is used, for example, if we transmit a five-digit red, then our M4-M0 bit is connected to the opposite side's P7-P3, the P0-P2 of the other party is connected to our M4-m2 (this can be verified by an oscilloscope ); For the above interface, each driver usually has a unified interface, for example: Open, close, ioctl, write, read, MMAP, of course, different drivers may only be implemented. For LCD drivers, the most important thing is open, ioctl, and

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!

BUG: A Part Of The programmer's life. They cannot leave each other and are not happy with each other. Maybe you have a wonderful life. Do you have any wonderful bugs? It has plagued me for almost two weeks. Let's just call it small A. Small A has never dared to face me, and she is escaping every day. Every time she passes by with it, she feels familiar with it, I also found that we are not familiar with it. Because of this, it can be proud for so long; and because of this, it can even get tired

; use ACM for voice compression and decompression; Use Winsock for network communication. The experimental program implements the basic functions of network voice transmission. The collection set and playback buffer in the program are of the same size, and the number is both 2. The experiment uses the ping-pong system. We have measured the relationship between the buffer size and the end-to-end latency in the Ethernet environment. The idea of end-to-end latency measurement is to run a program, i

damage, can not be repaired, Another point is that your BIOS file must be consistent with your motherboard model, including the manufacturer and model, otherwise the refresh will often cause the phenomenon of not showing. Motherboard point does not light maintenance example 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 b

parameters makes the code smaller, but the code loses some features, which is also a way to do it. Learning the impact of development boards Learn how to implement it Measuring measuring 1. The best instrument is an oscilloscope. 2. Test on the electrical start time, this is a very accurate way of testing. 3. It is very simple to write Gpio port and memory when the system starts. 4. Some oscilloscopes can afford it. 5. Usually you do not want to us

, short circuit. Next, use the oscilloscope (if not, only with a multimeter), measuring the power supply foot of the SD card seat. In general, the voltage value should be around 3.3V, if the difference is too large, may be a circuit error, or LDO power supply capacity is insufficient. If you confirm the above two steps, then the hardware is not a big problem. The next thing to confirm is the problem with the driver on the firmware. Generally speaking,

After reading the I2C official agreement document, take s3c2440 and EEPROM to verify it. Originally want to use s3c2440 SDA and SCL pin Gpio to simulate, but in the absence of an oscilloscope for a week, how can not come out, finally or give up. Even reference to Linux under the i2c-algo-bit.c and I2C-GPIO.C, Still not tuned out. If there is an oscilloscope, it may soon be possible to find the cause, and no

. RF chip in the use of OFDM modulation mode to send data, the entire frame is divided into different data blocks to send, in order to ensure the reliability of data transmission, there will be a GI between the blocks, so that the receiving side can correctly parse out the various data blocks. Wireless signal in the space transmission due to multipath and other factors on the receiving side of the formation of delay, if the subsequent data block sent too fast, and the previous data block formati
