minus-squareCroquette@sh.itjust.workslinkfedilinkarrow-up6·18 hours agoI 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.
minus-squarexthexder@l.sw0.comlinkfedilinkarrow-up6·edit-217 hours agoGPIOs 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);
minus-squareCroquette@sh.itjust.workslinkfedilinkarrow-up2·15 hours agoI 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.

minus-squareCroquette@sh.itjust.workslinkfedilinkarrow-up1·2 hours agoSometimes, people do that. But using 0/1 is explicit enough since you can refer to a line as ‘1’ or ‘0’ for high/low on the hardware as well
