Hi,
I have asked questions about CAN sending before, but they have not been solved.
I try to send a message object and delete the message object,but a stack error occurred!
My code for CAN send message object is as follows:
u8 mcal_CanSendByte(u8 bCanIndex,u32 uMsgId,CAN_IdType pIdType,u32 uDataLen,u8 pData[8])
{
u8 retVal = 1; /***设置返回值并初始化***/
u8 uDataIdx = 0;
CAN_DCANData uTxData;
memset(&uTxData,0,sizeof(uTxData));
pTxMsgObjectParams.msgIdentifier = uMsgId; /*设置传输消息ID*/
if(pIdType == The_Standard_Frame)
{
pTxMsgObjectParams.xIdFlag = CAN_DCANXidType_11_BIT; /*标准帧标识*/
}
else if(pIdType == The_Extend_Frame)
{
pTxMsgObjectParams.xIdFlag = CAN_DCANXidType_29_BIT; /*扩展帧标识*/
}
/***创建CAN-TX传输消息实体***/
pTxMsgObjHandle = CAN_createMsgObject (s_pCanHandle, 64, &pTxMsgObjectParams,&s_pErrCode);
uTxData.dataLength = uDataLen; /*设置TX传输消息的数据长度*/
for(uDataIdx = 0;uDataIdx < uDataLen;uDataIdx++)
{
uTxData.msgData[uDataIdx] = pData[uDataIdx];/*复制数据*/
}
/***发送通过参数传入的消息对象，并判断是否发送成功：若发送失败则将该消息入队，并修改返回值为0***/
if(0 != CAN_transmitData(pTxMsgObjHandle,&uTxData,&s_pErrCode))
{
retVal = 0; /***发送失败,重设返回值0***/
}
CAN_deleteMsgObject(pTxMsgObjHandle,&s_pErrCode);
}
Did I make a mistake somewhere? If I don't delete the message object after sending (CAN_deleteMsgObject(pTxMsgObjHandle,&s_pErrCode);), the error will not appear and the program will execute!
Please help me.
Thank you,
Yaowei
