Posted on August 28, 2017 at 10:35Hi everyone,
I am a biginner in ST-controller programming. Last week I spent time hunting the internet for finding some solutions about how to make a NUCLEO L476RG work as USB HID device. So I launched the example en.stm32cubel4\STM32Cube_FW_L4_V1.8.0\Projects\STM32L476G_EVAL\Applications\USB_Device\HID_Standalone\SW4STM32\STM32L476G_EVAL_USBD-FS in my L476RG after connecting the wires of my B-Female USB dongle as follow:
- D+ to PA12 (CN10-12)
- D- to PA11(CN10-14)
- GND to CN10-20
- Red wire VBUS to PA9 (CN10-21)
Fortunatelly, I could not get my Controller working: Nothing happened! After reading the chapter about OTG FS in the reference manual of STM32L4 serie I found (page 1629) that 'To build a bus-powered device implementation in case of the B-device or peripheral-only configuration, an external regulator has to be added, that generates the VDD chip-supply
from VBUS.' Now I want to know how to build the montage shown on the schematic attached to this post. Could someone help me please? I have been just employed and I am in the testphase so you can imagine my stress at this moment. Please Help!
