2024年9月5日 · There’s a solution – it’s called clock stretching, and it’s basically an I2C device holding SCL low after receiving a byte, extending ACK state for a long time, until it can actually return...

2022年3月30日 · Let’s start by setting up a simple hardware hacking experiment and capture I2C traffic directly from the wire. For experimenting and learning, we should use a controlled and …

2024年8月7日 · A small I2C chip can help you get more GPIOs for your MCU or CPU, or a multi-channel motor driver, or a thermal camera, or a heap of flash memory; if you’re adding some sort of cool chip onto ...

Use Trickest to easily build and automate workflows powered by the world's most advanced community tools. Reading time: 5 minutes. To test a Bus Pirate is working, connect +5V with VPU and 3.3V with ADC and access the bus pirate (Using Tera Term for example) and use the command ~: MODE and VREG LEDs should be on! Found 0 errors.

2025年3月12日 · One of the biggest additions from the last week or so of development has been the I2C sniffer — a valuable tool for troubleshooting or reverse engineering devices using the popular communications...

2022年4月7日 · 本文详细介绍了I2C协议的工作原理，包括时钟设置、数据传输、响应机制以及时钟同步。 主设备通过控制SCL和SDA线进行数据传输，从设备在接收到数据后需要给出ACK响应。

2023年10月9日 · We will use SPI to extract data from EEPROM and other flash memory chips, which often contain firmware and other important data such as API keys, user passwords, and service URLs. We’ll also look at I2C, create our own architecture to communicate over this serial bus, and then learn how to sniff and control devices to make them do certain things.

2022年4月8日 · András Tevesz demonstrates and explains some of the fundamentals of hardware hacking recon and internals of wire protocols. I2C or (eye-squared-C) is a synchronous, multi-master, multi-slave, packet-switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors.

Explore the fundamentals of the I2C protocol, uncover security issues, and discover the potential types of attacks. From identifying I2C pins on IoT products to utilizing cutting-edge EXPLIoT tools for sniffing and hacking I2C chips, this course equips you with the skills to navigate the vulnerabilities within this essential communication protocol.

Originally written for a Dell J1KND battery that uses a BQ8050 fuel gauge IC. Arduino folder contains the source code for an Uno/Mega which acts as an interface between the battery and an external computer. The I2C pins are connected to the smart battery's SDA/SCL pins with pullup resistors (4.7kOhm to 5V).
