Example 5:
To make the Red LED of 1 Hz blink for 3 times. After that, resume to initial state.
// Assume the Red LED is initially
OFF
, while the Green LED is initially
ON
. //
// The Initial Red LED Blinking State is
ON
. Only the Red LED will be blinking.
// The buzzer will turn on during the T1 duration, while the Green LED will turn off during both the T1
and T2 duration.
// After the blinking, the Green LED will turn
ON
. The Red LED will resume to the initial state after the
blinking //
1 Hz = 1000 ms Time Interval = 500 ms ON + 500 ms OFF
T1 Duration = 500 ms = 05h
T2 Duration = 500 ms = 05h
Number of repetition = 03h
Link to Buzzer = 01h
APDU = “FF 00 40 50 04 05 05 03 01”
Response = “90 02”
Example 6:
To make the Red and Green LEDs of 1 Hz blink for 3 times.
// Assume both the Red and Green LEDs are initially OFF. //
// Both Initial Red and Green Blinking States are ON //
// The buzzer will turn on during both the T1 and T2 duration//
