Hello, ok. Just to sum up: In order to get the best accuracy on filtering you need to do two things: Limit the hardware filter as good as possible, using FilterMessages or SetValue(PCAN_ACCEPTANCE_FILTER_XX). This decreases the amount of messages received by the the hardware. Use additional software...

Hello, as Marvin already said, this is due to the way how the CAN controller sets the filter. It cannot be guaranteed that you exactly receive the messages you entered. The filter is set using a 32 bit acceptance mask and 32 bit acceptance code. The bits that stay as "don't care" can take any form, ...

Hello, not sure why you ask again the same. I already told you how to get such messages 1.I used UDS_Read() API to read it ,but it's failed. you need to create a mapping to get them as UUDT frames. 2.I used PCAN-Basic Read() API to read it ,it's successful to read the message,but need take a long ti...

Hello, you should not use UDS and PCAN-Basic within the same channel for reading. Note that UDS is using the PCAN-Basic channel internally for communication, so that any message you read with PCAN-Basic will not be available for UDS , which leads to communication problems. If you need to read CAN me...

Hello, I understand that sometimes one can make a mistake by reading. When you are looking for losing a problem it is always good to read possible solutions carefully and, more important, to understand the problem. The first answer from our team contained already the solution for your problem, as we...

Hello, It seems like the frequency of the time stamps in the trace file in the same no matter how often I call CAN_Read() Just to read a message "later" doesn't mean that they will change their timestamps. You need to understand more how CAN works. To be clear, what I really want is less frequent da...

Hello, then you just need to call CAN_Read less frequently. Each call to the CAN_Read function will return just one message, so you can use a timer, set its interval to the frequency you want to read and call the CAN_Read function each time the time elapses. But keep in mind that doing so could lead...

Hello, this is no possible. Writing in the trace file occurs only when a message is read. Since PCAN-Basic doesn't read messages actively, but only when you call the function CAN_Read, or CAN_ReadFD (according to your configuration), you cannot adjust a time for flushing data. The only thing you cou...

Hello, this is normal that your receive those 29-bit frames. PCAN-ISO-TP is configured like that. You can see this in the chapter 4.4 of the documentation for PCAN-ISO-TP v2.x (page 116): ISO-TP_Mappings.PNG Note that there are no mappings needed in order to receive FIXED_NORMAL or MIXED 29-bit mess...

Hello,

all our Apis are thread-safe, so yes, it is not a problem calling the function from different threads.
