Abstract: In order to reduce the difficulty of secure digital memory card operation in microcontroller unit(MCU) system, a simple SD card driven method and interface circuit was introduced. This method is independent of partition table, so it sustains all kinds of SD card and partition formats, including FAT32, NTFS, exFAT format from 16 MByte to 32 GByte SD card. It can be appropriate for Masterslave control system using SD card. This method was used in LED display controller system. The application results indicate that the system achieves good effect.
