Is Raspberry Pi able to use the serial port? The answer is yes. The specific method is as follows: 1. The third, fourth, and fifth ports in the first row of Raspberry Pi are respectively, that is, ports 6, 8, and 10 are respectively, TX and RX, respectively, and connected to the connected device. Note that the TX of Raspberry Pi is connected to the RX from the device, and the RX of Raspberry Pi is connected

Based on the protocol encapsulation of the serial port through commconnection, the mechanism of synchronization is adopted. The general process is as follows:Sending commands --- reading and responding to data cyclically; this operation is very simple. When there are a large number of interactions or the state machine is used, the Code is a large loop and a small loop, and the structure is not good, I want

Linux under the serial port programming articles online is flying, but mostly from an article, and write are some basic operations, such as control rts/cts, such as serial pin state, receive send binary data and so on, there is no good explanation, I encountered some problems in use, write out, I hope to For everyone to help, less detours, hehe. The operating sys

data transmission. Asynchronous mode means that data can be directly sent without a clock line during data transmission. For example, we often say that serial ports adopt asynchronous methods. There is no clock signal line between the sender and receiver. They use their own clock. After understanding synchronization and Asynchronization, continue to look at UART. We can think of it as a thing integrated into the microprocessor, which consists of two

It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about driver knowledge. While studying other people's code, you must also do it yourself. The following is a serial
