[−][src]Enum rppal::gpio::Error
Errors that can occur when accessing the GPIO peripheral.
Variants
UnknownModel
Unknown model.
The Raspberry Pi model or SoC can't be identified. Support for new models is usually added shortly after they are officially announced and available to the public. Make sure you're using the latest release of RPPAL.
You may also encounter this error if your Linux distribution doesn't provide any of the common user-accessible system files that are used to identify the model and SoC.
PinNotAvailable(u8)
Pin is not available.
The pin is already in use elsewhere in your application, or the GPIO peripheral
doesn't expose a pin with the specified number. If the pin is currently in use, you
can retrieve it again after the Pin
(or a derived InputPin
, OutputPin
or
IoPin
) instance goes out of scope.
PermissionDenied(String)
Permission denied when opening /dev/gpiomem
, /dev/mem
or /dev/gpiochipN
for
read/write access.
More information on possible causes for this error can be found here.
Io(Error)
I/O error.
ThreadPanic
Thread panicked.
