MIPI I3C Standardized Sensor Interface – Advantages and Disadvantages
CNX have a simple table breakdown of the advantages and disadvantages – and other specifications – between SPI, I2C, and the Sensor Work Group’s I3C standardized sensor interface, announced in a whitepaper (link at bottom) late last year and made official earlier this month. You need to be a MIPI member to gain access to the full specification but the at-a-glance is useful for anticipating forthcoming sensor-based development.
I2C (Inter-Integrated Circuit) is one of the most commonly used serial bus for interfacing sensors and other chips, and use two signals (Clock and Data) to control up to 128 chips thanks to its 7-bi address scheme. After announcing it was working of a new I3C standard in 2014, the MIPI Alliance has now formally introduced the MIPI I3C (Improved Inter Integrated Circuit) Standardized Sensor Interface, a backward compatible update to I2C with low power consumption, and higher bitrate allowing it to be used for applications typically relying on SPI too.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
