Otherwise, the only difference between the applications is the type of filter used in the
design, which is a Capacitor-Inductor-Capacitor (CLC) filter. Capacitors C7 and C9 are both
100 nF, and L1 is 0.1 mH (see
A button is included in the design to enable the user to control the light as it is normally
controlled in dimmer applications, including decreasing or increasing the light’s intensity
(brightness). If the button is pressed quickly (between 0 and 40 ms), nothing happens. If the
time the button is pressed is between 40 ms and 240 ms, the device is turned ON or OFF.
When the lamp is turned OFF, the intensity level is stored in the microcontroller’s memory. If
the time the button is pressed is longer than 240 ms, the device is turned ON and the light
intensity automatically increases until it reaches the maximum limit, and once the maximum
intensity is reached, it automatically decreases (and vice-versa).

Section
The MCU is directly linked to the mains voltage supply. No
insulation is ensured between the accessible parts and the
high voltage. The STEVAL-ILL004V1 evaluation board must
be used with care and only by persons qualified for working
with electricity at mains voltage levels. Certain precautions
have to be taken during emulation to avoid damaging
development tools.
