write to a pin 'manually'

the pin GPIO number is not the index of the pin if you look at the pins as a (2x10) matrix

            let n_gpio_number = 0;

make sure to apply theese operations to the pin first note , all of the functions are async and have to be awaited to finish completly

'export'

            await o_mod.f_pin_export__from_n_gpio_number(n_gpio_number);

'direction'

            await o_mod.f_pin_set_direction__from_n_gpio_number(
                n_gpio_number, 
                o_mod.s_pin_direction_out
            );

'state'

we can now write the state high or low to the pin

            await o_mod.f_pin_set_state__from_n_gpio_number(
                n_gpio_number,
                o_mod.s_pin_state_high // 'high' or 'low'
            )

reading a pin

            await o_mod.f_pin_export__from_n_gpio_number(n_gpio_number);
            await o_mod.f_pin_set_direction__from_n_gpio_number(n_gpio_number, o_mod.s_pin_direction_in);
            let n = await o_mod.f_n__pin_get_state__from_n_gpio_number(n_gpio_number)
            console.log(n)//0 or 1

write to a pin 'automatically'

get the raspberry pi (version 1 or version 2)

            let o_raspi__v2 = o_mod.o_raspi__v2;

get the desired pin

            let o_pin__gpio_3 = o_raspi__v2.a_o_pin.find(o=>o.n_gpio_number == 3);
            let o_pin__gpio_5 = o_raspi__v2.a_o_pin.find(o=>o.n_gpio_number == 5);
            await o_mod.f_v_pin_getorset_state__from_o_pin(
                o_pin__gpio_3,
                o_mod.s_pin_state_high // 'high' or 'low'
            );
            let n_state__pin_5 = await o_mod.f_v_pin_getorset_state__from_o_pin(
                o_pin__gpio_5,
            );

some available data microseconds since script start , v->value (can be null), n-> number

            // wpn -> window.performance.now(), microseconds since start of script at when the state
            // of the pin was written last (does not depend on if the pin state has changed since last write)
            console.log(o_pin__gpio_3.v_n_mics_wpn__last_write) // eg. 4194.229476
            // microseconds since start of script at when the state
            // of the pin was written last where the state changed
            console.log(o_pin__gpio_3.v_n_mics_wpn__last_write_where_state_chaned) // eg. 5002.229476
