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 ...

I2C makes connecting multiple sensors to a Raspberry Pi straightforward by sharing just two pins for communication. With proper setup, scanning, and coding, you can integrate dozens of devices on a ...

The PCA9635 is an I²C-bus controlled 16-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 ...

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 ...
