  1. Hoovah thanks for your response. I actually read a lot from your blog (Part 9 where you spoke about the CAN CRC and bucket filling technique). Could you help me precisely on the below 2 questions, I'm trying to find the checksum using the calculator and prove but it doesn't work (like you mentioned). 1.I tried creating a checksum using the CRC calculator (from the payload I sent, I ignored the 7th byte and used the remaining 7 bytes and found a checksum value). I put the checksum on the 7th byte and sent it. I even decoded by finding the checksum (with all the 8 bytes per the J1850), and
  2. Hello, I'm working on a gateway application that will disengage a real ecu and simulate in the software using CAN msgs for automotive. Situation: It looks like the CAN message has a count and a checksum as part of the payload, so every time I change a msg, i need to modify the counter recalculate the checksum. Now in my msg, the checksum is at the 7th byte and the count is in the 8th byte. Ive added below some sample logs collected from the module. So I tried using an online CRC calculator to derive the Polynomial but I'm unable to arrive there. From the below log
