Anybody who has worked with R305 finger print module in their projects???Please reply....I am done with its coding and its working fine initially but after its continuous requirement ,it becomes exhausted.I want to discuss its working issues .
 

Should not - mine works fine... Try resetting and see if it resumes working then maybe code error is there...
 

Thanks for the reply alokdaga
I dont think there is an error in code because if i use fingerprint module code only in uC then it works perfectly fine and when i use my whole project code involving fingerprint code then iw works for intial 3 or 4 scans including the enrolling and storing function,searching function but after that it exhausts the blue led continuously glows and it is unable to detect finger..
Just tell me one thing i am using polling method for UART instead of interrupt.Is it fine??
 

resetting the uC resumes the working? Pl confirm
 

yes after resetting uC finger print module resumes its working..
Could you please tell me how to save the finger impression stored in fpm memory into uC's eeprom??
 

no idea about that.... Seems program looping is getting affected... generate a simple loop and try for debugging... or post your code here
