Multiple CAN controllers and the CS Pin

[Jay Dee]

Hi guys,
When setting up the CAN component, an output is specified for the CS (chip select) pin.
Am I correct in assuming that this pin is automatically activated by the CAN macros, So I dont need to set the CS output before each CAN macro?

However, if I try to jump between two CAN controllers (hardware) using a single CAN component (software), I'll run into trouble as I cant select different CS pins.
Is the best step to just select the Extended CAN component and use this for the second CAN Chip.

P.S.
CAN VNET working a treat.
Regards,
John.

Hi John,

Yes you should be able to use the CAN and CAN2 components together using different chip select pins. It should also be possible to add more then one CAN component to a program so I will look into why this is not currently allowed.

Hello,

The attached component should allow you to add more then one CAN component to your program. I have checked that compilation is ok but not tested on hardware.

Simply copy the attached file into your "Flowcode v5/Components/" folder before starting Flowcode.

Let me know how you get on.

Thanks Ben, will test in the next couple of days and feedback.
