can2usbDLL

can2usbAVR interface to vb.net

contains the can2usb.DLL which is the interface DLL to the Arduino/CAN Shield + can2usbAVR code, as well as a little VB.net test project, that can be used to connect to a KLINE/CAN T4e and discover the access level.

Solution Contents

• can2usbDLL - DLL project used by can2usbTestApp and the T4e ECU Editor to interface to the AVR/Arudino
• can2usbTestApp - can2usb Tester App
• Setup - a Setup project for above

KLINE+CAN ECUs (earlier MY's)

• select 1000kbit CAN speed
• KLINE+CAN ECU's should be freely readable, used the "Download ECU" function, specifcy a folder and you should be able to get the interessting parts of the ECU downloaded

CAN ECU's (later MY's)

• select 500kbit CAN speed
• CAN ECU's are locked down and can not be read out without prior flashing to enable those memory functions, however datalogging and OBD should work.

Tests

• Burst 0x80 - tests the datalogger function, ECU will reply with burst data containing the variables. This should work on CAN+KLINE and CAN ECU's
• Memory Read 0x50 - reads first 32 byte of calibration. This should work on CAN+KLINE ECU and previously cracked CAN ECU's
• OBD Read - issues a Mode 0x22 (Enhanced Vehicle Data) call via CAN/OBD. This will not work on CAN+KLINE ECU's because they support OBD only via CAN. Should work fine on any CAN ECU (T6e as well)

Download ECU

Works on CAN+KLINE or cracked CAN ECU's. Will download bootloader, flash calibration (calrom), calibration live data (calram), ECU program, and DECRAM (Non volatile memory/settings)
