TMS320F28035: CAN Bus without Transceivers using eCAN

Ahmed Eltahan

Part Number: TMS320F28035

I have the same problem with my board. I am asking that if you connected the CAN using the resistor diode method, did it work?, What are your preferences for their values? and Pin Configuration (Pull or open drain..etc for the RX and the TX)

Thank you.

It is likely the methods suggested in the other thread would work, but is important you test them under all operating conditions. Just out of curiosity, how many nodes are you trying to connect?

I am trying to connect only 2 nodes.

Ahmed,

I just showed the reference circuit to my customer and they did not have any further question later.

I am not sure if they follow it up exactly and what values they use.

Ahmed,

As mentioned in my previous post, the suggested methods should work. Since I haven't tried or tested those ideas myself, I am unable to provide guidance on what values to use. Sorry I am unable to help you in this matter.
