Polling mode.
* This is applicable only in multimaster I2C.
I2C_PutBuffer
I2C_TxErrCode_t I2C_PutBuffer (const unsigned char
*PtrToBuffer, unsigned char NbOfBytes)
Transmits data string in I2C Polling mode from the user
defined area. The data transmission will stop if any error
occurs during transmission. The transmission status will
be returned.
*PtrToBuffer
Start address of the user buffer.
NbOfBytes
Number of data bytes to be transmitted.
I2C_TX_AF
If Acknowledge failure has occurred.
I2C_TX_ARLO*
If Arbitration lost is detected.
I2C_TX_BERR*
If misplaced start or stop condition detected.
I2C_DATA_TX_OK
If sub-address is successfully transmitted or there is no er-
ror in data transmission.
1. I2C_Load_Address must have been called (If I2C is
configured in the master transmitter mode).
2. You must define I2C Polling mode in ST7lib_config.h.
