This article is the primary inside a series describing the more 'subtle' areas of the I2C Protocol, initially developed by Philips.

Because you're examining this series, I'm assuming you already know what the I2C bus is, and you're looking to prevent some ache when you'll want to utilize it within a challenge. If so, you've come to the appropriate spot. If not, I'll be incorporating some introductory I2C facts shortly at my Web-site.

Just so we're distinct, this series will not likely contain protection of your Significant-speed manner, as That is substantially distinct from the look and actions of the traditional two-wire shared-bus implementation, and is usually not that normally utilized. There is certainly a great deal of excellent reference content out there on the net that addresses this manner.

Here's A fast listing of what will be coated in the rest of the series:

Now, on to The nice things!

For this short article, We're going to target The three different types of implementations you'll find in layouts nowadays: full components, components/application combine, and complete software package (or 'little bit-bang' because it is usually referred to as).

Many microcontrollers currently, even some very low-conclude units, include a completely-components I2C peripheral. Atmel refers to theirs as TWI, Microchip calls theirs I2C; other distributors use identical naming. When using a entirely-components solution, it is really tricky to produce any type of bus mistake Except if you misunderstand how the peripheral functions or what an accurate I2C bus sequence should really appear to be. Normally, although, this technique needs the the very least in-depth understanding of the protocol alone.

The USI peripheral located in some Atmel equipment is often a minimum-hardware style that depends on software package interaction to really make it a whole implementation. This versatile peripheral can actually be employed for I2C, SPI and UART configurations, and is also suitable for very low-conclusion products wherever adding all a few peripherals could well be Price tag-prohibitive. Even though it necessitates additional coding than the usual TWI or whole-components I2C peripheral, it is in certain methods much more versatile. This technique requres a more in-depth comprehension of the protocol, as you are to blame for moving from one particular condition to another, and it is achievable to go in the incorrect course.

Lastly, implementing a one hundred% program technique requires a complete comprehension of the I2C protocol. Pretty much every microcontroller seller gives application notes and code examples for creating an I2C Master unit utilizing a pure-program Alternative. Compared with a UART, I2C is a clocked (in lieu of timed) protocol, so interruptions from the execution of the protocol are tolerated very well, allowing for interrupts being serviced without having problem for getting rid of information. The maximum speed on the program-based solution is eventually based on the CPU clock velocity, and typically a Learn implementation can certainly reach the 400KHz price.

A application-primarily based implementation of the Slave system is way tougher. Devoid of components guidance, the software should observe both equally the SDA plus the SCL strains at the same time to be able to detect clock edges and know positively the condition of the SDA line previous to the rise or fall of SCL. Detection of the Begin or Prevent problem will often require the use of interrupts, in any other case the computer software would need to get a hundred% consumed with checking SCL and SDA. Program-dependent Slave implementations are usually CPU-certain, necessitating numerous MIPS to realize even 100KHz Procedure. Thus, accurate software program-only Slave implementations may well not even exist for many microcontroller families, and Other people may not be able to achieving full 100KHz bus speed.

Using this components and software package Basis obtaining been laid, We are going to dive further in to the protocol alone inside our up coming posting. Many thanks for reading through!
