High Speed CAN with F28069 control card

Hi Sneha,

Is it possible to use High-speed CAN with F28069 Experimental kit?

If so what would be the hardware requirements?

If not what other TI processor can be utilised?

F28069 has an eCAN peripheral. You can find the further details about this peripheral in the device's datasheet and TRM:  http://www.ti.com/lit/ug/spruh18e/spruh18e.pdf

Hi gautam

Thanks for the reply.Thats known to me that control card has eCAN ineterface on header pi.My concern is whether high speed CAN with bau`d rates upto 1Mb/sec be used with it and what would be the hardware requirements .Transciever would be required ,120 ohm resistance to terminate ends,any other modem or device to establish two way communication?

Thanks and regards

Yes, transceiver is very much required! Refer this hardware: (just as an example)

Thank you Gautam

You're Welcome! Do keep us informed... and if you feel like the answer was helpful then please don't forget to verify that answer.

Goodluck & Regards,

Gautam

Yes sure.

Once accomplished I will do so.

thanks

Hi gautam

Which CAN transciever would be apt for F28069 experimental kit? SN65HVD255,SN65HVD230...I have to establish communication between sources in a DC microgrid.The DC bus is to operate around 48 V.There are to be sources like PV,Fuel cell,Ultaracapcitor.

Thanks n Regards

Both the parts have their specific feature set. You can start with SN65HVD255 and if you feel its an overkill for your project - downgrade to SN65HVD230.

Thanks

As per the following document 

3005.17.CAN 3.3 or 5V tranciever.pdf

It seems using CAN 3.3V SN65HVD255 would be a better choice.

Sorry correction SN65HVD230 would be a better choice.

Start experimenting then :)

Hi

Assuming that I want to recieve  Signals from four sources using CAN(each source having its own control card) on a f28069 experimental kit,which has only one CANTX/CANrx pin.

can this pin be programed to work with multisources in a loop if not simultaneously  or it can support only one source

thanks

I would like you to go through eCAN peripheral in Technical Reference Manual for F28069. It has ample information on this communication protocol.

Also, you can refer this ppt which is meant for F2812 controller (a very old C2000 mcu); but you can atleast extract some useful info.

NOTE: Please post new questions in a new post. In this way you'll get better responses. If you keep posting and linking questions to the same question then no one other than me would know about your newer questions!

oki

I will take care of this in future.

thanks for your replies.

Sneha

you could use TI development kit DRV8312-69M-KIT. It has a transceiver on it.

Charles, she has already ordered F28069 Experimenter's Kit. I don't know whether she needs a motor kit or not but by doing so she has saved $200 :)

Hi Charles

Thanks for your suggestion.But for my project F28069 is the most suitable and its order is in the process.

thanks

Sneha

This is what we used. it came with C2000 Piccolo TMS320F28069M controlCARD with Isolated XDS100v2 JTAG Emulation.
