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.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

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.
