In addition, IIC (Inter-integrated circuit) is simply abbreviated as IICBus, so chinese should be called an integrated circuit bus, which is a serial communication bus using a multi-master-slave architecture, developed by philips in the 1980 s for connecting a motherboard, an embedded system, or a mobile phone to low-speed peripheral devices. The correct reading for IIC, I2C, is "I-squared-C", and "I-di-C" ("I-two-C") is another erroneous but widely used reading. From 10/1 of 2006, no royalties have been paid using the I C protocol, but the manufacturer still has to pay to obtain I C slave device addresses.
The I2C serial bus typically has two signal lines, one for a bi-directional data line SDA and the other for a clock line SCL. All serial data SDA connected to I2C bus equipment are connected to SDA of the bus, and clock line SCL of each equipment is connected to SCL of the bus.
To avoid confusion of the bus signals, the devices are required to be connected to the bus output either as an open-drain (OD) output or an open-collector (OC) output. The serial data line SDA interface circuitry on the device should be bi-directional, with output circuitry for sending data onto the bus and input circuitry for receiving data on the bus. The serial clock line should also be bidirectional, and as a host for controlling bus data transmission, on one hand, a clock signal is sent through an SCL output circuit, and on the other hand, the SCL level on the bus is detected to determine when to send the next clock pulse level; as the slave receiving the command from the master, the slave may send or receive the signal on the SDA according to the SCL signal on the bus, or send a low signal to the SCL line to extend the period of the bus clock signal. When the bus is idle, the pull-up resistor Rp keeps the SDA and SCL lines at high level because each device is an open-drain output. The low level output by either device will cause the corresponding bus signal line to go low, that is: the SDA and SCL of each device is also in an AND relationship.
The bus has no special requirements on the manufacturing process and level of the device interface circuit (both NMOS and CMOS can be compatible). The data transfer rate on the I2C bus can be as high as ten thousand bits per second, and in high speed mode over forty thousand bits per second. In addition, the number of devices allowed to be connected to the bus is limited to a capacity of not more than 400 pF.
The operation of the I2C bus (data transfer) is controlled by the host. The host is a device that starts data transfer (sends a start signal), sends a clock signal, and sends a stop signal when the transfer is completed. The devices visited by the master are called slaves. For communication, each device connected to the I2C bus has a unique address for host access. The data transmission between the master and the slave can be realized by sending data from the master to the slave or sending data from the slave to the master. Where a device that sends data to a bus is called a sender, a device that receives data from the bus is called a recipient.
The I2C bus allows for multiple microprocessors and various peripherals to be connected, such as memory, LED and LCD drivers, a/D and D/a converters, etc. In order to ensure that data is reliably transferred, the bus can only be controlled by a certain host at any time, each microprocessor should send start data when the bus is idle, and in order to properly solve the problem of the conflict of the transfer (bus control right) of starting data sent by a plurality of microprocessors simultaneously and deciding which microprocessor controls the bus, the I2C bus allows devices with different transfer rates to be connected. The process of synchronizing clock signals between multiple devices is called synchronization.
Finally, it should be noted that each functional device in the embodiments of the present invention may be integrated into one processing device, or each device may exist alone physically, or two or more devices may be integrated into one device.
The functions, if implemented in the form of software-enabled devices and sold or used as a stand-alone product, may be stored in a computer-readable storage medium. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
