I’d love to see more adoption of… I2C!
Bazillions of motherboards and SBCs support I2C and many have the ability to use it via GPIO pins or even have connectors just for I2C devices (e.g. QWIIC). Yet there’s very little in the way of things you can buy and plug in. It feels like such a waste!
There’s all sorts of neat and useful things we could plug in and make use of if only there were software to use it. For example, cheap color sensors, nifty gesture sensors, time-of-flight sensors, light sensors, and more.
There’s
lmsensorswhich knows I2C and can magically understand zillions of temperature sensors and PWM things (e.g. fan control). We need something like that for all those cool devices and chips that speak I2C.If you have an unused VGA port, you can use the DDC pins for I2C. Be sure to add ESD protection if you do this. An I2C isolator would be even better.
I2C is really not meant to be used over cables. It has a very limited common mode input voltage range and it can’t handle much capacitance on the bus.
