IC bus line explains conduct and transmits the bus line as one kind, it uses and is wired little, simple in construction, it is the extensive high-performance bus line way of a application. The operating system that and Linux cuts out publicly and easily as a source code, is very suitable for the application of the embedded system. The embedded apparatus under Linux operating

system is driven, through IIC bus line, realize the collaborative work among ARM and peripheral module, there is extensive application. IIC I2C made up of two sticks of signal line: A two-way transmissive data link SDA; Another one is a clock line SCL. IIC bus line can realize half duplex synchronous data transmission through the simple structure. Adopt one main fact more than IIC bus line from operating mechanism, at one time can only have one of apparatuses as master, by main device control, main the intersection of device control and machine format the intersection of conveyance and initiating signal, send out clock signal, the intersection of slave and address signal, intelligence signal total collinear operation, the receive data side sends out the answer back signal while conveying finishing, the apparatus on each IIC bus has an only address, and the master carries on communication. IIC bus line sequence is shown as in Fig. 1, while IIC bus line uses, the start of transmission and condition stopped are as follows: As SCL sustains 1 ³ And SDA is from 1 Turn into 0 Show hour that will begin the transmission data; And sustain SCL 1 ³ And SDA is from 0 Turn into 1 Show that stops the transmission data. Among them the data on the SDA line are in the clock line SCL 1 ³ It must be stable during this time, only when the clock signal on the SCL line is for being low the state on the line of the data could...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
