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.

Some time ago, I debugged the mcp2515 driver in Linux. The driver basically passed the debugging. Some problems occurred when I debugged several other boards in the past two days. 1. When Linux is started, probe mcp2515 sometimes fails, sometimes succeeds, and some boards can always be successful. When the probe fails, the message "mcp251x didn't enter in conf mode after reset" is displayed ". Debugging analysis: During probe, the driver reset mcp2515 adopts the SPI command reset form, and the

written, you can use an oscilloscope to directly measure the clock to see if it is the number you configured, the next step is to test the memory. This test must write a simple small program. In fact, it is mainly to test whether the data bus works normally. If there is a problem when configuring the minimum system, there are two common problems, first, the register is incorrectly configured. The solution is to combine examples and engineerTo enginee

Part of oscilloscope Development The dynamic link library of zlg is used for dynamic loading. Arm is Context-M3-1343. PC communication software developed in C ++ Builder 6. The USB communication code is as follows: // ----------------------------------------------------------------------------- For details, see www.jxust3jia1.com, which describes the oscilloscope project.

is not a problem at all. Frequent turbulence is not the best strategy. In the end, you are not thoroughly aware of any industry. It is always a newbie! This is an important part of software engineer career planning. You can do technology, and never indulge in technology. Never go into technology with one mind! Put a lot of pressure on yourself. If you put all your thoughts on this, you will surely become a character like Kong Yiji! That's enough, because technology is only one of the pillars of

When using the STC single-chip microcomputer, do you encounter a problem: the delay is often difficult to grasp. Of course, you can use the latency function to generate waveforms and output them to the oscilloscope for observation to modify the latency parameters. However, there is no way to determine the latency parameters when there is no oscilloscope. I have created a method here to share it with you.In

called, it is not true. Why is it related to the clock speed ?? Check the hardware. Hardware circuit: In fact, it is part of the matrix key scanning circuit. Several GPIO ports are connected with the line signal, and several GPIO ports are connected with the column signal. After simplification, for example, the IO port of the column signal is set to output 0, and the corresponding row IO port is set to pull-up input. Once you press the key, there will be a descent along the hop on the IO port.

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 coordination. Therefore, we must develop our own capabilities in many aspects, including management, affinity, observation, and research capabilities. To become a master of comprehensive quality, we have no way to go. Otherwise, we can only look at the

can only look at the oscilloscope in the corner! Skills other than technology are more important !! From ancient times to the present, the United States and Japan are all like this!

If you want to be a boss or a senior manager one day, these are the people you face throug

Use an oscilloscope to check whether data is received by the receiving pipe foot; 3. baud rate problem-whether the communications port is consistent; The received data is incorrect because: 1. it may be whether the external clock is used correctly.

Error)Error = FN (Dev, data );These two statements are loaded with four serial drivers in sequence. The FN here is the _ driver_attach function of the outer layer... Now that we have found the place to load, we can use printk to find that this loop is only performed twice. That is to say, only serial 0 and Serial 1 are loaded. This indicates that there are only two

time sequence is correct: In the earliest stage, whether it is from the lpcflash or spiflash, the CPU is actually executed according to the time sequence specified in the LPC and SPI protocol specifications. To eliminate timing problems, you can capture the corresponding clock signal through the oscilloscope and control the signal to analyze whether the waveform is a symbol timing requirement. Observe whether the crystal oscillator of the CPU, memor
