This article has compared all three communication interfaces, including their advantages, disadvantages, and uses.
communication within the system Devices communicating with each other on a serial bus must have some form of protocol which avoids all possibilities of confusion data loss and blockage of information Fast devices must be able to communicate with slow devices The system must not be dependent on the...
It adds a protocol layer on-top of basic I2C communication and has a series of more complex tests. advanced_slave - this creates a Slave device which responds to the advanced_master sketch. It responds to a protocol layer on-top of basic I2C communication. advanced_scanner - this ...
1. What is the full name of SPI? SPI, is the abbreviation of Serial Peripheral interface, a high-speed, full-duplex, synchronous communication bus. 2. What is the difference between UART and serial port? UART is a serial port, but the serial port is not necessarily UART, ...
voidI2C1_Init(constunsigned longclock) :- The first thing we need to do is the initialization of the MSSP module for I2C communication. This can be done withI2C1_Initfunction. e.g.I2C_Init(100000)will configure the MSSP module for I2C communication at 100 KHz. ...
Note: Here's when you should Really Not Use I2C: I2C is only design for communication on a single PCB - do not use it as a Local Area Network - some have tried - all have failed! For long distance use RS422 etc.With this background on the I2C protocol fundamentals, you should now...

6. LED1-3 blinks when communication is ongoing. Also, if semi-hosting is uncommented in i2c_hal_slave_functions_mg.h, the output can be viewed in Debug Console window (see figure). Touching the touch screen causes values of the received data in the console to change. . Figure 5. ...
The I2C communication component answers with 0xFF until a valid response is passed by the bootloader. After receiving 0x01, the host must perform another read to get the remaining N – 1 bytes of the response. After both reads are complete, the results are combined to form the full ...
One advantage of I2C over a communication standard such as SPI is that it has a built-in communication protocol that allows easy, error-free communication between devices. The Cypress PSoC 1 device offers several choices for implementing I2C in a design. These choices come in th...
