USBD_MSC example on nRF52833

[Yano]

Hi,

we are using an nRF52833 for an application where we have a sensors, a USB interface and an SD memory device.

We would like to write and read back sensor values to/from the SD memory.

Can we do this with the nRF52833 using 4 wires interface (writing data rate is slow 12KB a second into files)?

We would also like to connect a PC to the device through USB to read back the data (hopefully a bit faster).

The USBD_MSC example looks like a good starting point but is designed for QSPI on the nRF52840

I assume the nRF52833 doesn't support QSPI?

Could the example application be modified to work with the nRF52833 and a 4 pin interface?

If so do you have any other pointers on how best to port it?

Thanks

Hello,

Looking at the example documentation it seems like the USB MSC already include an option to enabled SD storage over SPI: USB MSC Example.

QSPI is not available on the nRF52833, but you don't have to select it in your project.

Best regards,
