CAN_LDD usage

[serhatitu]

Hello,

Is anyone know how to use Can_Ldd component?

how can i communicate with another devise which supports CAN using can_ldd bean?

Is real time operasting system necessary for can comm?

i need one example about can comm?

thanks

Hello Petr,

i have already tried demo project. It worked successfully.It is simple because no need another CAN node, so no need any reception.

i need working CAN example code from node to node, not loopback example.

why i can not find any example except loopback example?

Could you please send another example?

Hi,

I currently don't have any other project. However, it should be quite simple to change the CAN demo project to work between two boards.

Open the inspector if the CAN_LDD component and change the 'Loop mode' property  to 'no'. Then re-generate the code, build  and run the project.

The communication will be performed via selected RX and TX pins and you can interconnect two boards.

How about the codes Petr?

Should i upload same codes to two boards, i think it must be different.

In loopback example it is sending  and also receiving data itself. Therefore i think uploading same code to two boards will cause problem.

Yes, you are right, I have described only component setup. You need to duplicate the projects and slightly modified code for both boards.

For the first try, it should work to just remove the stroke-through lines and keep only receiver part in receiver project and transmitter part for transmitter according to this picture:

Hi Petr,

I would like to create CAN communication between two kinetis k60D100M board. I already create 2 different project, CAN Transmit and CAN Receive. But when I'm trying to run the project, it seems to be not working. Is there any hardware configuration (jumper) should I made? Thanks for you help.

Hi agungdeffendi

I have met the same problem. If you fix it please share your solution.

Thanks.

Thanks Petr ,

i am using TWR-K60512 i have another board including same mcu.(MK60DN512Z)

i can not communicate each other using CAN_LDD. i have already looked help document

could you send an example ?

Hi,

There is a ready to use simple loop-back example project within the Processor Expert installation.

If you are using CodeWarrior, find it at {CW_for_MCUs}\MCU\CodeWarrior_Examples\Processor_Expert\Kinetis\TWR-K60N512\CAN

If you are using PEx driver suite, you can find it at {PEx_drv_suite}\eclipse\ProcessorExpert\Projects\TWR-K60N512\CAN

For instructions on how to import the demos into your workspace look at Where can I find Processor Expert examples and tutorials in CodeWarrior?

or  Where can I find Processor Expert examples and tutorials in Driver Suite?

Hi,

Which MCU are you using ?

You can find basic code examples in the Typical usage page of the component. To open it, use the command Help on component from the component pop-up menu and choose Component CAN_LDD Typical Usage in the Help view.

Regarding the read time operation system - no, it's not necessary, you can use the component without it in a bare-board projects.
