General • Re: RP2040 counter divider by 10

About PIO, I found only such an example for output. Can someone give you a link to an input example?
I have no idea how it works, but it's very likely true.

Code:

// Output PWM signals on pins 0 and 1#include "pico/stdlib.h"#include "hardware/pwm.h"int main() {    // Tell GPIO 0 and 1 they are allocated to the PWM    gpio_set_function(0, GPIO_FUNC_PWM);    gpio_set_function(1, GPIO_FUNC_PWM);    // Find out which PWM slice is connected to GPIO 0 (it's slice 0)    uint slice_num = pwm_gpio_to_slice_num(0);    // Set period of 4 cycles (0 to 3 inclusive)    pwm_set_wrap(slice_num, 3);    // Set channel A output high for one cycle before dropping    pwm_set_chan_level(slice_num, PWM_CHAN_A, 1);    // Set initial B output high for three cycles before dropping    pwm_set_chan_level(slice_num, PWM_CHAN_B, 3);    // Set the PWM running    pwm_set_enabled(slice_num, true);    // Note we could also use pwm_set_gpio_level(gpio, x) which looks up the    // correct slice and channel for a given GPIO.}
