Webb5 juni 2024 · I2C Starting with v0.2, the smbus2 library also has support for combined read and write transactions. i2c_rdwr is not really a SMBus feature but comes in handy when the master needs to: read or write bulks of data larger than SMBus' 32 bytes limit. write some data and then read from the slave with a repeated start and no stop bit between. WebbThe I2C protocol is used in a huge range of chips - just a few examples from this site include the DS1307 (RTC), SSD1306 (OLED Display), MCP23017 (Serial expander). …
