Evaluation Software Controls

4.11 Reset Button

The Reset button resets the device to factory defaults.

4.12 Run Button

The Run button sets the CTRL pin high. This sets the LP5560 to Run mode. The CTRL pin stays high

until the Run button is clicked again. While the Run button is active all other control buttons are disabled.

4.13 Run Once 1 Button

The Run Once 1 button generates a Run Once command (see LP5560 Programmable LED Driver with

Single-Wire Interface (SNVS873)) and leaves CTRL high. The LP5560 generates the programmed

blinking sequence only once. The CTRL line remains high until the Run Once 1 button is clicked again.

While the Run Once 1 button is active all other control buttons are disabled.

4.14 Run Once 2 Button

The Run Once 2 button generates a Run Once command (see LP5560 Programmable LED Driver with

Single-Wire Interface (SNVS873)) and leaves CTRL low. After this, click the Run button to trig the blinking

sequence. Once the Run button is clicked, the device generates the programmed blinking sequence only

once.

4.15 Follow Mode 1 Button

The Follow Mode 1 button sets the LP5560 into Follow mode. In Follow mode the LED stays on as long

as CTRL is held high, and Rise Time 1 and Fall Time 1 settings are used to ramp the LED current up and

down. To turn the LED to turn on and off without ramps, first train a sequence with Rise Time 1 and Fall

Time 1 settings at zero, then set the device into Follow mode.

4.16 Follow Mode 2 Button

The Follow Mode 2 button sets the LP5560 into Follow mode and reprograms the Rise Time 1 and LED

current settings.
