Timer STM32 #error This code is designed to run on STM32F/L/H/G/WB/MP1 platform! Please check your Tools->Board setting
The Roger Clark's STM32 core you're using is not currently supported. I don't know in the future if I can add that core into the supported list.
You have to use this Arduino_Core_STM32.

Am I at the limit of UART transmission time?
At 115200 baud you can send 11520 characters per second. At 20 bytes per packet you can send 576 packets per second. That's 1,736µs per packet.
That's assuming zero wait between bytes. That's not ...

How to extract the binary from STM32 MCU
you can download the flash content using a ST-Link probe and STM32CubeProg tool. you can't flash it to just "any" arduino board; it must be the exact same chip or same family MCU, if the IOs ...

Connect SDRAM to STM32
As far as I know, you have to choose variant with FMC module (Flexible Memory Controller) with SDRAM support - that means you have to use 144pin version STM32F730Z8. The 100pin version does have FMC ...

Difference between (*(volatile unsigned int *) and (volatile unsigned int)?
Judging from the context, RCC_BASE seems to be a preprocessor macro
that expands to the base address of some peripheral called “RCC”, and
AHB1EN_R_OFFSET a similar macro for the offset of the AHB1EN_R ...

My Arduino don't show port but is working
The STM32F103C8 has a native USB interface. You will only ever see a CDC/ACM (USB UART emulation) interface if you actively run code that implements a CDC/ACM interface.

STM32 "black pill" won't enter DFU mode reliably

Tying A10 to GND successfully makes it enter DFU bootloader mode 100% of the time (though just not leaving PA10 floating is probably sufficient)

In the first line, RCC_AHB1EN_R is a pointer to location.
you got that from the casting.
