Registering a SDIO driver will call the following function: /*** Sdio_register_driver-register a function driver* @drv: SDIO function Driver*/int sdio_register_driver (struct sdio_driver *drv){Drv->drv.name = drv->name;Drv->drv.bus = sdio_bus_type;Return Driver_register (DRV->DRV);} In fact, very good understanding sdio_driver is actually driver encapsulation, and the driver bus for Sdio_bus_type. The drive of this device is very simple. Look at the s

I2C (Inter-IntegratedCircuit1 bus is a 2-line serial bus developed by Philips, used to connect 1 Introduction I2C (Inter-Integrated Circuit1 bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. It is a special form of synchronous communication. it has the advantag

　　The D-Bus method is very important in mobile phone operating systems, including Linux-based operating systems such as Maemo and Moblin. It is estimated that Andriod is also widely used. For more information about D-Bus, see http://www.freedesktop.org/wiki/Software/dbus. , There are a lot of learning materials on the Internet, in http://blog.chinaunix.net/u3/111961/ There are a lot of Chinese materials and

I²C architecture is divided into three parts: I²c core, bus drive, device driverI²c Core :I²c Core provides a set of interface functions that do not depend on hardware, and the I²c-bus driver and device driver depend on the core of I²c as a link.(1) Add/Remove I2c_adapterint I2c_add_adapter (struct i2c_adapter *adap);int I2c_del_adapter (struct i2c_adapter *adap);(2) Add/Remove I2c_driverint i2c_register_dr

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The externa

Each device on the IIC needs an address register to determine its own address. Each device on the IIC needs an address register to determine its own address: Many devices are used to determine the address by hardware.Some in the factory when the address is set up, the user can not change, some identified several, the remaining several by the hardware to determine (for example, there are three users determined by the user, leaving 3 control address of the pin), this class more; There are address

Even after four years of study in Wuhan, I feel that Wuhan is incomparable with Beijing in many aspects, such as city construction and quality. However, there is one aspect that Beijing envy, that's the speed of public transportation in Wuhan! Even when I see traffic congestion in Beijing, I miss it even more ......Take the bus 521 and catch up with another 521. At that time, some people reminded us to pay attention to safety. As a result, the driver

I2C has never been touched before, so its simulation function can only rely on the feeling, there is something wrong, still hope that the House correct. With the SPI-related simulation function, it is not difficult to do I2C, but it is a little troublesome for users to read and write data through the I2C bus.Test program running interface: the I2C bus code in the simulator is as follows: public class i2ccom

The last time I talked about a client that was writing a RABBITMQ-based message bus in the face of concurrency problems and the final implementation of the solution. It's a simple and not prone to concurrency problem scenario, and if you read that article, I've given the pros and cons of the final implementation scenario.The core issue is whether client-created connection with RABBITMQ server is shared or exclusive. One more popular example of this pr
