Recently I came across Total Phase, a company I hadn't heard of. The company sells a line of small modules that monitor, analyze, and control I2C and SPI communications in embedded systems. The ...

Supporting I 2 C data rates to 5 Mbits/s, the CAS-1000-I2C can monitor and log real-time bus traffic, generate traffic to exercise the bus and its components, program in-system EEPROMs, validate ...

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 ...

I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...
