I2C_ReadBurst
The function I2C_ReadBurst reads a number of iNumberBytes from a i2c-device specified with uSlaveAddress.
int I2C_ReadBurst( UCHAR uSlaveAddress, UCHAR* pBuffer, UCHAR ucOffset, WORD iNumberBytes ); int i2c_BurstRead( UCHAR uSlaveAddress, UCHAR* pBuffer, UCHAR ucOffset, WORD iNumberBytes );
Parameters
uSlaveAddress
Slave-Address of the i2c-device.
pBuffer
Buffer to receive data.
ucOffset
Offset at where to begin with data-read. This is also the offset, where data will be written to pBuffer.
iNumberBytes
Number of bytes to read.
Return Values
Returns 0 if succesful.
Remarks

- Lock
- Start
- SlaveAddress with write-bit
- ucOffset
- SlaveAddress with read-bit
- Read specified number of bytes
- Stop
- Unlock
This function calls I2C_Lock and I2C_Unlock to prevent multiple accesses to the i2c-bus. Don't lock access to i2c-bus prior to using this function!!
