The I²C or Inter-Integrated Circuit is a serial communication and allows multiple devices to communicate with a micocontroller(s) over only two wires. The devices don't have to be identical as long as they support I²C protocol. In our illustration, the first device with address 1 is a digital temperature sensor, the second one is a real time clock and the third one is a serial LCD display and the bus could carry on even more devices. Communication takes place from the master (PIC) to the individual selected slave only as shown in this illustration. Configuration with PIC18F Peripheral Libraries and MPLAB Code configurator are discussed in this article

The DS1307 is a low power serial real time clock/calender with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static RAM. The RTC provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100. It can operate either in 24-hour format or 12-hour format with AM/PM indicator. Data and Address are transferred serially through a bidirectional I2C bus. DS1307 comes with built-in power sensing circuit which senses power failures and automatically switches to back up supply. Timekeeping operation continues while the part operates from the backup supply. The DS1307 RTC uses an external 32.768kHz Crystal Oscillator and it does not requires any external resistors or capacitors to operate.

Real Time Clock and Calendar functions are very important in many projects especially in data logging devices where a real time stamp is required in each record. This clock uses the DS1307 which is a low power serial real time clock/calender with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static RAM. This chip provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100.

The PCF8583 is a small 8-pin clock and calendar chip from NXP Semiconductors with full binary coded decimal (BCD) clock/calendar plus 2048 RAM (256 by 8 RAM memory) that is used in microcontroller based systems to provide real time date and time information. Data and Addresses are transferred serially through a bidirectional I2C bus. The PCF8583 RTC provides year, month, date, hour, minute and second information. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware

The MPLAB® Code Configurator (MCC) is a user friendly Graphical User Interface (GUI) plug-in tool for MPLAB® X IDE which generates easy to understand C code that is inserted into an MPLAB® X project, based on the settings peripherals configurations and selections made in the Graphical User Interface (GUI). The generated code can be used in any application program. When starting out with a new project using Microchip 8-bit microcontrollers, setup of the configuration and all the peripherals can be time consuming, especially for new projects. The MPLAB® Code Configurator simplifies this down to a series of simple graphical selections from the menus within the MCC.

TC74 is an I2C Digital Temperature sensor form Microchip. TC74 is a serially accessible digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word. In this tutorial we are going to learn how to use MPLAB Code Configurator to read temperature from the TC74 temperature sensor and display it on an LCD
