Posted on December 21, 2016 at 17:23So I want my device to go into standby mode to run on the lowest power mode possible. Unfortunately, when measuring the current it does not drop below 360�A and I have no clue why...This is my HSI setup:configure_...

Due to power saving I want to disable the USB stack on the fly.
For comparison: If I do not enable the USB stack at all (e.g. by not invoking MX_USB_DEVICE_Init()) everything is fine. If I do and decid...

so I am using an STM32F411 as an USB device. It's connected via VCOM to a PC. I am using HAL V2.4.1 from19-June-2
In general it works good, but when I quickly connect and disconnect the u...
Posted on December 23, 2016 at 15:43So the 330µA could be traced back to a resistor that should not be present at all.It's working now. Thank you!But can someone finally confirm if I need to set my I/Os to analog-in before entering standby or not b...
Posted on December 23, 2016 at 11:12I am measuring the 3,3 line directly before the ST controller. We did a complete strip down of the PCB and removed everything; even the external OSC. Most of the I/O lines now are of course not routed. So no I/O c...
Posted on December 22, 2016 at 13:48oh man; it worked on the F411 Discovery board but not on my PCB. I guess I need to double check what draws the additional power in my design :\
