  • I was… But it has really been a huge pain in the *ss… I can give you some sort of base code using pic 16F788/877A-18F4550/2550. Those are the ones I’ve tried and the module answered just great. The matter is: I wasn’t able to process the string returned from the device, despite of knowing the answer string is perfect, I can’t go beyond a mirror of the answer, but I haven’t spent much more time focused on solve this. If you make it work it’d be awesome hahaha Saludos desde México

  • Nuevamente: GRACIAS! Ya pude realizar varias funciones, sólo me estoy familiarizando, pero vamos de maravilla :D Excelente ilustración. En efecto, venía en el datasheet pero no le había tomado sentido, puesto que nunca manejé así la comunicación. Ojalá aún puedas auxiliarme con un par de dudas, pero definitivamente trajiste luz a mi proyecto haha Bendiciones desde México

  • Caray! Haberlo dicho antes colega! haha Soy de México. ¿Podría ponerme en contacto contigo directamente? Porque sí me sería de mucha ayuda, ya que estoy trabajando con un 18F2550, aunque en realidad no me preocupa mucho mientras sea más o menos de esa familia (18F). Medio entiendo lo que me comentas acerca del envío y sí noto una diferencia sustancial a lo que yo he manejado para enviarle comandos al dispositivo. Muchísimas gracias!

  • Could you bring us some C++ or CCS demo code?? Because I haven’t found any of it and I have had a really hard time trying to communicate with the device, even with the demo software, wich, in deed, does all of the functions about storage, templates, etc. But the functions that imply the fingerprint sensor itself (detect if the finger is pressed, enroll, identify or verify…) are really a pain for my brain, because hardly ever detects the finger. It almost every time goes “Timeout”. Thanks

  • Do you have any experience working the C3 along with microcontrollers? Because I have had a hard time sometimes even communicating with the computer through the MAX232 interface; at least there sometimes it does the functions, just gets lost. But with the microcontrollers I haven’t had success trying to use the commands (hex) on the datasheet statements.

  • In deed. You must apply an input voltage of 3.3-6V, but either you use a resistante arrangement before the Rx (of the Fingerprint Reader) so you have an 3.3V signal in that input. Otherwise you might experience bad communication issues. Also you must be VERY CAREFUL about the connections. Good luck!

No public wish lists :(
