spi can bus

What is SPI The SPI is the service Provider Interface, which provides the interface. SPI thought Abstract in our system of the various modules, often have a lot of different implementations, such as the program of the log module, XML parsing module, the JDBC module scheme. In the object-oriented design, we generally recommend that the modules are base

1-Wire Bus Technology and Its Application Abstract: This paper introduces the principle and signal transmission mode of the single bus technology introduced by Dallas, and describes the single bus communication protocol, finally, the single-bus data transmission method is presented based on the application of the si

widely heard. for programming in Linux or windows, the addresses operated by the program are all virtual addresses. Virtual Address is a combination of hardware MMU and Software Memory Management to facilitate more efficient use of RAM. Memory Management is a big article. I will not talk about details here. For details, refer to the memory addressing chapter of utlk. Logical Address virtual address can be operated by software developers Based on System Programming and bare coding. 3. physical

1. SPI (serial peripheral interface of serial peripheral interface): high-speed, full-duplex, synchronous serial port.Three or four signals are used for data exchange:Simo: Inbound and OutboundSomi: Inbound and OutboundUclk: the clock, which is driven by the host and used by the slave to send and receive data.Ste: Allows sending from the slave machine. It is used to control multiple slaves in multiple Master/Slave systems in four-line mode. Three-line

The S3C2440 contains two serial peripheral device interfaces (SPI ports), each of which has two 8-shift register for sending and receiving, respectively, in one SPI communication, data is synchronously sent (in serial mode) and received (in serial mode ). The rate of 8-bit serial data is determined by the content of the relevant control register. If you only want to send data, some virtual data will be rece

1. IntroductionThe SPI full name is the service Provider Interface, the provider interface, the service usually refers to an interface or an abstract class, the service provider is a concrete implementation of this interface or abstract class, by the third party to implement the interface to provide specific services. SPI provides a dynamic mechanism for extending applications, often as an extension of the

I2C (Inter integrated circuit, internal integrated circuit) bus is a very inexpensive and efficient network for interconnecting peripherals in small, embedded systems. The I2C bus is sometimes called IIC, which has a history of more than more than 20 years. The I2C interface and the SPI interface work the same, but the two methods are different. 　　 The I2C

The business logic implemented using the policy pattern is more flexible and is often used as a substitute for conditional statement blocks in programming. And the SPI mechanism is in fact simi
