i have interface r303a with avr microcontroller…
i am able to scan and and match images with that module but i am facing a serious problem with the function “search”.
as datasheet says that it is used to search in finger library.
Input Parameter: BufferID, StartPage (searching start address), PageNum?searching numbers?
as far as i know we need to provide
1.BufferID (which may be charbuffr1 or charbuffr2).
2.StartPage (In my case its 0x00).
3.PageNum (i m sending 5).
well this works for me initially then after 2 or 3 trails module stops repoding properly…
i need to reset my controller to get it working again. and the things goes like this again and again.
do you have any idea…!!! whts going wrong..
