✨ sunxi-pio ✨

okay bestie, listen up 💖 this is the manual page for sunxi-pio, the little tool that lives in the sunxi-tools world and lets you mess with PIO — that's GPIO and pinmux — on sunxi devices. she's small, she's powerful, she's giving embedded-systems main character energy 👑

🌸 NAME 🌸

sunxi-pio — manipulate PIO (GPIO and pinmux) on sunxi devices 🦋

🎀 SYNOPSIS 🎀

sunxi-pio -m|-i input [ -o output ] pin

like… that's the whole vibe. one input source, optional output file, and a pin. slay 💅

💜 DESCRIPTION 💜

sunxi-pio manipulates PIO (GPIO and pinmux) on sunxi devices ✨

that's it, that's the whole plot. she pokes the pins, she reads the pins, she tells you what the pins are doing. no cap 🌈

👑 OPTIONS 👑

• -m — mmap mode: read the pin state straight from the system, live, no middleman 🧚
• -i — read the pin state from a file instead
• -o — save the pin state data out to a file 💾

and now for the actual pin commands, because this is where it gets fun:

• print — show all pins. every single one. the whole roster 💀
• Pxx — show a single pin, just the one you asked about 🫶
• Pxx<mode><pull><drive><data> — configure the pin. you're setting the whole little ensemble here: mode, pull, drive, data 🌟
• Pxx=data,drive — configure GPIO output 🔥
• Pxx*count — oscillate the GPIO output. yes, wiggle it. and heads up: this one is mmap mode only ⚠️
• Pxx?pull — configure GPIO input 🌸
• clean — clean the input pins 🧼

reminder bestie: Pxx*count only works with -m (mmap mode). don't come for me if it doesn't do the thing otherwise 😭
