What are two methods of communication between the microcontroller and the external device?

Serial Peripheral Interface (SPI), Inter- Integrated Circuit (I2C), Universal Asynchronous Receiver / Transmitter (UART), Controller Area Network (CAN) and Universal Serial Bus (USB) are ideal communication protocols which people use for communication between microcontrollers.

CAN bus communication between two microcontrollers?

A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer.

What is microcontroller communication?

It is a serial communication of a two-wire protocol. The data cable signal lines are labeled as Rx and TX. This protocol is used to transmitting and receiving the data byte by byte along with the clock pulses. Different devices communicate with microcontroller to this protocol.

What are types of communication protocols?

Types of Protocols

• Transmission Control Protocol (TCP)
• Internet Protocol (IP)
• User Datagram Protocol (UDP)
• Post office Protocol (POP)
• Simple mail transport Protocol (SMTP)
• File Transfer Protocol (FTP)
• Hyper Text Transfer Protocol (HTTP)
• Hyper Text Transfer Protocol Secure (HTTPS)

What are the different communication interfaces?

There are three types of communication interfaces (RS-232C, RS-422A and RS-485) available between the AL3000/AH3000 recorders and personal computers (PCs). PCs can be used to receive measured data from the AL3000/AH3000 recorders, program different parameters and issue control commands.

What is communication circuit?

What Is CAN? The Controller Area Network (CAN) is a serial communication bus designed for robust and flexible performance in harsh environments, and particularly for industrial and automotive applications.

What is communication protocol and its types?

A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. Protocols may be implemented by hardware, software, or a combination of both.

What are the two types of communication protocol?

Types of Communications Internet Protocols (IP)

• Transmission Control Protocol (TCP) – used for data transmission.
• User Datagram Protocol (UDP) – used by programs to send short datagram messages.
• Internet Control Message Protocol (ICMP) – messages used for diagnostic or error-generating purposes.

How many types of computer communication are there?

There are three different types of telecommunication and computer networking channels to be aware of: simplex, half-duplex, and full-duplex.

What are mixed signal microcontrollers and how do they work?

By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.

How to communicate between multiple MCU’s?

The solution I’m imaging right now would be to do basic communication between near MCUs by GPIO or RS-232 (cheap!) and use Ethernet / ZigBee / Wi-Fi on one MCU per “zone” to communicate with the server (expensive, but it is still a lot cheaper than one Ethernet module per each client MCU).

What is the use of microcontroller in IoT?

In the context of the internet of things, microcontrollers are an economical and popular means of data collection, sensing and actuating the physical world as edge devices. Communication between two micro controllers can be possible using wired and wireless protocols.they are given in below table

What are microcontrollers used for?

Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
