Flipper Zero - Write code to blink LED! смотреть онлайн

In this video we write the code to for the Flipper Zero to blink an LED! This is the "Hello World" program of GPIO. The first approach is using gpio_write to turn the GPIO pin on/off. The second approach is used furi_hal_pwm_start to set a frequency and duty cycle to blink the LED. The second approach uses PWM, which is Pulse Width Modulation. The frequency (number of times a second to blink) is a whole number, so this technique only works if you want to blink at least once a second.
