4 Evaluation Software Controls

The LP5560 is a programmable LED driver that can generate a variety of blinking sequences with up to

three pulses of a different length per pulse. Blinking sequences can be programmed through a single-wire

interface. Programmable parameters include on and off times as well as rise and fall times. The LED

current can also be set through the single-wire interface. Evaluation software can control all programmable

parameters of LP5560.

4.1 Calibration Pulse Slider

The Calibration Pulse slider controls the calibration pulse length. Calibration pulse can be set from 500 µs

to 10 ms. The indicator on the right side of the slider shows the selected value.

4.2 LED Current Slider

The LED current slider controls the LED current. A new current can be trained into the device with the

Change Current button or together with a new blinking sequence. The indicator on the right side of the

slider shows the selected value.

4.3 Rise Time X Slider

The Rise-Time slider sets the LED current rise time for pulse X. Rise time can be set from 0 to 1584 ms.

Each pulse has its own rise time control. The indicator on the right side of the slider shows the selected

value.

4.4 On Time X Slider

The On-Time control sets the LED on time for pulse X. On time can be set from 13.2 ms to 3009.6 ms.

Each pulse has its own on-time control. The indicator on the right side of the slider shows the selected

value.

4.5 Fall Time X Slider

The Fall-Time slider sets the LED current fall time for pulse X. Fall time can be set from 0 to 1584 ms.

Each pulse has own fall-time control. The indicator on the right side of the slider shows the selected value.

4.6 Off Time X Slider

The Off-Time control sets the LED off time for pulse X. On time can be set from 26.4 ms to 6019.2 ms.

Each pulse has own on-time control. Indicator on the right side of the slider shows the selected value.

4.7 Train 1 Pulse Button

The Train 1 Pulse button generates a training sequence for one pulse. Once the button is clicked a

preview window is updated.

4.8 Train 2 Pulses Button

The Train 2 Pulse button generates a training sequence for two pulses. Once the button is clicked a

preview window is updated.

4.9 Train 3 Pulse Button

The Train 3 Pulse button generates a training sequence for three pulses. Once the button is clicked a

preview window is updated.

4.10 Change Current Button

The Change Current button changes the LED current without changing the previously trained blinking

sequence. If the device is in Follow mode, it remains in Follow mode, but the current changes.
