Evaluation Software

3 Evaluation Software

Copy the evaluation software (LP5560.exe) and all the included .dll files to your hard drive. The evaluation

software doesn’t need installation and can be run by double-clicking the icon. If the evaluation board is set

up correctly the evaluation software’s user interface should look like Figure 3. The status bar at the right

side of the bottom row should say “connected”. This indicates that the connection between the

microcontroller and the computer's USB interface is working correctly. If the connection fails the status bar

will say “not connected”. In this case check that the evaluation board is connected to the USB port and

that the evaluation board’s jumpers are in the correct places. If the external I/O voltage is used verify that

the I/O voltage is at an acceptable level (between 1.8V to 3.6V).

To start the default blinking sequence, click the Run button and verify that the LED is blinking. Now the

evaluation board is working correctly, and you can start testing different blinking sequences. Stop the

blinking sequence by clicking the Run button again. New blinking sequences can be trained into the

device by selecting the desired on, off, rise and fall times with the sliders. The blinking sequence is trained

into the LP5560 by clicking the Train X Pulses button where 'X' is the number of pulses. Figure 4 shows

the evaluation software after three pulses are trained into the LP5560. Once the Train X button is pressed

a preview of the sequence is shown on the preview window.
