OLED is an Organic Light Emitting Diodes. OLED is a flat emitting technology based screen. OLEDs are emissive display that does not require a backlight, so are thinner and more efficient and LCD display which require a white backlight. OLED display are not just thin and efficient, they provide the best image quality ever as […]

The DS1307 serial real time clock is a low power, full binary-coded decimal (BCD) clock/calendar plus 56bytes of NV SRAM. Address and data are transmitted serially via 2-wire, bi-directional bus. The clock/calendar provides seconds, minutes, hour, day, date, month and year information. The end date at the month date is automatically adjusted for months with
EEPROM stands for electricity erasable programmable read only memory and it is a type of non-volatile memory used in different application. It is read only memory whose data can be erase and re-programmed by higher than normal current of electricity. Many microcontrollers have in build EEPROM. In this article we use AT24C512 serial EEPROM. It
We already learn LCD interfacing in GPIO part. LCD Display requires lots of digital I/O pin and the circuit requires more space. In market I2C LCD display are available and the interfacing is not so difficult. You just need the hardware and the I2C IC which is connected with that LCD. Usually in maximum I2C
In SPI communication we use MCP23S17 with SPI transmission. In this article we use same IC MCP23017 with I2C transmission. Let’s look at the connection diagram. The I2C protocol for MCP23017 is as follow- Here the first 4 bits is the logical address and last 3 bits A2: A0 are the physical address. Since we
I2C( read as I square C) bus first introduced by Philips. Because of its simplicity and flexibility the I2C bus has become one of the most microcontroller bus system used for interfacing various IC. The I2C bus use only 2 bidirectional data lines for communicating with the microcontroller and the I2C protocol specification can support
