![]() Then, go to Tools > Port and select the appropriate port through which your board is connected.Therefore go to Tools > Board and select Generic STM32F103C series.DemonstrationĬhoose the correct board and COM port before uploading your code to the board. This occurs inside the infinite loop function hence causing the onboard LED to toggle after each second. They are valid also for Windows XP, with small differences in the dialog windows. The following code sets PC13 to a high state for a second and then to a low state for a second. The following instructions are for Windows 7, Vista and 10. the loop function runs over and over again foreverĭigitalWrite(PC13, HIGH) // turn the LED on (HIGH is the voltage level)ĭigitalWrite(PC13, LOW) // turn the LED off by making the voltage LOW initialize digital pin PB1 as an output. the setup function runs once when you press reset or power the board for Maple mini 25th April 2015, where the LED is on PB1 This example code is in the public domain. Pin the on-board LED is connected to on your Arduino model, check Leonardo, it is attached to digital pin 13. Most Arduinos have an on-board LED you can control. Turns on an LED on for one second, then off for one second, repeatedly. Remember to change the LED pin configuration in code accordingly. For STM32 Blue Pill, the onboard LED is connected with PC13. The basic example sketch to toggle the onboard LED after every second will open up. Prerequisitesīefore we move ahead, let us list the hardware components and the software packages that will be required for this guide. ![]() Follow this step by step guide to successfully blink the onboard LED of your Blue Pill with Arduino IDE through the micro USB port. Therefore, in order to utilize the USB port of Blue Pill ad upload code just like with other microcntrollers like Arduino, ESP32 etc. Moreover, as seen in previous STM32 Blue Pill tutorials, in order to successfully upload code we had to move the BOOT jumper from 0 to 1 to enable the microcontroller to go into programming mode. If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit. If you are running a 32Bit Windows: run the SETUP32.EXE installer. If you are running a 64Bit Windows: run the SETUP64.EXE installer. Go to Tools > Serial Ports and if the FTDI drivers are not installed, you will not be able to select COM port in the Arduino IDE. Plug the FTDI module in one of your computer’s USB ports and open Arduino IDE. Often FTDI drivers will be automatically installed by your system when using Arduino. Therefore, we use USB-TTL converter to upload code as the board is not discoverable if connected through the USB port. Older Windows Driver Version and Instructions. In both situations you need to install or update the drivers. The STM32 Blue Pill comes with a micro USB port but it does not contain the Arduino ready boot loader. It is a step by step guide which will help you to install STM32 Bootloader and then program your Blue Pill through the micro USB port using Arduino IDE. In this tutorial, we will learn how to program STM32 Blue Pill through USB port by uploading Bootloader to the board.
