Hi,

I am new there, but hoppe to find a help.

I have two Challenges.

2. I want to add one bit on the message I receive and send it back on other ID

example:

Read ID 0001   6    12 14 45 67 58 10
send ID 0002   8    12 14 45 67 58 10 01 00

send ID 0003   8    23 34 56  45 45 23 23  24

Thank you!

Re: Sending several CAN ID

The CAN bus is a serial data bus. You can't send several messages simultaneously. But you can send several the messages one by one like in attached example.

Hi,

It looks like that I have some other issue wit it.

Is it possible to make, that ID 0003 is send with separate frequency?

ID002 is send the same frequency like  ID 001 is received. But in the system 001  is every 1000 ms, but 003 has to be received every 200 ms.

thanks !
