I2C protocol - no ACK from slave Microchip

WebbI2C is a two wire serial protocol that allows an I2C Master exchange data with an I2C Slave. The I2C protocol support upto 127 devices per bus. The I2C interface can be used for writing data words out of the I2C port, returning the data recieved back from I2C slave. The I2C clock frequency can be configured. WebbAt least one start and stop bit is a part of each frame of data, meaning that 10 bits of transmission time are required for each 8 bits of data sent, which eats into the data rate. …
