Electronics hints, what will it welcome you to know basics of the microcontroller? Always try a little differently. Thank you for watching this video. Please like, share and subscribe to this YouTube channel, receiving more electronics information. Kindly suggest you a valuable feedback to improve the forthcoming videos. Thank you. The microcontroller is a complete micro-processor system built earlier, single integrated circuit. It is designed to perform a specific function in an embedded system. The microcontroller has CPU, memories, IOPOs, timer account, ADC, DAC and etc. Simple block diagram of microcontroller is shown below. CPU, this is the heart of the microcontroller. The micro-processor has ALU, registrars and control unit. The ALU unit performs the arithmetic operations like R, Subtract, R, etc. and logical operations like R and XR. Memory, the micro-processor has room and RAM memories. Room is a memory that cannot be changed via program or user. Room retains its memory even after the computer is turned off. For example, room stores the instructions for the computer to store the unit is turned on again. RAM is a first temporary type of memory in which programs, applications, hang data are stored. Examples of memory, hard disk, USB flash drive and etc. Input output ports. The IOPOGE allows the microcontroller to be connected with peripheral devices. The ports are bi-directional. The ports consist of a latch, an output driver and an input buffer. Timings are used to generate accurate time delay or can be used as external counter. Unlocked digital converter. This converts the analog signal to digital signal. Serious input output. The serial IOPO is actually two separate registers. A transmitter buffer register and a receiver buffer register. Buses. The microcontroller has three buses. Data bus. It is a bi-directional bus. The length of the bus depends on the word length. Address bus. It is an even directional bus. The length of the bus depends on the memory locations. Control bus. It is even directional. The length of the bus depends on the length of the un-control signal. Working of a microcontroller. The microcontroller is embedded inside a system to control a singular function in a device. It does this by interpreting data, it receives from its input output peripherals using its central processor. The temporary information that the microcontroller receives is stored in its data memory. The processor accesses it and uses instructions stored in its program memory to dissipate and apply the incoming data. It then uses its input output peripherals to communicate and re-enact the appropriate action. Applications. Some of the applications of 80-55 microcontroller or mentioned below. Consumer appliance, home applications, communication systems, office, automobiles, medical, defense, industries and etc. Features of microcontroller. The chip has CPU, memory, parallel and serial ports, interact controller, timer or counter, analog to digital and analog converters. It has numbers of registers, pins or programmable. It has number of bit handling instructions. It can function as a computer, high-speed operation. It can operate boolean function, it chip and occupies less space. Adventurers of microcontroller. The long-time record for performing the operation. It is easy to use troubleshooting and system maintenance is simple. At the same time, many tasks can be performed so that human effect can be saved. The process of chip is very small and flexibility occurs. Due to the high integration, cost and size of the system is reduced. The microcontroller is easy to interface, additional RAM, home and input output. Once microcontroller is programmed, then they cannot be reprogrammed. Without any digital parts, it can act as a microcomputer. It is easy to use troubleshooting and system maintenance is simple. Disadventures. It is generally usually micro equipment. It has a more complex structure as compared to micro processor. The microcontroller cannot interface here, how you power device directly. It only performed a limited number of execution simultaneously. Thanks to Google and Books. Kindly generate the mistakes in the video. Thank you for your visit to this channel.
