I2C @ Dorkbot PDX 0X08
Sailing the I2Cs with the Bus Pirate ShareBrained Technology Jared Boone DorkbotPDX 0x08 - January 30, 2012 Tuesday, February 26, 13 Hi, I'm Jared Boone. I'm going to speak about the I2C bus, and a cool gadget, called the Bus Pirate, that makes working with the I2C bus a lot easier. “I2C”? • “Inter-Integrated Circuit” bus. • Truth in naming: provides a way for integrated circuits (chips) to communicate. • Very simple. So simple it costs virtually nothing to implement inside a chip. • PCI, USB, even PC-style serial ports are more complicated and expensive to put in a chip. And they’re all overkill for chip-chip communication. Tuesday, February 26, 13 So what is I2C? It’s a communication bus designed specifically for chips to communicate with each other, very inexpensively. The best way to make something inexpensive is to make it simple. And I2C is definitely simple. It’s *almost* the simplest form of digital communication conceivable. Way simpler than PCI or PCI Express. Way simpler than USB. Simpler, even, than a PC serial port. What Speaks I2C? • Many integrated circuits -- sensors, memories, chips that need to be configured/controlled externally. • Most microcontrollers speak I2C, too. The Arduino (AVR8), ARMs, MSP430s, PICs, you name it! Tuesday, February 26, 13 OK, so it’s simple. But what is it good for? A lot of fun and interesting chips implement I2C, as do virtually all the microcontroller chips available. Here are some examples: Sensors SparkFun.com SparkFun.com SparkFun.com Tuesday, February 26, 13 Analog Devices ADXL345 three-axis accelerometer Honeywell HMC5843 three-axis magnetometer (compass) Invensense ITG-3200 three-axis gyroscope Many others available -- temperature, humidity, pressure, light/color.. -

Schwartz Department of Electrical & Computer Engineering Revision 0 Dave Ojika, TA Page 1/10 Digilent Analog Discovery (DAD) Tutorial 6-Aug-15 INTRODUCTION The Diligent Analog Discovery (DAD) allows you to design and test both analog and digital circuits. It can produce, measure and record many types of signals. It allows circuit designers to both simulate circuits and observe their behaviors for testing, debugging and other kinds of signal analysis. Follow this link http://tinyurl.com/DAD-vids for short videos, and http://tinyurl.com/DAD-page for product page. Figure 1 shows the normal setup for a DAD. Figure 2 shows the functions of each of your DAD’s pins. Figure 2: DAD pin configuration DAD -- ANALOG FUNCTIONS This section demonstrates some of the basic features of the DAD using Arbitrary Waveform Generator (AWG) and Scope instruments in the WaveForms software. AWG and Scope both make up the analog functions of the DAD – the former serves as analog output, while the latter serves as analog input. A breadboard board, augmented with a few other parts, can provide Figure 1: Connection of the DAD to a circuit and a USB port on a computer you a means to build and verify the proper operation of digital circuits. Some of the useful Your DAD has the following basic features. devices are described below. • 2-Channel Oscilloscope Arbitrary Waveform Generator (AWG) • 2-Channel Waveform Generator The AWG has two channels that can • 16-Channel Logic Analyzer independently generate both standard • 16-Channel Digital Pattern Generator waveforms (sine, triangular, sawtooth, etc.), as • ±5VDC Power Supplies well as arbitrary waveforms that are defined • Spectrum Analyzer using standard tools such as Excel. -

Introduction
Introduction The Bus Pirate is an electronics prototyping dream. It’s packed with many of the tools needed when getting a project up and running. The Bus Pirate can perform a variety of test equipment functions such as measuring voltage and frequency as well as generating PWM signals. Most of the functionality of the Bus Pirate revolves around serial protocols. The Bus Pirate can communicate on 1-wire, 2-wire, 3-wire, UART, I2C, SPI, and HD44780 LCD protocols. It also has a bitbang mode for other or custom options. This guide is intended to be a quick overview and cover a few things not explicitly covered in the Bus Pirate documentation provided by Dangerous Prototypes. Suggested Reading The following concepts will be mentioned in this guide. If you are unfamiliar with any of them, check out the corresponding tutorial. Serial Communication I2C Communication Serial Peripherial Interface (SPI) Pulse-width Modulation (PWM) Serial Terminal Basics Board Overview Bus Pirate Ports The Bus Pirate has 3 ports. This first is the ICSP port for directly programming the PIC microcontroller at the heart of this product. Since there is a bootloader and a reflashing utility, you shouldn’t ever have to use this port. The second port is a mini-B USB jack. Connect this to a computer with a standard A to mini-B cable. This provides the power to the board and allows you to communicate with Bus Pirate. The third port is the most interesting. It’s a shrouded 0.1" pitch 2x5 pin header. We sell a handy cable to connect the Bus Pirate to the system you are developing, debugging, or reverse engineering. -
