Error codes of Chardev

[Magnus.Zaza]

I am using CAN Driver and Library API for Linux. This is the output of

Code: Select all

cat /proc/pcan

:

I want to know what the error and the status codes mean. I checked pcan.h file but I can not find 0x000c nor 0x000d (which I got before)
I can find the following error codes:

0x0000 // no error
0x0001 // transmit buffer full
0x0002 // overrun in receive buffer
0x0004 // bus error, errorcounter limit reached
0x0008 // bus error, errorcounter limit reached
0x0010 // bus error, 'bus off' state entered
0x0020 // receive queue is empty
0x0040 // receive queue overrun
0x0080 // transmit queue full
0x0100 // test of controller registers failed
0x0200 // Win95/98/ME only
0x2000 // can't create resource
0x4000 // illegal parameter
0x8000 // value out of range
0x1C00 // wrong handle, handle error

Where to find 0x000c and 0x000d meanings?

Thanks in advance

Hello,

These values are combinations of two or more error codes,

so in your case:

0x000c = 0x0004 & 0x0008

0x000d = 0x0001 & 0x0004 & 0x0008

please read the online help - there you found:

Note that the values of the different PCAN-Status definitions are able to be bitwise combined. In some cases it is possible to get more than one error code as result of calling a function.
