Protocols in embedded systems is used to transmit/ Receive data from one device to another device. Controls the LED/LCD displays in cell phones, Helps switching on /off the power supply of internal components, Apply for communication with temperature, pressure sensors, and video game controllers, Supply power to the connected devices if applicable, Connect peripheral devices such as keyboards, mouse, printers, etc. Communication Protocolsfor Embedded Systems SPECIAL CONSIDERATIONS FOR EMBEDDED APPLICATIONS. 48 0 obj
This device sends and receives data from one system to another system. You see a device that you need in your system, it uses protocol "blyfix", so we see if we can implement protocol "blyfix". Changes the various color setting, such as hue, on a monitor. 61 0 obj

It also depends on required speed of transmission, environment it is operating in, what is currently in use for devices in place, what modules are available for controlling processor. (Properties)
(Definition of a protocol)
UART (Universal Asynchronous Transmitter Receiver), this is the most common protocol used for full-duplex serial communication.It is a single LSI (large scale integration) chip designed to perform asynchronous communication.
