I don’t know exacterly why. Initial and final energy stored in a capacitor So addressing upto 0x01FF is possible.

Even though the master floats the clock high, it can still be held low by the slave util it is ready for the next clock.

Read-Only Author erik malund Posted Aug The clock on the I2C bus is “negotiated”. By continuing to use our site, you consent to our cookies. If the character which i get from pc is ‘w’ or ‘W’ then i do get data from PC and write to AT24c04 until i get the 0x0D.
