Hi!
In my project, I need to export data to USB disk with the FatFs file system on lpc1788 platform. The real speed I tested was 400KB/s~450KB/s.
Official documents show that the USB speed can reach 12Mb/s(1.5MB/s).
The USB device controller on the LPC178x/177x enables full-speed (12 Mb/s) data
exchange with a USB host controller.
Therefore, my question is, what is the maximum speed that lpc1788 can export data to USB disk, and how can I improve the speed?
Hi, Geng,
I think the Flash erasing/programing dominate the usb disk speed rather than the USB transfer speed.
