I am trying to design a 4 door access controller. I have a complete working board of fingerprint scanner with DSP for fingerprint verification and authentication. I wish to design a microcontroller board which will communicate with this board to trigger the scanning process, store the data in PC and operate 4 relay circuits using the external wiegand relay output of the DSP. thanks in advance
