The I2C (Inter-Integrated Circuit) bus is a two-wire bidirectional bus used for low speed, short-distance communication between integrated circuits.

This application note provides an overview of the I2C bus (focusing on its physical layer), discusses the challenges in isolating I2C interfaces, and describes iCoupler solutions for isolating I2C interfaces.

The DS1307 serial real-time clock (RTC) is a lowpower, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM.

I2C or SPI communication this is the question!
Serial Peripheral Interface Bus (SPI) was established by Motorola and Inter Integrated Circuit (I2C) was invented by Philips. So the main protocols to consider are: SPI protocol and I2C protocol.

The UNI/O microcontroller technology has been recently released by Microchip. It consists of a proprietary single I/O bus protocol, where the bus combines the clock and data lines into a single bit stream using the Manchester Encoding technique. Since Microchip already is one of the leading microcontroller and memory devices it is likely that the near future will see an increased use of this pin saving technology.

I am continuing with the intention to realize a BLOG truly complete on electronics, that would avoid waste of time searching on the net, I understand that is a HEAVY job!

The time that I have is not so long and in order to make a library with project guides (like: WHAT DO YOU WANT TO DESIGN(PLAN) TODAY?) it takes a while.
