The I2C waveform is one of the most common, and today we will directly discuss the diagram.Start Signal:Figure 1Acknowledge Signal:Figure 2Stop Signal:Figure 3Figure 4Acknowledgment:SACK: acknowledged by slave; the slave device acknowledges the signal, low level indicates received;MACK: acknowledged by master; the master device acknowledges the signal, low level indicates received;NACK: Not acknowledged; the device is … Read more
Why do we need pull-up resistors in I2C? Because it uses open-drain output. Why is it open-drain output? The I2C protocol supports multiple master devices and multiple slave devices on a single bus. If push-pull output is used instead of open-drain output, it could lead to short circuits between master devices. Therefore, the bus generally … Read more
In modern society, Wi-Fi has become an indispensable part of our lives. However, concerns about the potential negative health impacts of Wi-Fi radiation have also arisen. In fact, most of these concerns are unnecessary. The radiation generated by Wi-Fi and base stations does not significantly affect human health. Radiation is ubiquitous in daily life, but … Read more
