Function Documentation

void led_off

(

)

Send a uart cmd_msg to turn off the LCD's led.

Here is the call graph for this function:

void led_on

(

)

Send a uart cmd_msg to turn on the LCD's led.

Here is the call graph for this function:

void print_msg	(	const char *	buf,
		int	len
	)

Display the string on the LCD's display.

Here is the call graph for this function:

void print_num

(

int

num

)

Display a number on the LCD's display.

Here is the call graph for this function:

void sample_temp

(

)

Send a uart cmd_msg to sample temperature using Raven's on-board temperature sensor. The temperature value will be shown on the LCD.

Here is the call graph for this function:

int serialize_msg	(	cmd_msg_t *	p_msg,
		uint8_t *	buf,
		int	payloadlen
	)

Serialize a cmd_msg structure with its variable payload size specified by payloadlen and copy it into buf.

void uart_send_buf	(	uint8_t *	buf,
		uint8_t	len
	)

Send a preamble and then a stream of bytes synchronously over the UART.
