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.. -

Recreating Lab Measurements As RTL Stimulus
Torgeir Leithe Recreating lab measurements as RTL stimulus Master’s thesis in Electronic Systems Design Supervisor: Kjetil Svarstad June 2019 Master’s thesis Master’s NTNU Engineering Department of Electronic Systems Department of Electronic Faculty of Information Technology and Electrical Technology of Information Faculty Norwegian University of Science and Technology of Science University Norwegian Torgeir Leithe Recreating lab measurements as RTL stimulus Master’s thesis in Electronic Systems Design Supervisor: Kjetil Svarstad June 2019 Norwegian University of Science and Technology Faculty of Information Technology and Electrical Engineering Department of Electronic Systems Abstract Most of modern IC design verification is conducted as RTL simulations. However, the final verification steps must be done on physical silicon. If unexpected behavior is found at this stage, understanding the problem can be a challenge. The understanding of the problem is limited by all the internal signals and states in the DUT being hidden. Only the external signals can be probed. By recording all the stimulus applied to the IC, the conditions triggering the issue can be recreated in the RTL simulations. This enables a greater understanding of the inner workings of the IC at the time the issue occurs. This thesis investigates ways of assisting the designer in this process. By taking advantage of most stimulus applied to the DUT being part of a communication protocol, focus can be moved from the signals them self, to the information transmitted by the signals. Decoding the signals to a protocol level allows for reuse of existing testbenches. The information being presented at a protocol level also makes analysis of the problem simpler for the designer. -
Mobile Data-Logger for Ultra-Low Current and Power Measurements
Institut für Technische Informatik und Kommunikationsnetze Department of Information Technology and Electrical Engineering Spring Semester 2016 RocketLogger: Mobile Data-Logger for Ultra-Low Current and Power Measurements Semester Thesis, SA-2016-40 Matthias Leubin, Stefan Lippuner [email protected], [email protected] June 2016 Supervisors: Lukas Sigrist, [email protected] Andres Gomez, [email protected] Roman Lim, [email protected] Professor: Prof. Dr. L. Thiele, [email protected] Abstract With the appearance of wearable devices and the Internet of Things (IoT), energy harvesting nodes are becoming more and more important. These small standalone sensors and actuators, which harvest very lim- ited amounts of energy from their environment, are driving researchers into the development of ultra-low power devices. To evaluate new de- signs, very accurate and fast measurement systems are required, which are able to capture the rapidly changing currents. On the other hand, the necessity of real-world experiments creates a demand for compact and portable equipment. In this thesis we present the RocketLogger, a measurement device, which combines both properties, mobility and accuracy. It is able to measure powers in the range of 100 pW up to 2.5 W within the same measure- ment, while not being bigger than a human hand. The custom analog front-end allows the logging of power on several channels with sampling rates of up to 64 kSPS. In addition, it guarantees high precision over a dynamic range of 165 dB and has a seamless auto-ranging capability. The software handles the acquisition and logging of up to 13 Mbit/s of sensor data. -

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. -
