• ST-Link v2 https://www.youtube.com/watch?v=KgR3uM21y7o
• Windows: you will need ST-Link v2 Driver https://my.st.com/content/my_st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link004.html#get-software

Connections

ATTENTION: DOUBLE-CHECK YOUR ST-LINK ADAPTER's PINOUT!

STM32 Blue Pill	ST-LINK V2
3V3 [Red]	3.3V (Pin 8)
IO [Orange]	SWDIO (Pin 2)
CLK [Brown]	SWDCLK (Pin 6)
GND [Black]	GND (Pin 4)

Board Infos

http://wiki.stm32duino.com/index.php?title=Main_Page http://wiki.stm32duino.com/index.php?title=Main_Page

Connect Board for serial upload

USB2Serial-Converter (FT232RL) --> STM32 (3v3-Mode!)

• GND --> GND

• 3V3 --> 3V3 (neighbor of GND) to power the board via converter

• TX --> A10

• RX --> A9

• Power STM32 via microUSB

• Connect USB2Serial-Converter to PC

Arduino BoardManager

• new URL http://http://dan.drown.org/stm32duino/package_STM32duino_index.json
• install STM32F1xx Board

Sketch

void setup() {
  pinMode(PA6, OUTPUT);

}

void loop() {
  digitalWrite(PA6, HIGH);
  delay(1000);
  digitalWrite(PA6, LOW);
  delay(1000);
}

Add LED with resistor to Pin6 (A6) and GND.

Troubleshooting (Linux)

Upload not possible

• uninstall modemmanager
• try to use USB2 port on your PC, avoid USB-Hub or USB3-port
