Hi,
Im trying to use CAN comms with the Arduino MEGA, BUT the CAN options in the properties list only allow for 20 or 8 MHz, the Mega is 16, is there another way of configuring this? Can you send me a fix to include 16 MHz or (even better) make it a user set-able value?
regards,
Chris

Re: Arduino MEGA CAN Coms
Hi Chris
The CAN property speed relates to the crystal/frequency of the MCP2515 CAN controller chip, not the processor. So I hope that is either 20MHz or 8MHz, let me know if not.
We had to go for a fixed list, rather than a variable parameter, as calculating the options for the phase bit lengths gets a bit too complicated.
Thanks
Leigh
