Hey Guys!
I'm working on a project that requires both an Atmel2560 and a connected computer to both have the capability to read/write to an SD card. Basically, the Atmel2560 is connected to the MicroSD on board the PCB through a Hex Converter. The board is designed to operate with connection (and power) to a USB-B port. The Atmel will be dumping data to the SD card continuously however from time to time we need the ability for the computer to explore the SD card and access the data. If that requires pausing the read / write from the Atmel - we can live with it.
I've been looking into solutions involving the LUFA code using an Atmega32U4 or possibly the VUB300. However, no clear solution is presenting itself.
Your help / suggestions are greatly appreciated! I'm happy to provide any additional details that are needed.
