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 ...

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 ...

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 ...

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.

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, ...

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 ...

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 ...
