WebMar 22, 2024 · When devices are addressed in an I2C/SMB bus, the 7 address bits are sent out first, followed by a single Read (0)/Write (1) bit. So if you take the 1st 7 bits as 0x50 and shift them left 1 bit to add on a Read (0) bit, you get an 8-bit result of 0xA0. If you instead use a Write (1) bit then you'd get 0xA1 instead. dysmech group of companies
