Function Descriptions
Table 56. I2C_GetBuffer
Notes:
– The above function is only for I2C Interrupt driven mode.
– ACK bit is managed automatically inside this routine.
– STOP bit is set automatically inside this routine, before the last byte is read. So there is no
Caution:
– Take care not to access the string until reception completion.
– Any data received before calling this function is ignored.
– The data reception will stop if any error occurs during reception.
– In String reception, the NULL character must be taken into account.

need to call I2C_Generate_Stop after this.
I2C_GetBuffer
Void I2C_GetBuffer (unsigned char *PtrToBuffer, un-
signed char NbOfBytes)
Starts reception of data and stores it in user defined area
for I2C Interrupt driven mode.
*PtrToBuffer
Start address of the user buffer.
NbOfBytes
Number of bytes to be received.
None
1. I2C_Load_Address must have been called (If I2C is
configured in master receiver mode).
2. You must define I2C Interrupt driven mode in
ST7lib_config.h.
3. I2C_IsReceptionCompleted must have been called to
ensure that there are no pending requests.
4. You must enable interrupts for this mode.
5. In I2C Interrupt driven mode, I2C_IT_Function must
have been called in the Interrupt service routine.
None
I2C_IsReceptionCompleted must be called after this func-
tion to get the status of reception.
