Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

I wrote some I2C sniffer code for a silabs C8051F340 MCU one time. On that MCU, it has specialized I2C hardware, so you only have to peek/poke certain registers to make the I2C bus do what you want.

Once hooked up to your microcontroller, be it a Raspberry Pi or any other compatible device in this case an Arduino microcontroller, it delivers 64 distinct infrared temperature data points using I2C.

This project is devised for LED dimming using NXP Semiconductors’ PCA9532 16-Bit I2C-Bus LED dimmer. A lot of solid-state lighting applications require control over the emitted intensity of light for ...

[Pawel] wired up a tremendously simple circuit, downloaded some I2C slave-mode code, and added an LED for good measure. It’s all up on GitHub if you’re interested. Bright by Day, Dark by Night!

I2C sets 16 channel LED flasher An open-drain port expander for microcontrollers, the Catalyst Semiconductor CAT9552, is aimed at switching and flashing LEDs for advertising and industrial control.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Marvell has announced an ac-dc LED driver chip which is both dimmable over an I2C serial bus and by phase-cut wall dimmer. Called 88EM8189, it can be used in either non-isolated buck-boost or isolated ...

Date Announced: 24 Jun 2008 Highly Integrated Chip Combines Seven LED/Flash Drivers with 3 LDOs Santa Clara, CA – June 24, 2008 – Advanced Analogic Technologies Inc. (AnalogicTech) (Nasdaq: AATI), a ...
