Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

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.

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. More for You. Who Won and Lost in Trump’s Tax Bill.

[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature l… ...

The Arduino UNO R4, featuring the Renesas RA4M1 (Arm Cortex-M4) running at 48MHz, boasts a 3x performance increase over the UNO R3. Additionally, SRAM has been upgraded from 2kB to 32kB, and flash ...

Arduino intends to provide a public list of such libraries, with links to alternatives. To aid library developers in porting low-level code to the Renesas architecture, there is and early-adopter ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
