Serial peripheral interface spi is one of communication protocol between master and slave device. Ftdi api for serial communication protocols spi, i2c. It visualizes the buses corresponding to the analyzed protocol and triggers on protocol events. For this example, see the bottom of file c in your mplab directory. An i2c protocol is one of the serial communication protocol that is used for the chip to chip communication. Place holder and title slides have been removed from this application note and place holder and title slides have been removed from this application note and some slides with all text have been incorporated into the application note speaker notes. We will remove access to the work immediately and investigate your claim. Serial communication protocols in embedded systems introduction to uart,i2c and spihindi duration.

In practice if these handshaking lines are used it can be difficult to set up the. I am working on fpga project where i have to configure the onboard ics with spi interface specified in their datasheets and few with the i2c interface. The spi bus is commonly used for communication with flash memory, sensors, realtime clocks rtcs, analogtodigital converters, and more spi serial peripheral interface. Can i use i2c protocol for product with spi interface ics. Spi can be very flexible and high speed have only 10. Interintegrated circuit i2c the i2c bus drivers are open drain meaning that they can pull the corresponding signal line low, but cannot drive it high there can be no bus contention where one device is trying to drive the line high while another tries to pull it low, eliminating the potential for damage to the. Similar to the i2c protocol, spi and uart also used for the chip to chip communication. The serial peripheral interface spi is a synchronous serial communication interface. The mpsse always acts as a master controller for the selected synchronous interface. The walkthough will explore code for both an spi master and spi slave. Common microcontroller communication protocols february 17 2015 mer421. Just select device serial protocol connection from polymorphic dropdown menu. I2c requires a mere two wires, like asynchronous serial, but those two wires can support up to 1008 slave devices. Generally the fewer the wires the more rigid the protocol.

Todays topics serial communication rs232 ttl serial spi i2c. Electronic communication protocols basics and types with. The protocol analyzer supports the following protocols. The ssi protocol employs differential signaling and provides only a single. In this video i show you more or less how i2c, uart and spi serial communications work. Communication protocols uart spi i2c how to use youtube. The spi bus can operate with a single master device and with one or more slave. It was developed by the robert bosh company in 1985 for invehicle networks. Also, unlike spi, i2c can support a multimaster system, allowing more than one master to communicate with all devices on the bus although the master devices cant talk to each other over the bus and must take turns using the bus lines.

Data, select and rw signals can share the same line, depending on the protocol. Usic peripheral of xc2287 microcontroller is used for spi protocol generation. The settings and controls for these analyzers are located in the tabs below the menu bar. It is based on a messageoriented transmission protocol. Rs232 rs232 is a standard for asynchronous serial communication. At the protocol level, the user can use specific data buffers with an optional automatic cyclic redundancy check or.
