Description
The periphery abstraction layer (periphAL) should be revised and optimized:
- All
enum
should be replaced by a combination of#define
and optimal fundamental types (e.g.typedef uint16_t apalExitStatus_t
) for best code efficiency. apalGpioActive_t
should be extended by two further states:APAL_GPIO_ACTIVE_NONE
andAPAL_GPIO_ACTIVE_ANY
apalGpioEdge_t
documentation s´must clearly state that values refer to physical (not logical!) signal edges.apalGpioMeta_t
needs to be updated accordingly (i.e. two bits for theapalGpioActive_t
member).- The
edge
member ofapalGpioMeta_t
can also apply to output signals, so wherever this struct is used, comments must be updated accordingly (right now the definitions in allmodule.c
files state it as "interrupt edge", which just one of many ways how the edge information can be interpreted).
History
#1 Updated by Thomas Schöpping almost 5 years ago
- Status changed from New to Resolved
- % Done changed from 0 to 100
- Estimated time changed from 4.00 to 8.00
The structure of periphAL was heavily revised.
In addition to the requested enhancements, the interface header is now a fixed component of AMiRo-LLD, thus it is not required that the using OS implements this header.
