It is obvious, a slice of SM2965 includes canonial 80C32, FLASH, E2PROM 28SF512, SRAM static data storage And WDT watchdog`s timer SM2965 is that the cost performance is extremely quite high The one piece Computer. And its ISP characteristic makes FLASH E2PROM can be regarded as the space of procedure, can also keep the data like E2PROM.Regard it as PLC that core design, have l

ow cost, be small, expand advantage convenient and flexible in usage. Regard microcontroller as the core and design PLC, it is basically the same that its hardware makes up and observes and controls the system as the microcontroller. But in the microcontroller observes and controls the system, examine And accuse of Course to be serial relation at time. And PLC according to circulate scanning mode, carry on work, include, input sample, program execution and export, break 3 stages each period of scanning period, the relation operating mode runs side by side in inputting, concentrated output to adopt concentrating on. If like the microcontroller observes and controls the system, gather the state of the leading-in terminal to the line of procedure of PLC ladder-diagram in real time sequentially, the real-time output after process, can not reach the control result of PLC. For this reason, set up, input, buffer as input the intersection of map and register in the intersection of RAM and district, adopt and at one time read in all leading-in terminal states, and store it in the input buffer, then, according to the logical relationship of the line of procedure of ladder-diagram, read the corresponding leading-in terminal state from the input buffer, operation stores the result to be outputted in the output buffer map register of the component after dealing with. Finally, finish all as the intersection of ladder-diagram and...
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.....
