Parameters
The lower speeds help support Plug & Play.
Serial_Init()
Configure the communication speed, flow control, character parity and number of
stop bits. The serial interrupt service routine is NOT maskable, the interrupt vector is
set internally, so using Set_Event (eSerial, ...) will not have any effect. The baud
rates listed below are available for specific CPU clock speeds only. Review the
API_Struct_12.h for more information.
Bbool Serial_Init (
Speed: Input parameter
This selects the communication speed. Possible values are:
Parity_enb: Input parameter
Specifies if the exchanged characters contain a parity bit (TRUE) or not (FALSE).
parity: Input parameter
Specifies if the characters parity bits must be odd (TRUE) or even (FALSE).
Two_stop_bits: Input parameter
Specifies if the exchanged characters contain two stop bits (TRUE) or one (FALSE).
xon_xoff: Input parameter
Specifies if Xon_Xoff control is on (TRUE) or off (FALSE).
Setup the Tx buffer before sending data to the PC UART. An application should call
this API immediately after calling Serial_Init().
enum SERIAL_RC data *Serial_Tx ( U08x xdata *buffer, U16 len )
buffer: Input parameter
Specifies a pointer to the data buffer containing data to send to the PC UART.
