Fingerprint reader (UART) SN-FPR-UART

[Marvin_G]

Hello guys,first of all i don't know if i'm in the right category to post this topic but anyway, i wanted to ask about this fingerprint reader (UART) SN-FPR-UART. My project involved ARM processor TS-7390 and i wanted to connect this processor with this fingerprint throuh UART port. Is it possible? That's the first question. Second is my ARM processor is using Linux debian platform,is it possible to connect it through UART port to the fingerprint reader? Third question is if it can be connected through UART port then how do we control the fingerprint board? such as sending command to it from the ARM processor. Please help me,i need answers a.s.a.p. Thanks guys.

p/s: I hope someone who already had experience about this device can help me through this.

yes its possible.

Second is my ARM processor is using Linux debian platform,is it possible to connect it through UART port to the fingerprint reader?
yes, its possible. its easier compared to windows.

how do we control the fingerprint board?
The commands are in the datasheet. To control it in linux, you will need a usb to uart cable. Plug it into your computer or laptop. Do: ls /dev. You should see your uart to usb device. To read from the device use cat. To write to the device use echo.
You need to change the user dialout group:

sudo usermod -a -G tty yourUserName

sudo usermod -a -G dialout yourUserName

I never use ARM, but I use Fingerprint Reader with PIC. Ex. PIC Fingerprint Reader.

Thank you so much for your answer. I'm thinking using UC00A which is the usb-uart converter but it only have female usb port, does it have male usb port? so i can connect the fingerprint to my ARM board.

Plus, what do u mean by "you should see your uart to usb device"? do u hv the cmd for both read n write to d device?

How does the device really work? can you take the raw data and put it somewhere else?

I dont think so. You can use a male to female converter or wire.

plus, what do u mean by "you should see your uart to usb device"?
When you plug any device into your computer, you will see the device in the device manager right? In linux, type ls /dev, you should see a list of device connected. It is like your device manager in windows

Did you take a look at this: http://www.cytron.com.my/viewProduct.ph ... NvlbEFEQ7y

There are sample codes available.

Have you ever used this type of fingerprint? It does comparison but i don't know how. My method is first take raw data which i gained from this fingerprint and put it in database mysql then scan the same fingerprint and match it with those in database. Can i apply it on this device?

I will be using UC00B which have male usb port..is it ok? do i need driver for it? if yes, can i use the one in dis website http://www.ftdichip.com/FTDrivers.htm ?
