A computer to run the software Programming using the I2C header files: Now that we have learnt how an I2C communication works and how we can use the header file created for it, let us make a simple program in which we will use the header file and write some values to the I2C lines. This module also supports I I2C communication that is a two-wire communication. If the pins TX and RX (RC6 and RC7) are used by an other application we can use software UART. For PIC Microcontrollers which don’t have an SPI module or if any input/output either than the default hardware pins are required, the Software SPI functions can be used. The bus has a multimaster structure where each device on the bus can send or receive data. Bit 5 SSPEN: Synchronous serial port enable.Setting this bit enables the MSSP module for using in SPI or I 2 C mode. SPI_ACTIVE_2_IDLE = 0b00000000.
