| Abstract: | In order to record different data from multichannel in a UAV(unmanned aerial vehicle) correctly,a recorder based on embedded technology is proposed.The S3C2440 based on ARM920T is a microprocessor.A NAND Flash connected with NAND controller of S3C2440 is used as a storage device.And 8 UART interfaces are extended by 2 SC16C554D chips.For handing the invalid block and error correcting problems about NAND Flash,YAFFS2(yet another flash file system,version2) is adopted,which makes that the data can be saved co... |
