Hello all,
I am working on a project where I need to implement USB mass storage device.
PC(host)---USB---Controller---SD card
My SD card is communicating with controller on SPI2. As this microcontroller doesn't have the library for SPI so I used library code from STM32F103VBH6(eval board). But after integrating the code with my application I never get the device configured.I am new to USB and don't know how to go with it.
My USB is running at 48MHz. and SPI at 400KHz.
D+ is permanently pulled high with 1.5k resistor.
Do I need to make any changes needs to be done in the code.
Please let me know where I am gone wrong.
Thanks in advance.
