2020-01-09converter: Improve bit_position computationRomain Forlot1-3/+4
- Fix wrong bit_position swap computed: Need to multiply then lenght in bytes by 8 to get it for bits. - Add a continental bit_position function: This allow to get the correct bit_position using the weird Continental. bit numbering method where the Frame is read using little endianness and bit count using a big endianness - Use define CHAR_BIT instead of hardcoded 8 value Change-Id: I8d458ab457f80e5fa116af942acfceaaef51b763 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>

2020-01-09message: Default frame layout as little endian.Romain Forlot1-1/+1
Change the flags to be enable if frame use big endian rather than little Change-Id: I09ae9c54f1d807da4e740457cf04a001723edb0e Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
2020-01-09decoder: rework how to swap frame layout.Romain Forlot1-5/+8
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/encoder: simplification of code.Romain Forlot1-40/+10
- Useless tests removed - Bit operation changed to more readable ones - Handle correctly mask to decode signal on 1 byte or in-between bytes more clearly. - using static_cast now instead of C casting method. - Avoid manual vector initialization and using default constructors instead. - Avoid using intermediate variables when this isn't necessary.

2020-01-09decoder: Fix bit_position swappingCorentin Le Gall1-1/+2
-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 Bénier1-7/+66
- 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>

2019-08-30Add new decoders bytes for signal of long sizeArthur Guyader1-0/+91
This commit adds the decoder bytes. It allows to return a sequence of bytes in hexadecimal form. Bug-AGL : SPEC-2780 Change-Id: I27180774f044c48a9d7baa2739b15a2e85b8b2e2 Signed-off-by: Arthur Guyader <arthur.guyader@iot.bzh>
2019-08-30Change signature of decodersArthur Guyader1-42/+47
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.

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.

2017-04-14Change directory architecture to use 2 separated projects.Romain Forlot1-233/+0
Each projects, binder and generator, has to be compiled separatly. CAN-binder will host high and low level binding CAN-config-generator only the generator used for low level binding. build.sh script just launch both build in their respective dir.
