Len: Input parameter.
Specifies the current number of bytes to be sent.
Return Codes
S_EMPTY
Successful transmission.
S_PENDING,
Successful transmission thus far but not yet finished.
Where return code SERIAL_RC is defined as: Enum SERIAL_RC.
Serial_CTx()
Purpose
Put bytes into the transmit buffer and start sending. Prior to calling this function,
Serial_Tx() must be call to setup the Tx buffer.
Synopsis
Unsigned Integer Serial_CTx ( U08x xdata *buffer, U16 len )
Parameters
buffer: Input parameter
Specifies a pointer to the data buffer containing the data to send to the PC UART.
len: Input parameter.
Specifies the current number of bytes to be sent.
Return Value
Unsigned integer specifying the number of bytes sent thus far.
After calling this API, an application can make sure all bytes were transmitted by checking that
Serial_TxLen() returns a 0.
Serial_TxLen()
Purpose
Number of bytes transmitted thus far.
Synopsis
Unsigned integer Serial_ TxLen ( void )
Parameters
none.
Return Value
Unsigned integer specifying the number of bytes left in the Tx buffer, i.e. the
remaining bytes to be sent.
Serial_TxByte ()
Purpose
Send a quick byte out.
Synopsis
void Serial_TxByte ( U08 cbyte )
Parameters
cbyte: Input parameter
Byte to put at the end of the Tx buffer to be sent out quickly.
Return Codes
none.
This function performs similarly to Serial_CTx() ( U08 &cbyte, 1) but it has much less overhead. Use this
API when performance optimization is required yet only one byte can be sent at a time.
Serial_Rx()
Purpose
Setup receive buffer and start receiving. Always call this function after Serial_Init() to
make sure the receive buffer is available.
Synopsis
enum SERIAL_RC data *Serial_Rx ( U08x xdata *buffer, U16 len )
Parameters
buffer: Input parameter
Specifies a pointer to the data buffer to store the data received from the PC UART.
