spi bus protocol

When talking about protocols, many people always think about networks and computers first. Indeed, computers and networks are large users of Protocols. However, with the constant development of electronic technology, more and more fields are beginning to use electronic devices that are almost as intelligent as computers, which also involve Protocol issues. Now we will introduce the CAN bus

We have previously introduced the basic concepts of the CANopen bus protocol. Now we will take a look at the CANopen bus protocol equipment. First, let's take a look at the features of these devices through the following aspects. We will also know why CANopen bus is becoming

In the previous article, we have explained the basic concepts and related principles of the I2C bus protocol. I don't know if you have any knowledge. Now we will introduce this application. First, let's see which devices have the I2C bus protocol. I2C bus application At pres

Nowadays, many communication electronic devices are highly intelligent. To some extent, it is comparable to computers. In the communication settings, we will introduce the use of the CANopen bus. Considering that CANopen bus is a good open and low-cost Field Bus supported by most European and American manufacturers, it is necessary to enhance the study of CANopen

I'm confused about the I2C bus protocol? I was not quite clear when I first saw it. Let's take a look at the role of the I2C bus. Maybe this will give you a little bit of understanding. I2C bus application At present, many semiconductor integrated circuits have integrated I2C interfaces. Single-Chip Microcomputer with

1. FSMC Protocol Analysis The following is the protocol for the ILI9325 8080 interface It can be seen from the diagram that the protocol of the 8080 interface is: The first issue of the signal, and then issued a command to enable or data to enable the signal, after the completion of the data, in the reading and writing signal on the rise along the write data or

I2C bus protocol I2C bus protocol learning notes1. I2C ProtocolTwo two-way serial lines, one data line SDA, and one clock line SCL.The data transmitted by SDA is transmitted at a large end. Each transmission is 8 bits, that is, one byte.Multimastering is supported, and only one master can be created at any tim

SD bus protocol SD bus communication is based on commands and data bit streams. The Start and Stop bits end. SD bus communication has three elements: Command: the host sends the command to the card device and uses the cmd line to send the command; Response: sends data from the card end to the host end. as a response to
