Download the Bootloader BinaryĪs mentioned earlier, this repository consists of different binary files for different types of STM32 Boards.

Once this is done, you can connect the USB to Serial Converter to the PC and check for the COM Port. The first step is to connect the STM32 Blue Pill board to the USB to Serial Adapter as shown in the image above. To make things easier, the repo consists of downloadable binary files of the bootloaders (I will explain more about this in later sections). The source code available in GitHub at this link. Thanks to the contributions of LeafLabs (Maple Bootloader) and rogerclarkmelbourne, a repo of bootloaders is available for a series of boards. In order to upload the program via the USB Port on the Blue Pill, you need to have a USB Bootloader installed on the MCU. The following is the reference image for the connections. The connections between the STM32 Blue Pill and USB to Serial converter are similar to what I described in the Getting Started Guide.

USB to Serial Converter (like FTDI Programmer).

As an added benefit, you don’t have to fiddle with BOOT pins as you can leave it in the Operating Mode. The STM32F103C8T6 USB Bootloader provides such solution, where you can simply plug-in the Blue Pill to your PC via the USB Port and upload the program. It would be simpler if we can just make use of the on-board microUSB port on the Blue Pill board to upload the program. It is not that a difficult process to upload the program using the FTDI Adapter, but every time you want to upload a program, you have switch to the Programming Mode and for normal operation, you have to switch back to Operating Mode (toggling the BOOT0 pins between HIGH and LOW).

If you remember in the “ Getting Started with STM32F103C8T6” tutorial, I have shown you how to upload the program to a Generic STM32F103C8T6 board using an external USB to Serial Adapter. The same cannot be said for the STM32F103C8T6 Blue Pill Board.

It is that simple (provided you have the right drivers and selected the right USB Port). Just plug-in the Arduino to your PC and upload the program using Arduino IDE.

One thing that makes the Arduino UNO (or any Arduino board for that matter) special is its ease of programming.

Programming STM32F103C8T6 from USB Port.
