While the Arduino IDE is opened copy this URL link. The Arduino IDE doesn’t come with the STM32 package pre-installed, we will need to do it manually. The jumper caps are set to their correct positions, and now we are ready to start working on the computer side. I connected the FTDI USB TO TTL board with the STM32 board as per the connections diagram. A9 is the TX pin while A10 is the RX pin.
#Stm Flash Loader Demo Download serial
The serial port number1 is available on A9 and A10. The TX and RX pins of the FTDI USB to TTL converter board are connected with the A10 and A9 pins of the STM32. VCC of the FTDI board is connected with the 3.3V pin of the STM32 controller board. The GND pin of the FTDI board is connected with the GND pin of the STM32. Why we need to do this? If you want to know about it then read my article. Next, you will also need to change the position of the jumper cap on the STM32 controller board. Before you start connecting this FTDI board to the STM32, first change the position of this jumper cap, we do it to select 3.3 volts. I would appreciate your support in this way!įor flashing the STM32 bootloader we will need this FTDI USB TO TTL FT232RL board. I may make a commission if you buy the components through these links. Without any further delay, let’s get started!!! I will add links to all the related softwares and drivers as I continue to explain things. A HIGH signal will turn off the LED while the LOW signal will turn ON the LED. For the demonstration purposes I started with the LED blinking program. After flashing the bootloader then you will be able to program the STM32 using a USB cable just like the Arduino Uno, ESP32, and Nodemcu ESP8266 etc. Although it has this micro USB socket but you cannot use it to program the STM32 board unless you Flash a booatloader and this is what I am going to explain in this article. This STM32 Blue Pill Controller board is based on the ARM Cortex-m3 STM32F103CT6.
STM32 Bootloader, STM32F103C Programming using USB Cable– If you are just getting started with the STM32 or STM32F103C which is also known as Blue pill.
