SD fast read
Posted: 27 Oct 2014 20:17
I'm trying to read an sd card at very high speed for an audio player. My HW is based on Mikomedia for PIC24. The .WAV file is on an SD card. The idea is to use the library FAT32 for file system management and then write an handmade multisector read with DMA transfer on SPI from SD to PIC24EP512 and then to DAC. How can I retrieve the sector address of an opened file in order to exploit the CMD18 for multisector reading?
Thank you in advance
