Hi to all,
So for the last couple of weeks I have been working with a 2 line lcd and an uno. I have a aftermarket ecu in my car and all is working well with is no issues there. i created a can cable and terminated it and setup the CAN read demo. After looking at the data structure I feel that I have a pretty good handle on the data structure and its format, I think/though, not sure though. lol I have some values showing on the screen and its working for 3 parameters that I want to display but when i try to add a 4th output into position/byte 0 it stop updating values and leaves the last messages/values on the screen, If if move this message or delete the parameter added to byte 0 is proceeds updating again.
I am not sure what seems to be causing this but maybe someone can give me a hand
using a sparkfun mcp2515 can shield. I have attached the .zip if anyone want to down load and take a look.
if this is confusing let me know and I will try to explain better if I can.
