hi all
I've been messing about with CAN bus data on and off for a while now and have got my head around how it works so to speak.
I used a car speedo cluster to see if i can get it to do any thing and how got some functionality out of it (speedo is from a Vw polo 6c)
now i've logged a load of data from my own car (same model vw polo on the bus the speedo sits) and would like to see if i can transmit back to the speedo i have on the bench.
the log file i create using a teensy can be opened with savvycan (only once for some reason) i then want to export isolated Can Id frames to an SD card.
so i'm looking for the best way to go about reading data from a log file, apply it to a CAN Frame then transmit on the bus.
i've looked at the ReadcsvFile example that's part of the SdFat but it seems to do alot in the background and looks difficult to expand out to read larger files (than the small one it creates).
so i don't know if there is a simpler/easier way to go about reading data from a file and transmitting it on the can bus
