Hi, I´ve been looking into the forum and online and I´m still not sure about the following question. Maybe it is absolutely obvious but I need to be sure. Can I interface an SDcard with a computer as a mass storage device WHILE accessing the file system with the MCU?? I have to poll for new files copied from a PC into the sdcard and send them via WiFi but the PC must always see the mass storage device while I´m reading and sending the files. Thanks!
