I am working with C in embedded designs and I still use 1 or 0 for a bool certain situations, mostly lines level.

For whatever pea-brained reason, it feels yucky to me to set a gpio to true/false instead of a 1/0.

    GPIOs are usually controlled by a single bit of a register anyway. Most likely you need to do something like:

    // Set high
PORTB |= 1 << PINB5;
// Set low
PORTB &= ~(1 << PINB5);

    I am a lazy dev (not really, clients always want fast code), so I use the provided HAL libraries 99.9% of the time.

    But I have seen code where someone would write something like

    gpio_write(PIN_X, true)

    and it always stood out to me.

    Define on as true or something? Or maybe that's more confusing. I'm not a C dev so I'm not gonna pretend to understand idiomatic microcontroller code lol.
