I2C1 Module

The I2C1 module provides a hardware abstraction layer for the I2C communication protocol on Microchip PIC16F series microcontrollers. It includes functions for initializing the I2C module, sending and receiving data, and handling start/stop conditions in master mode.

I2C1 Interface #

The I2C1 interface provides a set of functions for I2C communication in master mode. Here is the list of functions in the updated I2C1 interface from the files you provided:

Functions in the I2C1 Interface #

  • void Initialize(void)
    • Initializes the I2C1 module in master mode, configuring the clock and setting up the I2C pins.
  • void WriteStart(void)
    • Sends a start condition on the I2C bus.
  • I2C_Status_Enum_t WriteAddress(uint8_t address, I2C_Address_Mode_Enum_t address_mode)
    • Sends a 7-bit slave address on the I2C bus, with a read or write bit appended, and checks for acknowledgment.
  • void WriteStop(void)
    • Sends a stop condition on the I2C bus, signaling the end of communication.
  • I2C_Status_Enum_t WriteByte(uint8_t data)
    • Sends a single byte of data on the I2C bus and checks for acknowledgment from the slave.
  • I2C_Status_Enum_t WriteBlock(uint8_t *datablock, uint8_t data_length)
    • Sends a block of data (multiple bytes) to the slave device and checks for acknowledgment.
  • uint8_t ReadByte(void)
    • Receives a single byte of data from the I2C bus.
  • I2C_Status_Enum_t ReadBlock(uint8_t *datablock, uint8_t data_length)
    • Receives a block of data (multiple bytes) from the I2C bus.
