2020-01-09decoder: rework how to swap frame layout.Romain Forlot1-4/+0
This also change the bit_position to retrieve the bit word starting from the left or the right of the frame depending on the endianness of the frame layout. Change-Id: I28658e9d46bd35d8ecabeece317331832229384a Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
2020-01-09decoder: Fix bit_position swappingCorentin Le Gall1-0/+4
-Added an attribute to signals that tells if the bit_position has been swapped. -Test if bit_size and bit_position gives an "out of range" data Bug-AGL: SPEC-3022 Change-Id: I589565ca923ec807da2d4f0db7c4c92fb737b579 Signed-off-by: Corentin Le Gall <corentin.legall@iot.bzh> Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
2020-01-09sign: handle decode methods sign from can valueClément Bénier1-3/+14
- add enumeration that represents the way of encoding: enum sign_t { UNSIGNED = 0, SIGN_BIT = 1, ONES_COMPLEMENT = 2, TWOS_COMPLEMENT = 3, SIGN_BIT_EXTERN = 4 }; - the function handle_sign allows to transform value if negative and return the sign of the value in order to be multiplied at the end ot the parcing Bug-AGL: SPEC-3021 Change-Id: I5766a286488170d930422474b4c4f3a8578ca726 Signed-off-by: Clément Bénier <clement.benier@iot.bzh> Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
2020-01-09can: Add big endian CAN frame layout handleCorentin Le Gall1-0/+1
- can-decoder.cpp: translate_signal() : Tests "frame_layout_is_little". If false the signal's bit position is changed to fit the layout. - message-definition.cpp: Added the new attribute "frame_layout_is_little" and its getter. - signals.cpp: Added a setter to the bit_position attribute. - converter.cpp: Added a methode to convert a big endian bit_position to a right (little endian) bit_position.

2019-08-30Change signature of decodersArthur Guyader1-4/+2
This commit changes the signature of decoders. It is now necessary to specify the version of the signals so that the low-can-generator generates the associated wrapper and not need to modify the decoder already developed.

2019-06-26Rename some of the classes removing can- prefixRomain Forlot1-0/+177
This commit renames files and classes : - can_message_definition_t -> message_definition_t - can_message_set_t -> message_set_t - can_signals_t -> signals_t This prepares the implementation of j1939 protocol.
