Posted on January 13, 2015 at 13:09I have an application which use the USB in the Boot but close it when I move to the APP. On the APP I stay on the stop mode. I notice I have extra 0.5ma there. When I didn't active the USB at all in the Boot I get less 0.5ma on the stop mode.
I do as follow to close the USB
''
&sharpifdef USE_USB_OTG_HS
NVIC_DisableIRQ(OTG_HS_IRQn); // disable USB HS IRQ
&sharpelse
NVIC_DisableIRQ( OTG_FS_IRQn); // disable USB FS IRQ
&sharpendif
RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_OTG_FS, DISABLE) ; // Disable power to the USB
PWR_DeInit(); // close all power
''
Is there any more commande I can do to reduce the extra power, and where it come from?
Thanks
Bar.
