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
Issues following sequence:
Lock
