The communication bus PM866A-2 is a programmable microcontroller, and communication with SPI is actually two independent things.
It’s just that we can use a microcontroller to achieve SPI communication, but achieving SPI communication does not necessarily require a microcontroller.
We need to communicate with each other through speaking, and both people should speak the same language, such as Mandarin.
How can chips communicate with each other, but they don’t know how to communicate?
It is through the communication bus. There are many types of communication buses, such as IIC, SPI, USART, CAN, and their differences are similar to Mandarin, English, Korean, and Russian, which are all used to transmit information, but the transmission methods are different.
But there is a prerequisite for transmitting information, which is that the language must be the same, that is, the communication method must be the same.
So, SPI is a communication method used to transmit information.
Different PM866A-2 methods result in different ways of transmitting information.
Spi is a full duplex, high-speed, and synchronous communication bus.
Simply put, it means that the two of you can speak quickly at the same time, tell each other what you want to say, and also hear what the other person is saying. This is full duplex.
There is another type called half duplex, which means that you can only have one person speak at the same time, the other person listens, and after speaking, the other person can speak.
It is obvious that full duplex PM866A-2 of information is more efficient.
The meaning of synchronization is that I set a condition for both of you to have a conversation. For example, if I say you can have a conversation only when you start, or if I say you stop, you cannot speak.
