Posted on February 12, 2013 at 18:27Hi you there!
Got stuck while programming a USB vendor specific device on STM32F4 MCU. The device is intended to be self-powered with custom usb driver.
During initial programming (core and device init. settings) I don't know what actually to do with the NZLSOHSK bit. What is it responsible for? If we turn to
http://www.beyondlogic.org/usbnutshell/usb4.shtml
, it says that non-zero length data is a DATA from the host and should be read by the application. So what to do with this bit? Should I keep it ''0'' or where am I wrong?
Thanks,
Peter.
