LED Controller Peripheral
This peripheral is applicable to IS31Fl3216 chip that is a light LED controller with an audio modulation mode. It can store data of 8 Frames with internal RAM to play small animations automatically.
You can also use it to control a number of LEDs connected to GPIOs. If you want to use the IS31Fl3216, see functions periph_is31fl3216_init()
, periph_is31fl3216_set_blink_pattern()
, periph_is31fl3216_set_duty()
, periph_is31fl3216_set_state()
.
Application Examples
Implementation of this API is demonstrated in checks/check_display_led example.
