Hello there
sorry if this another post of the same question.
I have an assignment to produce an asn.1 file that will contain one header, 0 or many details and 1 footer records.
All what I have is a table that specifies the tag name (like TE.T8 or TE0.TA3.TA2.T9F24 ), field name ( a descriptive name of the field), and the format (B,B2,B1..3 and other formats). I have no problem with the formats defined and I know the header fields and the details fields (repetitive) and the footer fields. I also know how to get the value of each field required.
I also have a sample binary file and a sample gdr file which shows the tags and the hexadecimal values as asccii values and a tool to convert these files from binary to gdr or from gdr to binary.
My problem is that I still dont know how to start this task. It is difficult to get more information about this task as it is an external interface with no enough support from the other party.
My current understanding is that I should use the table to write a formal asn.1 specification and then use a compiler to produce an encoder then use it to write the file. Is this correct and is this the only possible approach.
Any help is much appreciated
