GPIO

https://raspberrypi.github.io/pico-sdk-doxygen/group__hardware__gpio.html

Syntaxe	void gpio_init(uint gpio)
Paramètres	gpio numéro de gpio

• gpio_put(LED_PIN, 1);
• gpio_set_dir(LED_PIN, GPIO_OUT);
• gpio_set_pulls (uint gpio, bool up, bool down)

Pwm

• gpio_set_function(PICO_DEFAULT_LED_PIN, GPIO_FUNC_PWM);
• uint slice_num = pwm_gpio_to_slice_num(PICO_DEFAULT_LED_PIN);
• pwm_config config = pwm_get_default_config();
• pwm_config_set_clkdiv(&config, 4.f);
• pwm_init(slice_num, &config, true);
• pwm_set_gpio_level(PICO_DEFAULT_LED_PIN, fade * fade); // rapport cyclique 16 bits
