__StartSerialSending
Synopsis transmission>
Boolean __StartSerialSending(unsigned long data, unsigned char wordNum,
unsigned int *SndDtBuf)
data Setup data
wordNum Number of words transmitted
SndDtBuf Pointer to the transmit data
Description Starts transmission of serial communication and writes transmit data to the transmit
buffer by a specified number of words. When transmission of all transmit data is
complete, this API calls a notification function (if a notification function is registered).
[data]
For data, the following values can be set.
RAPI_COM1 UART0 RAPI_COM2 UART1
RAPI_COM3 UART2 RAPI_COM4 SI/O3
RAPI_COM5 SI/O4
Return value If transmission of serial communication was successfully started, RAPI_TRUE is
returned; if failed, RAPI_FALSE is returned.
Functionality Serial I/O
Reference __ConfigSerialDriverNotify , __StopSerialSending
Remark • If an undefined value is specified in the first argument, operation of the API cannot
be guaranteed.
Program example
#include ”rapi_sif_m16c_62p”
unsigned int buffer[10];
void func( void )
{
/* Set 5 word data to transmit buffer of serial communication */
__StartSerialSending( RAPI_COM1, 5, buffer );
}
