Setting up STM32

Install the STM32CubeProgrammer to upload to the STM32 micrcontroller.
Make sure the device is in BOOT mode when uploading with Arduino IDE / Platform IO (see pinout diagram)
The RESET on the STM32 micrcontroller needs to be pressed after switching between BOOT and RUN mode in order to read the change
1. Arduino IDE
Open Preferences > Additional Boards Manager URLs
Add a new line with the following url: https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json
Additional Boards Manager URLs
Open the Boards Manager from the Tools menu.
Search for 'STM32 MCU based boards' and click INSTALL
Arduino Boards Manager
Set the board to 'Generic STM32F4' 
Board part number to 'Generic F401RCT'
U(S)ART support to 'Disabled (no Serial support)'
USB support to 'CDC (generic 'Serial' supersede U(S)ART)'
USB speed to 'Low/Full Speed'
Upload method to 'STM32CubeProgrammer (DFU)'
The port does not need to be specified (having one specified should not cause any problems either).
Settings for uploading to STM32F401
Upload your program using the upload button in the Arduino IDE
Change to RUN mode when the upload process is successful
Press the RESET button on the STM32 microcontroller
The program should be running now
Press the RESET button when the device is not recognized by the computer
2. Visual Studio & Platform IO
Add STM32 boards (search for ST STM)
When starting a new project, select STM32F401RC with framework Arduino
Make sure the settings in the platform.ini file are as follows
[env:genericSTM32F401RC]
platform = ststm32
board = genericSTM32F401RC
framework = arduino
upload_protocol = dfu
monitor_speed = 115200
;only for monitoring serial data 
;the monitor port name can be read when the device is in RUN mode
;monitor_port = COM3
board_build.mcu = stm32f401rct6
board_build.f_cpu = 84000000L
board_build.core = ststm32
build_flags = 
	-D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
	-D USBCON
	-D USBD_VID=0x0483
	-D USBD_PID=0x0003
	-D USB_MANUFACTURER="Unknown"
	-D USB_PRODUCT="\"GENERIC_F401RCTX\""
	-D HAL_PCD_MODULE_ENABLED
lib_deps = askuric/Simple [email protected]^2.1.1
Upload your program using the upload button in Visual Studio
Change to RUN mode when the upload process is successful
Press the RESET button on the STM32 micrcontroller
The program should be running now
Press the RESET button when the device is not recognized by the computer
