" Error - [1209:BEBA] device is not found"
Means that your board does not have HID bootloader or it couldn't be booted into bootloader.
Port has to disconnect, as the board needs to reset to enter bootloader.

Re: STM32F103C8 128K - USB unknow
(...) I just don't see the COM, because my computer doesn't recognize it for some reason. I don't understand why this is happening, as I have installed already the necessary drivers for it to recognize the port. (...) You don't see COM port as there is none. You need to flash sketch with USB COM po...

Re: Port greyed out on arduino ide
If USB CDC is not enabled in your sketch, you won't see COM port as there isn't one configured.
DFU is completely different thing.

Re: [New User] Access additional pins from Arduino IDE?
Just use their "names" PA1, PB4, etc.

Re: DFU bootloader has errors on new BlackPill F411
@hdleng
It's not that simple. In my case, I need to touch GND and reset board.
The problem with entering DFU is caused by floating RX1 pin (PA10). So if using finger touching GND it might be pulled to GND as PA10 is close to BOOT and RST buttons.

Re: Issue with I2C between 2 STM32F411 black pill
Billie34 There's no such thing as "I2C pins are often mapped to PB10 and PB11". Each MCU may have different pins used for "same" interface. Read MCU datasheet or board pinout to find which pins are used for which interface. Also, there is no WeActStudio STM32F411 MCU. STM32 MCUs...

Re: Documentation for basic functions?
pwmWrite() is a function from libMaple/Roger's core. It's pretty limited compared to official STM32 core.

Re: USB virtual com-port for Blue Pill
There is no COM port on STM. COM ports are on PC. You have USB CDC (using virtual COM port on PC) or UART (not a COM, it's a simple serial interface). If you enable USB CDC (generic Serial supersede U(S)ART) "Serial" will use USB and U(S)ARTs wall start with Serial1. https://github.com/stm...
