Module lm4f120::gpio [−] [src]

GPIO for the TI LM4F120H5QR

Supports GPIO, mapping in a UART and putting pins in Timer mode.

Level	Describes what a pin can be set to
Pin	Describes a pin within a port This chip has 8 pins per port.
PinMode	Describes a pin's direction
PinPort	Describes a Port and a single pin within it

enable_ccp	Enable a pin as a Timer Compare pin (e.g. if you want to use it as a PWM output). We assume you've already set it as `PinMode::Peripheral` using `set_direction()`.
enable_uart	Re-configure the pinmuxing so that the given Uart appears on its normal set of pins.
init	init() is empty for now, but it might be needed some day.
read	Read the level of an input pin
set	Set the output value for an output pin
set_direction	Set the direction (input or output) on a given pin in a port
