Just4pLeisure 0:e0b964252a05 7 Whilst I have written this program myself I could not have done it without
Just4pLeisure 0:e0b964252a05 8 a lot of help and the original ideas and programs written by:
Just4pLeisure 0:e0b964252a05 9 Dilemma - Author of the Trionic Suite software programs and general Guru
Just4pLeisure 0:e0b964252a05 10 http://trionic.mobixs.eu/ and http://www.ecuproject.com.
Just4pLeisure 0:e0b964252a05 11 General Failure - Author of the T5CANlib software and regular contributor at
Just4pLeisure 0:e0b964252a05 12 http://www.ecuproject.com.
Just4pLeisure 0:e0b964252a05 13 Tomi Liljemark - Lots of information and programs about the Saab CAN bus
Just4pLeisure 0:e0b964252a05 14 http://pikkupossu.1g.fi/tomi/projects/projects.html.
Just4pLeisure 0:e0b964252a05 15 Scott Howard - Author of the BDM software.
Just4pLeisure 1:d5452e398b76 16 Janis Silins - Valued contributor at http://www.ecuproject.com and creator of
Just4pLeisure 1:d5452e398b76 17 USBBDM. For sharing his BDM software (which also had a very useful method of
Just4pLeisure 1:d5452e398b76 18 entering commands)
Just4pLeisure 1:d5452e398b76 19 Plus inspiration and ideas from many others...

Just4pLeisure 4:682d96ff6d79 31 Version 1.4 (07/2013)
Just4pLeisure 4:682d96ff6d79 32
Just4pLeisure 4:682d96ff6d79 33 Changes since Verion 1.3
Just4pLeisure 4:682d96ff6d79 34 Progress indication shown as a percentage, slightly slower but more informative
Just4pLeisure 4:682d96ff6d79 35 T8 BDM Functionality
Just4pLeisure 4:682d96ff6d79 36
Just4pLeisure 4:682d96ff6d79 37 Changes since Verion 1.3
Just4pLeisure 4:682d96ff6d79 38 T7 CAN FLASH algorithm changed to only send 4 Bytes at a time
Just4pLeisure 4:682d96ff6d79 39 Slightly slower but more reliable especially with I-Bus connection

Just4pLeisure 3:92dae9083c83 43 Version 1.3 (06/2011) - Basic T7 CAN support and faster T5 CAN bootloader
Just4pLeisure 3:92dae9083c83 44
Just4pLeisure 4:682d96ff6d79 45 Changes since Verion 1.2
Just4pLeisure 3:92dae9083c83 46 New T7 CAN menu provides some very basic T7 CAN DUMP and FLASH functions
Just4pLeisure 3:92dae9083c83 47 T5 CAN uses Mybooty version 2 for 1 Mbps CAN speed
Just4pLeisure 3:92dae9083c83 48 Get MyBooty version 2.x from forum.ecuproject.com
Just4pLeisure 3:92dae9083c83 49 Does not work with version MyBooty 1.x

Just4pLeisure 2:bf3a2b29259a 53 Version 1.2 (12/2010) - Only a very small update
Just4pLeisure 2:bf3a2b29259a 54
Just4pLeisure 2:bf3a2b29259a 55 Fixed since Version 1.1:
Just4pLeisure 2:bf3a2b29259a 56 My method of detecting the FLASH type didn't work for T7 ECUs
Just4pLeisure 2:bf3a2b29259a 57 Now that that I have corrected this bug it is possible to
Just4pLeisure 2:bf3a2b29259a 58 FLASH Trionic 7 ECUs using the BDM connection
Just4pLeisure 2:bf3a2b29259a 59 See the 'get_flash_id' function in bdmtrionic.cpp
Just4pLeisure 2:bf3a2b29259a 60
Just4pLeisure 3:92dae9083c83 61 Changes since Verion 1.1
Just4pLeisure 2:bf3a2b29259a 62 I have removed everything to do with the BDM DS connection
Just4pLeisure 2:bf3a2b29259a 63 I have changed the mbed pin number for the BDM DSO connection
Just4pLeisure 2:bf3a2b29259a 64 Now all BDM connections are part of the same MBED 'port'
Just4pLeisure 2:bf3a2b29259a 65 Being part of one port makes it possible to change all
Just4pLeisure 2:bf3a2b29259a 66 connections simulataneously so speeding up BDM
Just4pLeisure 2:bf3a2b29259a 67 See 'interfaces.cpp' for details of how the mbed pins connect.
Just4pLeisure 2:bf3a2b29259a 68 Uglybug's wiring circuit has these connections (thanks Uglybug)

