TC and Cal selector over CAN

Post by griff »

First Syvecs ECU so noob warning!
I was looking in SCal and the solution didn't jump out at me based on the options available so I figured I would ask the group here. 

So I have 2 cal switches (TC and Map) wired to an ECUMaster CanBoard in my steering wheel that sends the selector values on CAN2 as follows: 
Map:
ID=0x642 - offset=2 - 8bit where each position on the switch is a distinct hex value
TC:
ID=0x642 - offset=3 - 8bit where each position on the switch is a distinct hex value

How would you go about mapping those distinct hex values to their desired strategies or can it only be done by voltage input?

I guess I am just wanting to make sure selecting Traction Control and Map strategies via CAN inputs from the same bit is an option or if I need to come up with a different solution.
