Support for CAN FD is on the wish list. The ShieldBuddy TC375 hardware will support this and the ShieldBuddy TC275 with DC-step silicon is also compatible. The existing CAN driver for the Arduino IDE add-in is based on the Infineon iLLD driver. There is a CAN FD version of the iLLD driver so it would be possible to extend the existing Arduino-style basic CAN driver to support FD.

Hi. Me again
When i try to compile I get this error:

My Mistake, I will use the example to add CANFD to the Global Library, it will take a while but please wait for it I will Share it in here.

g_MulticanFd is something from the original iLLD demo program! It is not essential.

CAN FD

Post by sinai1 on Feb 24, 2021 22:39:42 GMT
Questions:
1.-
canMsgObjConfig.msgObjCount = 1; this is always 1??
2.-
canMsgObjConfig.control.topMsgObjId = 252; this ids need to be unique for each id msj like the msgObjId?
canMsgObjConfig.control.bottomMsgObjId = 253; Same here and why 2 per message?
I find this on the coda so i understand that CANFD need 3 MsgObjts IDs. please confirm.
IfxMultican_MsgObjId topMsgObjId; /**< \brief Specifies the ID of the message object with data byte 8 to 35. (CAN FD) */
IfxMultican_MsgObjId bottomMsgObjId; /**< \brief Specifies the ID of the message object with data byte 36 to 63. (CAN FD) */
Final Question in case my suspicion is rigth we are goind to need more IDs i can have more than 255 IDs on the NO_OFAVAILABLECANMESSAGESLOTS, wich is the maximun?
enum {
MsgObject0, MsgObject1, MsgObject2, MsgObject3, MsgObject4, MsgObject5, MsgObject6, MsgObject7,
MsgObject8, MsgObject9, MsgObject10, MsgObject11, MsgObject12, MsgObject13, MsgObject14, MsgObject15,
MsgObject16, MsgObject17, MsgObject18, MsgObject19, MsgObject20, MsgObject21, MsgObject22, MsgObject23,
MsgObject24, MsgObject25, MsgObject26, MsgObject27, MsgObject28, MsgObject29, MsgObject30, MsgObject31,
MsgObject32, MsgObject33, MsgObject34, MsgObject35, MsgObject36, MsgObject37, MsgObject38, MsgObject39,
MsgObject40, MsgObject41, MsgObject42, MsgObject43, MsgObject44, MsgObject45, MsgObject46, MsgObject47,
MsgObject48, MsgObject49, MsgObject50, MsgObject51, MsgObject52, MsgObject53, MsgObject54, MsgObject55,
MsgObject56, MsgObject57, MsgObject58, MsgObject59, MsgObject60, MsgObject61, MsgObject62, MsgObject63,
MsgObject64, MsgObject65, MsgObject66, MsgObject67, MsgObject68, MsgObject69, MsgObject70, MsgObject71,
MsgObject72, MsgObject73, MsgObject74, MsgObject75, MsgObject76, MsgObject77, MsgObject78, MsgObject79,
MsgObject80, MsgObject81, MsgObject82, MsgObject83, MsgObject84, MsgObject85, MsgObject86, MsgObject87,
MsgObject88, MsgObject89, MsgObject90, MsgObject91, MsgObject92, MsgObject93, MsgObject94, MsgObject95,
MsgObject96, MsgObject97, MsgObject98, MsgObject99, MsgObject100, MsgObject101, MsgObject102, MsgObject103,
MsgObject104, MsgObject105, MsgObject106, MsgObject107, MsgObject108, MsgObject109, MsgObject110, MsgObject111,
MsgObject112, MsgObject113, MsgObject114, MsgObject115, MsgObject116, MsgObject117, MsgObject118, MsgObject119,
MsgObject120, MsgObject121, MsgObject122, MsgObject123, MsgObject124, MsgObject125, MsgObject126, MsgObject127,
NO_OFAVAILABLECANMESSAGESLOTS
};
Example for Init:
void CAN0FD_RxInit(uint32 CAN_Id, uint32 AcceptanceMask, uint8 dlc, uint32 ExtFrame, IfxMultican_MsgObjId MsgObj_Id)
{
/* create CAN node config */
IfxMultican_Can_NodeConfig canNodeConfig;
IfxMultican_Can_Node_initConfig(&canNodeConfig, &g_Multican.drivers.can);
g_Multican.drivers.UserCanRxIds[MsgObj_Id] = CAN_Id;
if (ExtFrame == 11)
{
ExtFrame = FALSE;
}
else
{
ExtFrame = TRUE;
}
/* create message object config */
canMsgObjConfig.msgObjCount = 1;
canMsgObjConfig.control.topMsgObjId = 252;
canMsgObjConfig.control.bottomMsgObjId = 253;
/* Destination Message object */
{
/* create message object config */
IfxMultican_Can_MsgObjConfig canMsgObjConfig;
IfxMultican_Can_MsgObj_initConfig(&canMsgObjConfig, &g_Multican.drivers.canNode0);
canMsgObjConfig.msgObjId = MsgObj_Id;
canMsgObjConfig.messageId = CAN_Id;
canMsgObjConfig.acceptanceMask = AcceptanceMask;
canMsgObjConfig.frame = IfxMultican_Frame_receive;
canMsgObjConfig.control.messageLen = IfxMultican_DataLengthCode_64;
canMsgObjConfig.control.extendedFrame = ExtFrame;
canMsgObjConfig.control.matchingId = TRUE;
canMsgObjConfig.control.fastBitRate = FALSE; /* fast bit rate enable/disable */
/* initialize message object */
IfxMultican_Can_MsgObj_init(&g_Multican.drivers.UserCanMessages[MsgObj_Id], &canMsgObjConfig);
}
}

Hi Sinai1, can you clarify which AURIX you are using, TC275 or TC375? The reason for asking is because the CAN module is completely different on the TC375.
