I aspire to make a small audio recorder. I need to decide how and on what it will record on, and how I will retrieve the files. I was originally considering having it record to microSD. Initial obstacles I found were speed limitations from using SPI, and the FAT32 drivers I was looking into will only access up to 4GB. FAT Driver I am reading up on. *http://www.embedded-code.com/source-code/memory/secure-digital-mmc-memory-= cards/secure-digital-mmc-memory-card-fat16-fat32-driver * Alternatively I was considering having the recorder write to flash memory and then retrieving the files via USB interface. I know next to nothing about attempting this method. Immediate obstacles for me would be figuring out the whole USB thing, and finding/writing FAT32 drivers for use with the flash memory (or do I?). USB stuff I have found. *http://www.signal11.us/oss/m-stack * I would appreciate any thoughts or input, suggestions, sources to read, what to consider, etc... What questions should I be asking myself? Note: I would like to be able to record stereo 48kHz/24-bit but I will settle on mono 44.1kHz/16-bit. -- James Burkart --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
