If you don’t have Arduino IDE, you can download and install it from this link. Steps for the same are as below: Step 1: Install Arduino IDE Now, to program STM32F103C8 with Arduino IDE, first, we have to install the STM32 board in Arduino IDE. Installing Blue Pill STM32 board in Arduino IDE No need for hectic circuitry every time! The circuit for FTDI and Blue Pill is as shown below:Īfter successfully flashing bootloader, make sure you switch your STM32 again to operating mode. After flashing this bootloader, we can program the STM32 Blue Pill board directly through the USB port. We will require an FTDI programmer to flash Maple Bootloader into STM32F103C8 Development Board. We will need the materials mentioned below: So let’s get started! Materials Requiredīefore starting with steps to program Blue Pill STM32, I will enlist the material required. We can use this experimental bootloader to program Blue Pill STM32 with Arduino IDE. Fortunately, there exists an experimental bootloader by LeafLabs developed for MapleMini boards. To program Blue Pill STM32 directly from USB, we will flash Arduino Bootloader in it. So, we can not program a new STM32F103C8 development board through Arduino IDE. Unfortunately, the STM32F103C8 development board doesn’t come with an inbuilt Arduino bootloader.

Also, we need a serial programmer all the time when we have to program the Blue Pill. Programming a Blue pill through an external programmer is a very hectic task. Hence Blue Pill is also considered as an alternative to Arduino.Īs we mentioned earlier, there are two ways of programming Blue Pill.

There are some more noticeable differences where Blue Pill leads the Arduino. Also, it has 16 bit ADC while Arduino has a 10 bit ADC. STM32F103C8 (Blue Pill) has a higher number of pins as compared to Arduino Nano and Arduino UNO. 6 Program Blue Pill STM32 directly with USB port.5 Installing Blue Pill STM32 board in Arduino IDE.

4.6 Step 6: Change STM32 mode to operating mode.

4.5 Step 5: Bootloader will be uploaded to STM 32.

4.3 Step 3: Select your device in the target list.

4.2 Step 2: Connect the programmer to Laptop/PC and launch the software.
