Function Documentation

void Serial_flush

(

void

)

Flushes the serial port receive buffer.

It will block until it gets something to receive

Definition at line 45 of file serial.c.

Here is the caller graph for this function:

void Serial_init

(

void

)

Initializes the serial port.

Currently, the port is set to 8N1 and the baud rate specified by MYUBRR. This function also enables the receiver interrupt.

Definition at line 13 of file serial.c.

Here is the caller graph for this function:

uint8_t Serial_needsreading

(

void

)

Returns 1 if there is something to be read from the serial port, zero otherwise.

Definition at line 66 of file serial.c.

uint8_t Serial_receive

(

void

)

Retrieve a byte from the receive register.

Will block until there is something to be retrieved

Definition at line 35 of file serial.c.

Here is the caller graph for this function:

void Serial_send

(

uint8_t

c)

Sends a byte through the serial port.

Definition at line 72 of file serial.c.

Here is the caller graph for this function:

void Serial_send1

(

uint8_t

c)

Definition at line 82 of file serial.c.

Here is the call graph for this function:

void Serial_send2	(	uint8_t	c1,
		uint8_t	c2
	)

Sends 2 bytes through the serial port.

Definition at line 89 of file serial.c.

Here is the call graph for this function:

void Serial_send3	(	uint8_t	c1,
		uint8_t	c2,
		uint8_t	c3
	)

Sends 3 bytes through the serial port.

Definition at line 97 of file serial.c.

Here is the call graph for this function:

Here is the caller graph for this function:

void Serial_send4	(	uint8_t	c1,
		uint8_t	c2,
		uint8_t	c3,
		uint8_t	c4
	)

Sends 4 bytes through the serial port.

Definition at line 106 of file serial.c.

Here is the call graph for this function:

void Serial_send5	(	uint8_t	c1,
		uint8_t	c2,
		uint8_t	c3,
		uint8_t	c4,
		uint8_t	c5
	)

Sends 5 bytes through the serial port.

Definition at line 117 of file serial.c.

Here is the call graph for this function:

void Serial_send6	(	uint8_t	c1,
		uint8_t	c2,
		uint8_t	c3,
		uint8_t	c4,
		uint8_t	c5,
		uint8_t	c6
	)

Sends 6 bytes through the serial port.

Definition at line 129 of file serial.c.

Here is the call graph for this function:

Here is the caller graph for this function:

void Serial_sendarr	(	const uint8_t *	arr,
		uint8_t	len
	)

Sends an array of bytes through the serial port.

Parameters

[in]	arr	Array of bytes to send
[in]	len	Number of bytes to send
