  Troubleshooting I2C Bus Protocol
  PDF, 184 Кб, Файл опубликован: 19 окт 2009
  When using the I2Cв„ў bus protocol, the designer must ensure that the hardware complies with the I2C standard. This application report describes the I2C protocol and provides guidelines on debugging a missing acknowledgment, selecting the pullup resistors, or meeting the maximum capacitance load of an I2C bus. A conflict occurs if devices sharing the I2C bus have the same slave address. This

  Choosing the Correct I2C Device for New Designs
  PDF, 87 Кб, Файл опубликован: 7 сен 2016
  The I2C bus is a very popular and powerful bus used for communication between a single (or multiple)master and a single (or multiple) slave device. In many applications there is a potential need for moreslave devices on the bus, isolation between similar addressed slaves, or a need for more I/Os. Theseneeds can be solved with an I2C buffer, switch, and I/O expander.The application note h
