Table 67. I2Cs_PutBuffer
Note: The above function is only for I2C_ITDRV_WITHOUTBUF_TX mode.
Caution:
– Any data transmitted before using this function will be neglected through dummy byte
Overflow condition: The overflow bytes are neglected through dummy bytes.

* The maximum size of the buffer is under user control.
‘I2C interrupt driven’
I2Cs_PutBuffer
Void I2Cs_PutBuffer(unsigned char *PtrToBuffer, un-
signed char MaxSize)
Starts transmission of data from the user defined area by
initializing the transmission buffer for
I2C_ITDRV_WITHOUTBUF_TX mode
*PtrToBuffer
Start address of the user buffer
MaxSize
Size of the buffer
None
1. You must define I2C_ITDRV_WITHOUTBUF_TX mode
in ST7lib_config.h
2. I2C communication mode must be detected through the
I2Cs_GetCommMode
None
I2Cs_IsTransmitCompleted should be called to know the
current status of transmission
I2Cs_PutBuffer (I2C Polling mode)
I2Cs_PutByte
Void I2Cs_PutByte (unsigned char Tx_Byte)
Transmits single byte on the I2C bus
Tx_Byte
The byte to be transmit on the I2C bus
None
1) I2Cs_GetCommMode must have been called before
transmitting first byte to check whether the
I2Cs_TX_MODE is selected or not
2) Transmission of previous data has been taken success-
fully, which should be checked through the
I2Cs_IsTransmitCompleted
None
None