Just4pLeisure 1:d5452e398b76 72 Version 1.1 (09/2010) - Still very crude way of doing things
Just4pLeisure 1:d5452e398b76 73
Just4pLeisure 1:d5452e398b76 74 Additions since Version 1:
Just4pLeisure 1:d5452e398b76 75 The BDM interface is now working
Just4pLeisure 1:d5452e398b76 76 Based on Janis Silin's BDM software with modifications and additions
Just4pLeisure 1:d5452e398b76 77 Detect which type of FLASH chip is fitted to work out type of ECU
Just4pLeisure 1:d5452e398b76 78 Modifications to FLASH algorithms - I think my algorithms are
Just4pLeisure 1:d5452e398b76 79 closer to the datasheet methods. Still to do:
Just4pLeisure 1:d5452e398b76 80 Separate pulse counters for 28Fxxx erase
Just4pLeisure 1:d5452e398b76 81 DQ7 and DQ5 checking method for 29Fxxx FLASH
Just4pLeisure 1:d5452e398b76 82 Works for T5.5 ECUs with 28F010 and 29F010 chips
Just4pLeisure 1:d5452e398b76 83 Probably works with T5.2 ECUs (chip detection method)
Just4pLeisure 1:d5452e398b76 84 MAY work with T7 ECUs ('prep' method may need changes - I can't test T7)
Just4pLeisure 1:d5452e398b76 85 NOTE: Some of Janis' original BDM commands may not work, or at least
Just4pLeisure 1:d5452e398b76 86 not as originally intended
Just4pLeisure 1:d5452e398b76 87 Lawicell CAN232 interface partially working
Just4pLeisure 1:d5452e398b76 88 Only a few Lawicell message types to open/close, set speed and write
Just4pLeisure 1:d5452e398b76 89 Trionic5 CAN functions
Just4pLeisure 1:d5452e398b76 90 All-in-one 'D' and 'F' commands to DUMP and FLASH BIN files
Just4pLeisure 1:d5452e398b76 91 Lots of checking for errors, either works or says it failed
Just4pLeisure 1:d5452e398b76 92 No need to interpret the cryptic CAN messages anymore
Just4pLeisure 1:d5452e398b76 93 Should now work for T5.2 and T5.5 ECUs
Just4pLeisure 1:d5452e398b76 94 Detects FLASH chip type and works out which ECU is connected T5.2/5.5
Just4pLeisure 1:d5452e398b76 95

Just4pLeisure 1:d5452e398b76 98 Version 1 (04/2010)- The basic CAN functions are working
Just4pLeisure 0:e0b964252a05 99
Just4pLeisure 0:e0b964252a05 100 I have decided to 'release' this software somewhat prematurely because the FLASH
Just4pLeisure 0:e0b964252a05 101 chips in my spare ECU have 'died' and I don't know when I will be able to do
Just4pLeisure 0:e0b964252a05 102 carry on improving and 'polishing' it. This way others will be able to use and
Just4pLeisure 0:e0b964252a05 103 enhance it without having to wait for me.
Just4pLeisure 0:e0b964252a05 104
Just4pLeisure 0:e0b964252a05 105 For now, only option '5' Trionic ECU CAN interface is working. BDM and Lawicell
Just4pLeisure 0:e0b964252a05 106 CAN232 functions are dummies. The intention is to build a complete suite of CAN
Just4pLeisure 0:e0b964252a05 107 software for Trionic5, 7 and 8 ECU types as well as adding a BDM interface to
Just4pLeisure 0:e0b964252a05 108 make an 'all-in-one' USB programming tool.
Just4pLeisure 0:e0b964252a05 109
Just4pLeisure 0:e0b964252a05 110 To make this you will need an mbed system and the CAN circuit from this page:

Just4pLeisure 0:e0b964252a05 112
Just4pLeisure 0:e0b964252a05 113 Some ideas for the truly creative and adventurous of you is to make a gizmo that
Just4pLeisure 0:e0b964252a05 114 doesn't even need to be connected to a laptop or PC to use, maybe even a self-
