Just4pLeisure 4:682d96ff6d79 3 trionic8.cpp - CAN Bus functions for Just4Trionic by Just4pLeisure
Just4pLeisure 4:682d96ff6d79 4 (c) 2011, 2012 by Sophie Dexter
Just4pLeisure 4:682d96ff6d79 5
Just4pLeisure 4:682d96ff6d79 6 This C++ module provides functions for reading and writing the FLASH chips and
Just4pLeisure 4:682d96ff6d79 7 SRAM in Trionic8 ECUs. (Writing the adaption data back to SRAM not done yet).
Just4pLeisure 4:682d96ff6d79 8
Just4pLeisure 4:682d96ff6d79 9 Some functions need an additional 'bootloader' program to be sent to the T8 ECU
Just4pLeisure 4:682d96ff6d79 10 before they can be used. These functions are: Identifying the T5 ECU type and
Just4pLeisure 4:682d96ff6d79 11 FLASH chips, dumping the FLASH chips, erasing the FLASH chips, writing to the
Just4pLeisure 4:682d96ff6d79 12 FLASH chips and calculating the FLASH chips' checksum.
