LPC1768 ac as USB device in low speed

enpingado — Wed, 18 Aug 2021 16:03:27 GMT

I have an LPC1768 acting as a USB device to a host using USB 2.0.

It currently connects at the fullspeed (12mbps).

I want to configure the device/LPC1768 to use low speed(1.5 mbps).

I cannot find where this is configured if at all.

Is there a register to change the USB speed to use low speed?

thanks

Hello enpingado,

There isn't a register.

If the USB host connected to LPC1768 is low speed, it will automatically change to low speed.
