Help needed with a Code hopping encoder-decoder scheme | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

Dear members: I�m currently envolved in a project dealing with access to buildings using wireless commands. I�ve chossen the Microchip Code hopping Encoder-Decoder scheme to improve security. More specifically, the chips are HCS301 & HCS512 respectively. My problem arises when I try to "sincronize" both chips by the process called "learning" in the datasheets. I�m pretty sure the manufacturer key, the system serial number and the selection of the encryption procedure are correct, but I�m not able to get a successful learning secuence. I�ve found a lot of decoder based in PICs, but the learning secuence described there is basically the same that I use. Even so, the information in the Microchips datasheets is not very detailed. �Has anyone of you any helping idea or experience? Thaks for your attention.
