Hi,
What are the capabilities that the ARM_CAN_OjectGetCapabilities() returns?
Are they the capabilities for the object as programmed by ARM_CAN_ObjectConfigure()? Or are they capabilities representing what the hardware is capable of?
I am guessing that these refer to HW capabilities but I could almost guess the other way...
Thanks, Tony
Objects are a hardware entities, usually there are a few of controller types mostly they are an IP from Bosch which is source of CAN specification anyways.
So for example one controller has 32 objects which can be used for reception or transmission each depending on how they are configured. However, there are others which have only 1 object capable of transimission and 2 available for reception (with FIFOs).
So, to make your code portable you would go through capabilities of all objects and then assign what you need to specific objects.
BTW, why don't you take a look at existing examples in middleware for example one such can be found in c:\Keil\ARM\PACK\Keil\LPC4300_DFP\2.6.0\Boards\Keil\MCB4300\Middleware\CAN\CAN_Data\ where CAN_Data.c file contains example of CAN CMSIS driver usage.
Thanks!
I will take a look at the middleware example.
