WebbWhen the master has finished writing all data to the slave, it sends a stop sequence which completes the transaction. So to write to a slave device: 1. Send a start sequence. 2. Send the I2C address of the slave with the R/W bit low (even address) 3. Send the internal register number you want to write to. 4. Webb6 maj 2024 · LCD 4004 ( 40x4 ) I2C working.

WebbYou can add up to seven additional chips onto the same I2C bus giving you a total of 32 analogue ADC inputs, and 8 DAC analogue outputs. The PCF8591 also has a separate ground input. With this input you can keep analogue and digital grounds separate (and only connect them at the power supply ground).

WebbMost datasheets only give the I2C address for their device either in binary notation or as bits on timing diagrams (with notes for configurable address bits), which are both unambiguous as they either display seven or eight bits so you can tell if the R / W ¯ bit is included.
