Leave this pin floating

Nettet21. okt. 2013 · If you recall about 2 minutes ago, we don’t want to leave pins floating so in most cases open-drain pins will have an external pullup resistor. If you are tricky (of course, you are), you can configure the MCU’s pull-up resistor and use the pin in open-drain output mode. Nettet5. mar. 2024 · Re: Unused pins on PCB. Since you can use the integrated pull-up and pull-down resistors, you can leave the pin unconnected and be sure to configure/initialize them in your software. Only pins that support both input & output have integrated pull-up and pull-down resistors. Input-only GPIOs 34-39 do not.
