Hi Segio,
Put your ASN.1 definition in a .asn file and run it through the ASN
compiler.
i.e. erlc MyDefs.asn
This will generate encoder and decoder logic in Erlang.
To decode a BER encoded record of MyType:
asn1rt:decode('MyDefs','MyType',BerEncRecord).
Please not that the ASN compiler does not (at least did not prior to
R8) support all ASN.1 constructs.
Please let me know if you run into any problems.
