This sketch increases the luminosity of the built-in LED of the Digispark.
|
||||
When the luminosity reaches its maximum, the luminosity decreases.
|
||||
When the luminosity reaches its minimum, the luminosity increases, and so on...
|
||||
|
||||
Note:
|
||||
====
|
||||
Declare the Pin(s) used in "librarie/TinySoftPwm/TinySoftPwm.h"
|
||||
In this sketch, #define TINY_SOFT_PWM_USES_P1 must be enabled (not commented) since it uses the DigiSpark built-in LED wired on P1.
|
||||
|
||||
In this basic example, TinySoftPwm_process() is called periodically using micros(), but it is recommanded to call it from a timer ISR
|
||||
to ensure a better periodicity.
