I am having problems with extended addressing and printing to Glcd. using number to Hex does not display correctly as it does not have the range, example the ID that is being transmited is 127505 which is 1F211Hex hoever Hex to string only prints F211.
Trying to get the extended ID into long variable using GetRXIdent does not seem to give the correct results. As extended can uses 11 bit and an 18Bit address. Somewhere along the line things seem to be wrong maybe its me. Have you a help file somewhere that explains how you get the ID in extended addressing mode.
I have enclosed my test programe.

Re: Can component
Hello. I will raise a bug on the hex-conversion function, and we can make sure it handles 32-bit values in future releases.
As a workaround you could always do:
tmp_string = IntToHex$(id_word)
can_string = IntToHex$(id_word >> 16)
can_string = can_string + tmp_string
This should give you your full 32-bits.
Cheers,
Jonny

Re: Can component
OK using what you have said above
ID=Can1::GetRXIdent(0)
StrIDtp = NumberToHex$ (ID)
Temp = Length$ (StrIDtp)
StrIDtp = Right$ (StrIDtp,temp - 2)
strID = NumberToHex$ (ID >> 16)
strID = strID + StrIDtp
However it returns 0x19F21170 it should return 0x1F211 which is 127505 Dec
Where is extra comming from on Can ID
ID=Can1::GetRXIdent(0)
StrIDtp = NumberToHex$ (ID)
Temp = Length$ (StrIDtp)
StrIDtp = Right$ (StrIDtp,temp - 2)
strID = NumberToHex$ (ID >> 16)
strID = strID + StrIDtp

Re: Can component
Hi
I have managed to get the correct CAN ID by the following
IDLow = ID >> 8
IDHigh = ID >> 24
IdHigh = IDHigh << 14
IDHigh = IDHigh >> 14
StrIDtp = NumberToHex$ (IDLow)
Temp = Length$ (StrIDtp)
StrIDtp = Right$ (StrIDtp,temp - 2)
strID = NumberToHex$ (IDHigh)
strIDHigh = strID
strID = strID + StrIDtp
Is it possible that there is a problem with the CAN component when used in extended addressing mode??
Regards

Re: Can component
Hello,
I'll do some investigation for you on this and see if I can find the cause of the issue.

Re: Can component
Hi Benj
How has investigation on can component going, have you found anything with extended addressing?
