and you cannot. Do you think the boss has been operating for so many years? People may be good at management, understanding the boss's intentions, and department

To facilitate understanding, the waveform is the signal from the infrared receiver, which is the opposite of the signal level (0 or 1) described in the Protocol. The NEC protocol is one of the many infrared remote control protocols. In addition to NEC, there are other protocols such as RC5 and rc6. Most of the non-learning universal TV remote control devices I bought on the market integrate one or more codes of the NEC type. Three or more codes of the two remote control devices I bought are n

Summary of debugging process and method of camera driver Based on the previous debugging of the camera driver, I have summarized some minor experiences: 1. Check whether the camera circuit connection is correct based on the circuit diagram; 2. Use A multimeter to measure the power supply pin of camera and check whether the power supply of camera is normal.ProgramFor power control; 3. Check the spec document of camera and check whether the pin triggering of pwdn and reset is normal and whet

Computer motherboard fault Judgment method: First, check that the wiring on the motherboard is intact. Get a motherboard to see if there is any damage to the surface, if you please repair the line. Check all capacitors, especially the processor voltage regulator filter capacitor and memory card slot voltage Regulator capacitor has no drum kit (see directly) and leakage breakdown (must use universal table). Then, the smell of a component in the absence of power in the case of a burnt paste flav

The motherboard does not light maintenance methods: Example 1. A pci1600-f motherboard is not lit. First of all, visual inspection, found that the Power control IC U24 (AIC1569) surface has burned traces, welding U24, check the peripheral circuit did not see abnormal. The board returned to normal after replacing the U24. According to the user reflects this problem is more common, AIC1569 purchase is more problematic, I found from the data can be used HIP6004 directly substitute it. Example 2.

Offline browsing refers to the computer reading the contents of a Web page when there is no internet connection. As a result, users can access a Web page directly by setting it offline so that they don't have to worry about dropping the line and browsing the web. The way to browse a Web page offline is to click File Work offline in the menu bar when you visit a Web page, as shown in the following illustration. (Oscilloscope and

Just got the new board, the program burned in, but the wrong run address, did not enter the C language Did not enter the C language, there may be hard dog problems, to remove the hard dog Check the following four cases 1. Check the chip power supply is all right2. Check if the crystal oscillator line is shorted3. Check that the load capacitance is correct4. Check that your reset circuit components are correct Viewing the crystal oscillator with an oscillo
