As the name … WebUnderstanding the I2C Bus 1.1.2 Open-Drain Releasing Bus When the slave or master wishes to transmit a logic high, it may only release the bus by turning off the pull-down FET. This leaves the bus floating, and the pull-up resistor will pull the voltage up to the voltage rail, which will be interpreted as a high.

Before we get into any details, here are the key characteristics of I 2 C: Only two signals (clock and data) are used, regardless of how many devices are on the bus. Both signals are pulled up to a positive power supply voltage through appropriately sized resistors. Every device interfaces to the clock and data ... Web2 dagen geleden · I2C is a transaction-based bus. Each transaction ahs a start and stop condition and an arbitrary number of byte transfers in-between. If you're the only I2C master ont eh bus, the oly one who can start a transaction is you. The busy bit only indicates whether a transaction start has been detected and no transaction end has happened yet.
