This library provides ESP32 Slave functionality as a workaround for the lack of support on Arduino core and on ESP-IDF. There are caveats though, keep reading. Right now, the I2C Slave functionality ...

BTW, this is still not working in Espressif IDE examples or Arduino Wire examples. It always sends garbage back to I2C Master because TX FIFO Empty & ACK/NACK not working. Anyhow, from time to time ...

Before we get started into programming I2C using two Arduinos. We need to learn about the Wire library used in Arduino IDE.. The library <Wire.h> is included in the program to use the following ...

Those include the factory test tool, RS485 Master/Slave samples, an SPI sketch, and as a “Wire” program showing how to use I2C. Since an ESP32-S3 board for vending machines is a rather niche product, ...

This application note describes a TWI master implementation, in the form of a full-featured driver and contains an example of usage for this driver. The driver handles transmission based on the both ...
