CCS: Halogen: can.c generated by halcogen, endian conversion for dlc < 4, dlc > 4 and dlc < 8

Hello,

HALCoGen generates can.c file where are the APIs for CAN module.

Inside can.c , s_canByteOrder constant is defined if big endian device is used with correct order of bytes.

Best regards,
Miro

Hi Miro,

Thank you for your reply.
Seen the s_canByteOrder, however I haven't been able to recognise the situation, when dlc < 4, dlc > 4 and dlc < 8.

Hello,

Size of the message is determined from DLC field of the message. In both cases (DLC < 4 and DLC >4), when big endian device is used byte order is defined by s_canByteOrder .

Best regards,
Miro

Hi Miro,


I would have expected the behaviour in attachment.
Please let me know what I have overlooked.

Hi Miro,

Thank you for the specification of the IF registers.
May I ask you to create a HALCOGEN sample project with a received CAN message with a DLC 3?
The goal is convert here the endianness.
