vectrix FW

I've realised that the *.hex firmware files used to upgrade the vectrix contain readable data.
This is a small fraction of one *.hex file

BC 04 AE 47 00 00 BE 41 BE 47 BE 43 BE 4D BC E0 AE 29 00 2C AE 25 00 55
AE 25 00 AA AE 18 00 01 BC E0 AE 70 00 00 AE 71 00 00 BC E1 AE 10 1F D8
AE 12 01 DE AE 18 C5 FF AE 1A 1F 1F AE 1C D5 FD AE 1E 02 FF 7A 80 18 7E
7A 80 18 85 BC E0 AE 50 00 0F AE 51 00 0B AE 54 00 00 AE 52 00 00 AE 53
00 FF AE 59 00 AA BC E2 AE 03 30 02 4B 07 E2 00 00 7A AE 05 04 D7 AE 04
00 03 AE 03 24 82 4B 07 E1 00 00 83 AE 0A 00 00 AE 09 00 FF AE 01 FF 00
BC E2 AE 00 00 C0 BC E4 AE 01 80 F0 AE 00 03 00 AE 09 C0 FE AE 08 F6 4D

What kind of codification this is?

Re: vectrix FW

That is machine code.

each 2 letter value is a number in Hexadecimal, and is one byte of data.

Just about impossible to decipher.

I have a copy of some very old versions of firmware source code (.ASM files), PM if you would like a look.
The old firmware revisions are not compatible with the new versions though.

MaxForwardVelocity .set 5050 ;set max forward RPM
MaxEncCntsPerInt .set 183 ;=15ints*12.18cnts/int 183
MaxReverseVelocity .set 128 ;set max reverse RPM
ReverseGain .set 700
MinBusVoltage .set 97 ;Min allowed voltage on battery. Power is cut back to maintain this
