Hello everyone,
I am working on a project where I am logging GPS data to SD card - later reading that data thought SD card reader, I have connected SD pins to SD Card reader and SPI pin from Arduino to SD Card, In between SD card and Microprocessor I am using LVC125A buffer gate, so whenever SD card reader is connected to any computer then this buffer gate will shut down doesn't provide any connection to SD card and the access to the SD Card will be only doing by SD Card Reader..
But, Here's the problem - whenever I connect SD card reader to my computer, computer is not detecting SD card - it only shows USB Mass Storage in Device Manager, But when I disconnect power to the system and connects system by shutting down output from LVC125A, then it's showing SD card in my computer..
I have researched on the internet about this issue and found I need to recycle power to SD card when every I connect to a computer.
is there any way to over come this problem.?
