You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a ...

Editor's Note: Embedded Linux has consistently ranked among the top operating systems used in embedded system design. With the rapid growth in interest in the Internet of Things (IoT), the ability of ...

In my last column [LJ, December 2003], we discussed how I2C bus drivers and I2C algorithm drivers work. We also described how to make a tiny dummy I2C bus driver. This month, we discuss how an I2C ...

The I2C bus is a set of hardware and software rules that allows communication between multiple devices over a shared, two-wire interface. In operation the bus uses one line (SDA) for data and the ...

Inter integrated circuits (I2C) is a multi-master, low-bandwidth, short distance, serial communication protocol. Because of its simplicity and flexibility, I2C and its derivatives are widely employed ...

We used the Bus Pirate universal serial interface tool to work with the DAC, but the same basic principals apply to any custom implementation. The connections between the Bus pirate and the LTC2631A ...

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a ...
