For mobile embedded system applications, a swipe fingerprint capture and mosaicking system based on STM32 is designed and realized. STM32F103RD is used as main controller, the swipe fingerprint is captured from AES1711 by DMA through SPI interface, and then the fast algorithm is used to realize fingerprint mosaicking. Experimental results show that the system has fast speed, good ro- bustness, low power consumption and high cost--effectiveness, so it can be used in mobile embedded devices.
