This is why I actually used the car_linevoltage and car_charging current variables and put the can_buffer bytes 0,1,2,3 in them to see what am I getting... and the result was zeros. While the 4 and 5 are getting the old value.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">It almost seems like the CAN bus registers are not written when I am reading them.

just getting its value from the same memory location as last time... although it should have been initialized. </div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">Do the can_soc variable need to be declared as "volatile"?</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;">What is "internal" GPS?

I don't know PCAN, but the CAN byte numbering normally begins at 0
on the left, so 0e in your example is can_databuffer[2] and 7d is
...[3].<br>
<br>
If you get 0AB2, that would be [6][5] = your initial code?<br>
<br>
Btw: we could solve variable name conflicts between vehicle modules
by introducing some namespace prefix (replacing "can_") like Mark
already did for the functions. I'd shorten that for vars to e.g.
"vrt_" for "vehicle renault twizy", accordingly "vtc_" for the Think
and so on. OK, Mark?<br>
