This is a simple program to read a byte from an i2c client under Linux. It is provided as example code; if you want a real program use i2cget from the i2c-tools package. It assumes the i2c client does ...

For testing I've used the Arduino nano to emulate two devices, one I2C photoresistor sensor and one SPI PWM LED. These devices, for example, could be two different attiny85; but as the atmega368p is ...

In the June and August 2003 issues of Linux Journal, my column covered the Linux kernel driver model, and the I2C subsystem was used as an example. This month, we discuss what the I2C subsystem does ...

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 (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
