![]() ![]() If there is a slave on the bus with the indicated address, it will respond Which determines if the master intends to write to or read from the slave. The address byte of the slave it intends to communicate with. To begin communication, the master device sends out a Start bit followed by I 2C operates with one or more master devices and one or more slave devices. The bare metal code is easier to follow,Īllowing a fast ramp-up on the use case associated code. Portability of code across different platforms. The Foundation Services generated code offers aĭriver-independent Application Programming Interface (API), and facilitates the Offers hardware abstraction layers that ease the use of the code across differentĭevices from the same family. Using Foundation Services Library, and one bare metal code. Mode writes to and reads data from an MCP23008 8-bit I 2C I/O expander (clientĭevice), addressed in 7-bit mode, using interrupts.įor each use case, there are three different implementations, which have the sameįunctionalities: one code generated with MPLAB ® Code Configurator (MCC), one code generated This example shows how the microcontroller configured in I 2C Host I 2C Client devices on the PICkit Serial I 2C Demo Board. Shows how the microcontroller configured in I 2C Host mode interacts with different The document covers the following use cases: PIC18-Q10 product families and intends to familiarize the user with the PIC ® This technical brief provides information about the MSSP peripheral of the PIC18-K40 and Master Synchronous Serial Port (MSSP) to the Stand-Alone For aĭetailed comparison between the MSSP and dedicated I 2C peripherals, refer to: Peripheral Interface (SPI) and Inter-Integrated Circuit (I 2C), having theĪdvantage of implementing both communication protocols with the same hardware. The MSSP peripheral can operate in one of two modes: Serial The MSSP and I 2C peripherals are serial interfaces useful for communicating withĮxternal hardware, such as sensors or microcontroller devices, but there are alsoĭifferences between them. ![]() PIC18-K83, PIC18-Q41, PIC18-Q43 and PIC18-Q84 product families have a dedicated While the PIC18-K40 and PIC18-Q10 productįamilies have a Master Synchronous Serial Port (MSSP) peripheral, the PIC18-K42, PIC18F device family of microcontrollers. The approach in implementing the I 2C communication protocol is different among the Author: Filip Manole, Microchip Technology Inc. ![]()
