The master device communicates with particular slave device by an address. Every slave device must consist of own address to represent on it. Device Addressing: I2C bus protocol allows many slave devices at a time. The standard quartz crystal frequency is 22.768KHzs. OSC0 and OSC1: These are crystal oscillator pins which are used to provide the clock signals to the RTC device. Clock Out: It is an optional square wave output pin. It is used to transmit and receive the data on serial interface. Bagaimana memodifikasi program Bascom supaya bisa diterapkan pada produk yg saya punya? All in One - 32 function and sub, RTC ds1307 1307 in Mikroc avr:). SDL: It is a serial input and output pin. SCL: SCL is a serial clock pin and it is used to synchronize data on serial interface. VBT: VBT is a battery power supply pin.īattery power source must be held between 2V to 3.5V. This device operated with 1.8V to 5.5V range. VCC and GND: VCC and GND are power supply and ground pins respectively. We can control eight devices with RTC interfacing with by A0, A1, A2 bits using I2C protocol.

RTC DB1307 Configuration: RTC Internal Blocks and Pin Diagram A0, A1, A2: are address pins of RTC DB1307 chip, which can be used to communicate with the master device. A battery backup will be provided in case of failure of main power supply by connecting a battery to RTC device. Step2: Internal Register and Address of the RTC Device RTC stands for real time clock which provides years, months, weeks, days, hours, minutes and seconds based on crystal frequency. Then we can select features of RTC device depending on requirement of application such as battery life, suitable package and clock frequency. Four-wire Serial interface (SPI BUS) First, we need to select type of RTC device by category based on requirement like I2C Bus RTC or SPI Bus RTC or other, which suitsfor interfacingwith respective microcontroller.Step1: Select RTC Device The various kinds of RTC chips are available in the real time embedded world, which are classified based on various criteria such as package type, supply voltage and pin configuration etc. So let us look on simple RTC interfacing with and programming procedure involving in it.

RTC Interfacing with 8051 Microcontroller RTC Programming and Interfacing RTC interfacing with 8051 microcontroller is similar to all other kinds of “Real Time Clocks” interfaced to it.
