Table 15. SCIx_PutBuffer
Note: This function is for Polling or Interrupt driven mode.
Caution:
– The application can lose control if the SCI is disabled while using this function in polling
– Take care not to access the user buffer until transmission is complete.

mode.
Void SCIx_PutBuffer(const unsigned char *PtrToBuffer,
unsigned char NbOfBytes)
Starts transmission from the user buffer. The data trans-
mission will be driven either in Polling or Interrupt driven
mode depending on the mode you selected.
*PtrToBuffer
Start address of the user buffer
NbOfBytes
Number of bytes to be transmitted
None
1. SCIx_Mode must have been called.
2. You must enable the interrupt due to Transmit Data
Ready Flag for the Interrupt driven mode
3. You must select the Polling or Interrupt driven trans-
mission mode in ST7lib_Config.h file.
4. The SCIx_IT_Function must have been called inside
the SCI interrupt subroutine.
SCIx_IsTransmitCompleted
