3.1 I2CHandle Description

Table 3-3 provides the details of I2CHandle structure defined in the example code.

Table 3-3 Details of I2CHandle
Structure Members Description
base Base address of I2C module used
SlaveAddr Slave address of EEPROM
pControlAddr Pointer to variable which stores EEPROM address
NumOfAddrBytes Number of address byte required by EEPROM
pTX_MsgBuffer Pointer to TX message buffer
pRX_MsgBuffer Pointer to RX message buffer
NumOfDataBytes Number of data bytes in a I2C transaction
currentHandlePtr Pointer to I2CHandle object
numofSixteenByte Number of 16 bytes in data packet

Note: FIFO depth in 16. so, we calculate number of 16 bytes.

remainingbytes Number of bytes which are less than 16 bytes
WriteCycleTime_in_us Write cycle time (in us) defined based on EEPROM
