exactly what i needed to know - thankyou ...
one odd thing i have noticed with can on the vipec tho ..
i setup channel 1 to send on id 500 as sequential
setup channel 2 with an id of 1000 as sequential
then sniff the canbus to see whats being send - i see about 18 to 20 id 1000 frames then one id 500 frame then another 18-20 id 1000 frames etc ... not what i expected at all ...
