| Description
| This function controls the good read LED.
|
| Syntax
| void goodreadled(int on_off, int time); |
| Arguments
| This parameter can have the following values:
| RED
| Good read RED LED.
|
| GREEN
| Good read GREEN LED.
|
| ORANGE
| GREEN and RED good read LED's on, resulting in an orange color.
|
| RED_FLASH
| Good read RED LED flashing.
|
| GREEN_FLASH
| Good read GREEN LED flashing.
|
| ORANGE_FLASH
| GREEN and RED good read LED's flashing, resulting in an orange flashing color.
|
(The following colors are only available on the OPH100x)
| BLUE
| Good read BLUE LED.
|
| PURPLE
| RED and BLUE good read LED's on, resulting in a purple color.
|
| LIGHT_BLUE
| GREEN and BLUE good read LED's on, resulting in a light blue/green color.
|
| WHITE
| RED, GREEN and BLUE good read LED's on, resulting in a whitish color.
|
| BLUE_FLASH
| Good read BLUE LED flashing.
|
| PURPLE_FLASH
| RED and BLUE good read LED's flashing, resulting in a purple flashing color.
|
| LIGHT_BLUE_FLASH
| GREEN and BLUE good read LED's flashing, resulting in a light blue/green flashing color.
|
| WHITE_FLASH
| RED, GREEN and BLUE good read LED's flashing, resulting in a whitish flashing color.
|
Defines the time the LED is on in steps of 20 milliseconds. After this time the LED will be switched off. For examples, time = 25 specifies half a second. Two values have a special meaning.
| 0
| Good read LED will be switched off immediately.
|
| -1
| Good read LED will be continuously on.
|
|
| Returns
| None
|
| Remarks
| Because the handling of the good read LED is done by the operating system,
the terminal will continue executing the application program, during the time the LED is on. After the 'on-time' period has elapsed, the execution is interrupted in order to switch off the LED. Use the delay() function if you want to halt program execution until the good read LED is switched off again.

| Example
| #include "lib.h"
#include <stdio.h>
void main( void )
{
int x;
while( 1 )
{
for( x=0; x < 10; x++)
{
goodreadled( RED, 25);
delay( 50 );
goodreadled( GREEN, 25);
delay( 50 );
#ifdef BLUE
goodreadled( BLUE, 25);
delay( 50 );
#endif
}
goodreadled( RED, -1);
delay( 200 );
goodreadled( RED, 0);
goodreadled( GREEN, -1);
delay( 200 );
goodreadled( GREEN, 0);
#ifdef BLUE
goodreadled( BLUE, -1);
delay( 200 );
goodreadled( BLUE, 0);
#endif
}
