How to communicate between two microcontrollers?
There are multiple different ways to communicate between microcontrollers. You could go the cool wireless route: Bluetooth, ZigBee, WiFi. Or throw some cables in the mix and use any number of established protocols: I2C, SPI, UART, all with their advantages and disadvantages.
What is parallel communication in microcontroller?
In data transmission, parallel communication is a method of conveying multiple binary digits (bits) simultaneously. Parallel communication is and always has been widely used within integrated circuits, in peripheral buses, and in memory devices such as RAM.
What are possible ways to communicate between two microcontrollers?
One or more UART peripherals are commonly integrated in microcontroller chips . USB was designed to standardize the connection of peripherals like keyboards, pointing devices, digital still and video cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power.
How are microcontrollers used in the Internet of things?
Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. 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.
What do you need to know about wireless controller?
Consequently, the most important component needed is the “connection and communication” module that enables the remote interaction between the device and “the community” via internet. Here we will sum up the various possibilities you can use to connect your controller using different wireless protocols.
How does the mrf24j40ma wireless transceiver module work?
The MRF24J40MA module connects to hundreds of PIC® microcontrollers via a 4-wire SPI interface and is an ideal solution for wireless sensor networks, home automation, building automation, and consumer applications. 2.4GHz IEEE 802.15.4 Transceiver module supports ZigBee™, MiWi™, and MiWi P2P protocols
