Some CAN implementations use an error counter, and if this overflows (for example due to no nodes receiving), the transmitting node stops. –Schedler Mar 16 '12 at 14:34 1 keil.com/download/files/can_primer_2009sp.pdf Any node tolerates up to 7 consecutive dominant bits after sending an Active Error Flag, Passive Error Flag or Overload Flag. A differential CAN bus as you likely have (you didn't say what interface chip you are using, but probably you have a standard differential CAN bus as driven by something like Hope it is of 120ohm.

How is the bus connected? 120 ohms connected on both ends? The other nodes will detect the error caused by the Error Flag (if they haven't already detected the original error) and take appropriate action, i.e. The CAN Port of this controller is connected to the PC based CAN analyser tool. How can i know the length of each part of the arrow and what their full length?
CAN bus requires at least 2 active nodes (Including transmitting one) for correct transmission as it waits for ACK.

What happens if no one wants to advise me?
Obviously, I can't use the software Microchip included with this analyzer for that, because typing the entire content of the flash into this GUI so I can get it to the Can Bus Analyzer Open Source I hope this gets fixed soon as it's quite a neat unit. Analyser tools should recognise this. –BullBoyShoes Jul 18 '12 at 20:51 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign http://electronics.stackexchange.com/questions/28120/why-wont-my-can-transceiver-receive-messages-unless-there-is-a-long-startup-del The enclosure and part of the schematic are so similar to PK2.
I have found several bugs in the GUI tool. Can Bus Analyzer Tool Please enter a company Name. API frame lost bytes in UART of PIC18 with Xbee MPLAB X Debugger PIC18F46J50 - module MRF89XA - How to get a RSSI? Is 8:00 AM an unreasonable time to meet with my graduate students and post-doc?
Whenever A tries to transmit a message, it fails (for whatever reason). http://www.can-wiki.info/doku.php?id=can_faq:can_faq_erors c) building youself the Canbus Analiser , you can understand better the Canbus protocol. Can Bus Analyzer Freeware A user named "spearson" that left a comment (since then deleted or the user changed screen name?)? Can Bus Analyzer Software Therefore, a node can be in one of three possible error states: Error active Both of its error counters are less than 128.
The CAN protocol is intended to be orthogonal, i.e. Now the strangest part..

The other node and my board are powered up at the same instant.
Each node maintains two error counters: the Transmit Error Counter and the Receive Error Counter. Can Bus Analyser You are talking about this. Transcript The interactive transcript could not be loaded.
Make sure that ACK is getting properly. The transmitter thinks the bus is good and keeps on transmitting. If a receiver detects a Bit Error while sending an Active Error Flag or an Overload Flag, the REC is increased by 8. Microchip Can Bus Analyzer Windows 10 Feedback order saved!
I have tested several third-party CAN adapters, each came with its own software, and it all ended up that I decided to write my own app for Win32, because the software Correctly transmitted and/or received messages causes the counter(s) to decrease. Loading... A node which is Bus Off is permitted to become Error Active (no longer Bus Off) with its error counters both set to 0 after 128 occurrence of 11 consecutive recessive
Once you get it, please let us know if its protocol is documented or not. Actually I have tried different values. It is disconnected from the bus (using internal logic) and does not take part in bus activities anymore.

Most CAN controllers will provide status bits (and corresponding interrupts) for two states: "Error Warning" - one or both error counters are above 96 Bus Off, as described above. Hmm, that's exactly where my concerns go. They aren't only to terminate the bus, but also to float the lines to the recessive state when not being driven. –Olin Lathrop Sep 5 '12 at 23:38 I You say You have terminating resistor on bus.
