we have bought some MCP2515 PICtail Demo Boards to evaluate them and
then to develop a CAN interface system with the PIC16F676/677 for
our purpose on the same basis.
Now the problem:
We have downloaded the firmware - provided in the MCP2515 PICtail
Demo Board folder - from the original MicrChip website 00023R2.c
dated 2007 and other gadgets files.
Then we have compiled the supplied firmware with the MPLAB-X modern
XC8 compiler in free mode and then programmed into the Demo Board.
The Demo Board is not running - all LEDs are ON and not blinking
as in the normal state to indicate CAN activities.
When we program the supplied original HEX-file from MicrChip.com Site,
the Demo Board is running well.
Has anybody the same board - and if so - the suppied source files
was running without code changes???
If so - what must we do to get it to run - maybe a other compiler
or what else changes in the source?
What we have see too - the hex file is a other revision - 2005
and the source is from 2007.
Maybe here is a mistake by MicroChip
