各位大大好:
我是位初學者,想用PIC18 Start kit製作一個data logger. 想用"USB Device - Mass Storage - SD Card reader"的範例來改. 目前是改了: 1. FS_CONFIG.h 使其有write 功能 2. linker檔使用"USB Device - Mass Storage - SD Card data logger"範例的"rm18f46j50_g.lkr". 3. main中include FSIO..h build all 可以過 問題: 執行initResults = FSInit(); 結果initResults=false. 使用debug去看 MDD_MediaInitialize()...ok, mediaInformation->validityFlags.bits.sectorSize...ok LoadMBR(dsk)中的 MDD_SectorRead( FO_MBR, dsk->buffer) != TRUE......error 請問: 1.該如何解決? 2.這demo board 有提供這樣的範例嗎? 請各位大大不吝賜教..謝謝!
