A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, ...

NXP Semiconductors’ family of level shifting bus buffers are detailed in this application note that discusses device operation, maximum cable length and frequency ...

NXP would like to introduce the industry’s first no-offset I2C bus buffer to isolate capacitance and interface with all other bus devices. NXP Semiconductors introduced the PCA9525 and PCA9605 — the ...

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 ...

The LTC4303 and LTC4304 two-wire bus buffers from Linear Technology solve the common problem of a stuck I2C/SMBus bus by isolating all of the bus connections on the upstream side, while restoring the ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

Maxim has introduced a chip to interface devices equipped with I2C or SPI bus connections to its ‘1-wire’ bus. Called DS28E18, it is intended to knock cost out of networks that connecting I2C and SPI ...

The EEPROM, ADC and RTC will require an interface for communication between them. Due to that I2C bus is used as an interface between EPROM, ADC and RTC. It is used to minimize system-level ...

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 ...
