MIPI I3C (also known as SenseWire) is a specification to enable communication between computer chips by defining the electrical connection between the chips and signaling patterns to be used. The standard defines the electrical connection between the chips to be a two wire, shared (), serial data bus, one wire (SCL) being used as a clock to define the sampling times, the other wire (SDA) being

Once SCL is high, the master waits a minimum time (4 μs for standard-speed I2C) Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors.

I would like to know which pins should be used for SDA / SCL on the chip. BT Nordic pinmuxing for I2C SDA and SCL pins is done with sda-pin and scl-pin DTS properties. Move these to a more idiomatic sda-gpios and scl-gpios style instead. A prototypical example for how the devicetree should be updated is: &i2c1 { compatible = "nordic,nrf-twim"; status = "okay"; - sda-pin = <41>; - scl-pin = <11>; + sda-gpios = <&gpio1 9 0>; + scl-gpios = <&gpio0 11 0>; }; The old 2021-04-06 :param scl: PIN number for the SCL (serial clock) line. :param sda: PIN number for the SDA (serial data) line.

Yes, you must include the Wire library to use sda/scl. I never heard of an Uno with D16/17 pins. Uno clones normally have the same pins as a genuine Uno, otherwise they can't sell themselves as clones. Paul We can conveniently tie both the SCL and SDA pins together in order to achieve what we want.

A circuit schematic is shown and discussed, then BASH commands are used to connect and communicate with the chip. I followed this tutorial to get lux measurement from GY-30 BH1750 with Arduino.

SDA is the Serial Data line. The master and slave devices send and receive data over this wire. SCL is the Serial Clock line. It carries the clock signal generated by the master.

Good to know. I wish the installation instructions included this bit of information. I originally had the SCL and SDA pins connected to my Pi 3, which caused intermittent conflicts with the HiFiBerry.
