io

Interactive expansion I/O manager. Its default Layout view presents the board's connectors in their physical arrangement, followed by the existing pin, named-bus, and resource-claim views. It uses the same ownership and validation services as the gpio, i2c, spi, uart, onewire, and expansion commands.

Usage:

io

Controls:

• Tab switches between Layout, Pins, Buses, and Claims. Outside Layout,

Left and Right also switch views.

• Arrows move through the physical connector grid in Layout and through rows

in the other views. Page Up/Page Down, Home, and End make larger moves.

• Layout adapts to the terminal: compact headers show several pins across,

while long headers such as the DevKitC J1/J3 pair scroll vertically with one physical pin pair per row.

• Layout markers are * free, ~ releasable, @ claimed, ! fixed/control,

+ power, - ground, and x not connected.

• Enter opens context-sensitive actions for a pin or bus.
• n creates a board-approved named I2C, SPI, UART, or 1-Wire bus.
• Bus creation uses arrows to select fields and values; the generated bus name

can be edited directly.

• Runtime buses can be attached, detached, or removed when their lease state

permits it. Their Autostart action idempotently appends the matching expansion bus create ... command to /.shell/startup. Direct GPIO and PWM assignments can be created and released from the Pins or Layout view.

• r refreshes; q, Esc, or the app-exit key exits.
