message segment on these networks, and decide how to package the information into a message domain and how to decode it.Modbus messages on other networks (such as map and Modbus plus) are converted into frames unrelated to serial transmission.1. ASCII modeWhen the controller is set to communicate in the Modbus network in ASCII (American Standard Information Exchange Code) mode, each 8-bit byte in the message is sent as two ASCII characters. The main advantage of this method is that the interval

G711 Encoding G711It is an international Telecommunication Union ITU-T Custom-made set of speech compression standards, which represent the logarithmic PCM (logarithmic pulse-code modulation) sampling standard, mainly used for telephones. It mainly uses the Pulse code modulation to the audio sampling, the sampling rate is 8k per second. It uses a 64Kbps uncompressed channel to transmit voice signals. The compression rate is 1:2, which is to compress 16 bits of data into 8 bits. G.711 is the ma

can be used as a host (called Master), other devices as slaves (called slaver), the host does not need to number, slave must be numbered. The protocol defines the format of the information frame of the host query and the slave response. Paper Daquan. When communicating, the host first sends the request information to the slave, receives the communication command according to the corresponding address code, and removes the address code, reads the information, if there is no error, executes the c

The main advantage of this approach is that the character can be sent at a time

, which makes normal embedded patches more difficult. Now that you understand the principle of shell, you need to understand the principle of embedded patch. The problem is similar: Q: What is an embedded patch? A: Embedded patching is a technique that removes the need to shell a program! Q: How does it work? A: To do this, we must insert a piece of code after the original code of the program is written in the shell code and before the application to be modified. One of the most important issu

5.3.2 cyclic redundancy check and error check plan The parity check code (PCC) introduced in the previous section can only verify one error. The cyclic redundancy check code (CRC) described in this section has higher error checking capability and can detect multiple errors.1. CRC Verification Principle The CRC verification principle seems complicated and difficu

Attachments are often a series of compressed files, the download is the default filename is a random number. As a result, compressed file decompression failed after downloading Workaround: Rename the file name with a certain order when downloading, such as file 1, file 2, file 3, etc. How do I resolve a single file decompression failure? A lot of information in the forum is compressed using RAR, upload to download, in the process of decompression may occur errors. The most common occurrence

layer. C, if the escape character also appears in the data, then an escape character should be inserted before the escape character. When the receiving end receives two consecutive escape characters, it deletes the previous one. 3 Error detection Bit errors can occur during transmission: 1 May become 0 and 0 may become 1. Over a period of time, the ratio of transmission errors to the total number of transmitted bits is called BER ber (bit error rate). In order to guarantee the reliability of da

for I²C bus and other systems". The converter ends up with the pull-up resistor required by the I²C bus.Functional commissioning1. During the Si7021 measurement process, you can choose to have the SCL pull down (hold Master mode) or not to respond to the message from the MCU (No to master mode).2. The relative humidity measurement includes the temperature measurement, and the temperature measurement can be carried out separately.3. For relative humidity or temperature measurement, whether the M

data storage and data communication, the CRC verification utility library has to adopt the method of checking errors to ensure data correctness. Among the many error detection methods, CRC is the most famous one. CRC is short for Cyclic Redundancy verification. Its features are: high error checking capability, low overhead, and easy to use encoder and detection

It makes sense for everyone to use it. I just downloaded it for collection! ... After testing, all files uploaded to the nano disk are correct!The MD5 and sha1 verification codes are incorrect, basically because of problems arising during the download process. It is reasonable to say that the nano di

on when a becomes empty. partition movement between nodes does not need to stop the service, so adding nodes, removing nodes, or changing the number of partitions on a node does not require stopping the Cluster service. when a client accesses a cluster, it can theoretically access any node in the cluster. At this point, the data being accessed may not exist in the node being accessed, but the Access node can automatically know the target node, redirect the client's access, and return the destin
