This is the symbolic and commented source code for the DSM E931
and E932 ECU. To assemble "standard_E932_E931_source.asm",
download the telemark assembler TASM from http://home.comcast.net/~tasm/ to the same directory and execute asm.bat from the DOS prompt.
The assembler will produce two files: standard_E932_E931_source.lst
is a line by line listing of the assembly with addresses while standard_E932_E931_source.obj is the 32KB binary image to burn
on EPROM. Default setting produces the E931 standard binary image
Required file, not provided (from http://home.comcast.net/~tasm/): TASM.EXE, Version 3.2
Contents: standard_E932_E931_source.asm
Assembly source file for the E931/E932. See notes at the beginning of that file for more details. Default setting produces the standard E931 EPROM image.
asm.bat
Batch file to assemble standard_E932_E931_source.asm
standard_E931.bin
Binary file read from an actual E931 EPROM. Assembly of standard_E932_E931_source.asm using the "E931" setting should produce an identical binary.
standard_E932.bin
Binary file read from an actual E932 EPROM. Assembly of standard_E932_E931_source.asm using the "E932" setting should produce an identical binary.
standard_E931.lst
Assembly listing file for the standard E931, usefull if you just want to edit an EPROM image without assembly..
standard_E932.lst
Assembly listing file for the standard E932, usefull if you just want to edit an EPROM image without assembly..
tasm6111.tab
TASM compatible opcodes for the E931/E932 ECUs. Works with the provided source files. Might be incomplete if you want to use something not already used by the standard code...
