This file describes the interface of serial port configuration. Serial port means here UART/USART device.

The configuration is the same for input (Receive/Rx) and output (Transmit/Tx).

Definition in file serial.h.

Enumeration Type Documentation

◆ Lz_SerialEnableFlags

enum Lz_SerialEnableFlags

Define flags for enabling/disabling serial transmission/reception.

These flags can be combined using bitwise OR (i.e. | operator).

Enumerator
LZ_SERIAL_DISABLE_ALL	Disable both serial transmission and reception.
LZ_SERIAL_ENABLE_TRANSMIT	Enable serial transmission.
LZ_SERIAL_ENABLE_RECEIVE	Enable serial reception.
LZ_SERIAL_ENABLE_ALL	Enable both serial transmission and reception.

Definition at line 30 of file serial.h.

◆ Lz_SerialStopBits

enum Lz_SerialStopBits

Define the number of stop bits to use on serial line.

Enumerator
LZ_SERIAL_STOP_BITS_1	Use 1 stop bit.
LZ_SERIAL_STOP_BITS_2	Use 2 stop bits.

Definition at line 55 of file serial.h.

◆ Lz_SerialParityBit

enum Lz_SerialParityBit

Define the kind of parity bit to use on serial line.

Enumerator
LZ_SERIAL_PARITY_NONE	Use no parity bit.
LZ_SERIAL_PARITY_EVEN	Use even parity bit.
LZ_SERIAL_PARITY_ODD	Use odd parity bit.

Definition at line 90 of file serial.h.

◆ Lz_SerialSize

enum Lz_SerialSize

Define the size of the character used on serial line.

Enumerator
LZ_SERIAL_SIZE_5	Use 5-bit character size on serial line.
LZ_SERIAL_SIZE_6	Use 6-bit character size on serial line.
LZ_SERIAL_SIZE_7	Use 7-bit character size on serial line.
LZ_SERIAL_SIZE_8	Use 8-bit character size on serial line.

Definition at line 130 of file serial.h.

◆ Lz_SerialSpeed

enum Lz_SerialSpeed

Define the baud rate of the serial line.

Enumerator
LZ_SERIAL_SPEED_2400	Use a 2400 baud rate on the serial line.
LZ_SERIAL_SPEED_4800	Use a 4800 baud rate on the serial line.
LZ_SERIAL_SPEED_9600	Use a 9600 baud rate on the serial line.
LZ_SERIAL_SPEED_19200	Use a 19200 baud rate on the serial line.

Definition at line 175 of file serial.h.

Function Documentation

◆ Lz_Serial_GetConfiguration()

void Lz_Serial_GetConfiguration ( Lz_SerialConfiguration *const serialConfiguration )

Retrieve the configuration of the serial line.

This function will fill the object pointed by the parameter with current serial settings.

Parameters

serialConfiguration A pointer to an allocated Lz_SerialConfiguration (e.g. allocated on the stack).

Definition at line 20 of file serial.c.

◆ Lz_Serial_SetConfiguration()

void Lz_Serial_SetConfiguration ( Lz_SerialConfiguration *const serialConfiguration )

Set the configuration of the serial line.

This function will set the different parameters of the serial line according to the configuration pointed by the serialConfiguration parameter.

Warning: On the AVR platform this function will block interrupts if configuration option LZ_CONFIG_SERIAL_USE_INTERRUPTS is activated. On the AVR platform, this function will wait all transmit and receive operations has completed.
