I am going to use usb on nucleo-f412zq but there is no HSE on the board how can i setup clock configuration to use usb? Thanks.
Hi farshid najafloo,
You may use the HSE in bypass mode (but HSI cannot be used).
I advise you to have a look on this discussion: "USB hardware and PCB guidelines" application note.
Should be an 8 MHz signal for HSE provided by the ST-LINK.
