First you have to set baud rate of 57600 bps to communicate with r303 fingerprint module. Then you have to send command like Get Image, Generate char file from image, Generate template & store template from the microcontroller.
After giving any command from the controller the r303 module will acknowledge that command & you have to check confirmation code from that acknowledgement.
Read the the datasheet & try the code coming with cd of r303 fingerprint module.
Shailesh KuknaParticipantSFG Demo or Synochip Demo
These software are available in CD with this module or you can download from the internet.
Shailesh KuknaParticipantR305 has its own processor. You have to communicate with the processor by the command giving to it by microcontroller.
Shailesh KuknaParticipantTo communicate with fingerprint module r305 which has a default baud rate of 57600 bps.
Shailesh KuknaParticipantR303a is working with its own protocol.
You have to read datasheet for that carefully.
When communicate with 8051, the controller has to send a command packet to the R303a fingerprint module.
After receiving command from the controller, the module send acknowledge command to the controller.
VryPwd[] is a command sent by controller to the module.
First two bytes are header, next four are address, next one is for package identifier, next two are for package length, next one is for instruction code, next for are for password of module, and last two are checksum.
Again I say that read the datasheet carefully.
September 28, 2014 at 2:00 pm in reply to: I have some problem regarding RFID madule interfacing….. #12237Shailesh KuknaParticipantSee code of RFID based attendance system from this webside. It will helpful to you.
Shailesh KuknaParticipantYes I knew that AVR has 2 UART but it it is challengeable job for me & others also.
Shailesh KuknaParticipantWell I got the answer..
Both are optical fingerprint sensor.
Storage capacity of SM630 is more than R303.
SM630 has 64kb of flash memory that can store upto 768 templates whereas R303a can store upto 120 templets.
Also prise of SM630 is more than R303.
Shailesh KuknaParticipantThanks for reply…
I have found two fingerprint modules from internet Model No. SM630 & Model No. R303.
I want to know which module can be best suitable for interfacing with AT89S52?
