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 ...

In the last Driving Me Nuts column [see LJ, June 2003], we introduced the kernel driver model framework with an explanation of how the generic bus and driver and device code works. The i2c core was ...

Communicating with microcontrollers and other embedded systems requires a communications standard. SPI is a great one, and is commonly used, but it’s not the only one available. There’s also I2C which ...

Hi all. I'm doing a robotics project for my last month of high school with a friend, and we're looking at ways to control the I/O and motor electronics. We plan to use a Palm III for the brain, ...

The PCA9633 is an I²C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency ...

This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

STMicroelectronics has introduced a stereo headphone and loudspeaker driver chip, with a I2C bus control interface. The TS4956, in a lead-free 2.5×2.4mm flip-chip package, can drive up to 38mW per ...

A fundamental skill that embedded software developers need to master is understanding how to write drivers. Within an embedded system, there a typically two types of drivers: microcontroller ...

The PCA9634 is an I²C-bus controlled 8-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency ...
