Hello Texas instrument forum,
I found a problem with the can bus and transceiver SN65HVD230DR
Currently, I have not found the origin of this problem for that I will share with you my problem and if you have encountered this problem or you have ideas to solve it, I will be thankful to help me –
- First of all, the can bus architecture is as follows
- I work with the transceiver SN65HVD230DR under this diagram
- When I made the diagnosis in case all the controllers are mounted, I found this signal curve where disturbances are superimposed with the signal
- During my investigation I found that when I decreased the number of controllers from 4 down to just 2 (of course both controllers which 120-ohm resistor are mounted I didn't touch) the signal becomes smooth like the following capture
So my problem that I did not manage to touch the origin of this problem and I am at your disposal for any other information and of course I am open to any proposed solution to discuss.
