data buffer ( Use comm_int function call ). Before exiting

 

program, user

must free this buffer ( Use comm_exit function

 

call ).

 

unsigned char port

Specifies communication port (COM1 or COM2)

 

1: COM1 port

 

 

2: COM2 port

 

Return:

Returns a 1 if command succeeds. Returns a 0 if it fails.

comm_get_rec_str

Syntax:

int comm_get_rec_str(unsigned char **data, unsigned char port)

Function Description:

This function call is employed to received string data. The function call returns a success flag if the communication port receives string data ( terminal character is 0x0d) . The function call returns a fail flag if the buffer of the communication port is empty.

Parameter

Description

 

unsigned char **data

Returns the received string contents. User must first allocate a

 

data buffer (Use comm_int function call). Before exiting

 

program, user

must free this buffer (Use comm_exit function

 

call).

 

unsigned char port

Specifies communication port (COM1 or COM2)

 

1: COM1 port

 

 

2: COM2 port

 

Return:

Returns a 1 if command succeeds. Returns a 0 if it fails.

led_init

Syntax:

void led_init()

Function Description:

This function must be called to initialize the ADAM-4500's LED before a user's program can control the LED.

led
