hello lalit…
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..
hey even m facing the same problem…….
i hv some basic difficulties lyk…..how cn set the baud rate of finger print module…..
what command sould i send to initialize finger print module…..
i even tried to interface it direct to pc using RS232 cable with its defaul baud rate but it is not responding…!!!
is there any command tht will confirm tht my finger print module is working fine….??
it would be great if i get some help related to this issue…..reply me plzzz
