Table 51. I2C_PutString
Note: The above function is only for I2C Interrupt driven mode.
Caution:
– Take care not to access the string until transmission is complete.
– The data transmission will stop if any error occurs during transmission.

I2C_PutString
Void I2C_PutString (const unsigned char *PtrToString)
Starts transmission of a data string in I2C interrupt driven
mode from the user defined area.
*PtrToString
Start address of the user string.
None
1. I2C_Load_Address must have been called (If I2C is
configured in master transmitter mode).
2. You must define I2C interrupt driven mode in
ST7lib_config.h.
3. I2C_IsTransmitCompleted must have been called to en-
sure that there are no pending requests.
4. You must enable interrupt for this mode.
5. I2C_IT_Function must have been called in the Interrupt
service routine.
None
I2C_IsTransmitCompleted can be called after this function
to get the transmission status.
