Hi Mark,
Before the update code is working to but with some error, I will fix my dbc
file to add signal for all message.
I have two question :
1. do you know how to config the dbc file to "compile" data from 2 Btye not
contigu ?
Example : ID 00FDF040 8 0x85 0x85 0x81 0x6A 0x7A 0xD9 0x4C 0x2E // ID
message contain 5 Cells Voltage
Cell 1 : #Byte 0 (0x85) | #LowByte 5 (0x9) => 0x859 => 2137 * 0,0015 =
3,2055Volts
Cell 2 : #Byte 1 (0x85) | #HighByte 5 (0xD) => 0x85D
Cell 3 : #Byte 2 (0x81) | #LowByte 6 (0xC) => 0x81C
Cell 4 : #Byte 3 (0x6A) | #HighByte 7 (0x4) => 0x6A4
Cell 5 : #Byte 4 (0x7A) | #LowByte 8 (0xE) => 0x7AE
the last Byte is the ID of BMS Board (0x2?)
2. The next step do after dbc load, How I can use information the value to
map or link with Standard metric ?
Thank you
Olivier
