does any body wrote a CAN protocol for this controller?
i need a help:
i have a protocol which communicate between 3 controllers: MAIN, GPS &
LASER.
the protocol works fine with MAIN & GPS.
the problem is with the Laser. in the protocol there is handshaking
between the MAIN & GPS/LASER.
for example: the main sends message with ID 50, and the other 2 should
answer him with mesaage ID 51.
in first time this occurs in the LASER, it works fine. the second time
the MAIN sends a message with ID 50, the LASER don't recive it (but
the GPS yes).
what can be the problem & how to solve it?
