I am implementing the CAN module of K60, As known, the CAN module has 16 message buffers which can be configured as receive buffer and transmit buffer.
Now I want to configure 8 message buffers as transmit buffer,and call them "hard-buffer". It means that I can use the 8 transmit message buffers to transmit my CAN messages.
When I begin to send my CAN messages, I need to judge which transmit message buffer is empty, but I don't know how to judge it.
My questions are that:
1:how to jude whether a transmit message buffer is empty;
2:Is it necessary to use the 8 transmit message buffers to transmit CAN messages simultaneously.
