We will now insert some lines in the main.c file in order to flash the on-board LED. If you want to view the Device Configuration Tool again, just click the one with an. On the left is the Project Explorer pane where you can view all the project files. A really great feature!Īnother message window appears, this time asking you to open a perspective:Īnswering yes to this message will insert a pane on the right side which shows an outline of the code: If you click Yes, a template code will be generated with all the configurations already there. Here we can configure the initial state of PC13, its mode, pull-up/pull-down resistors and label.Īfter this, go to File -> Save (or CTRL+S). We can view more options for the PC13 pin by expanding System Core and then choosing GPIO. Since we're just flashing a LED, we make PC13 a GPIO_Output pin. A menu appears with all the possible functions of the pin. This means it's wired directly to pin PC13.Ĭlick on the PC13 pin on the Device Configuration Tool. In the Blue Pill you can see one of the LEDs with a label PC13. Our example project is an on-board LED flasher. This is a really neat feature of STM32Cube as it makes setting up your project faster and easier. Here you can configure the function of each of the pin of the STM32F103C8.

You should now be on the Device Configuration Tool window. Here I named it BluePill_Blinky:Ī pop-up window opens that asks you to open associated perspective. We type in our device, the STM32F103C8 and proceed: The Device Selection window then appears: Ticking the check box will skip this window on the next launch.įor first time users, choose 'Start new STM32 project'. Open STM32Cube then select location for your workspace. To start, download and install STM32Cube. That will be for a separate tutorial as we will be using STM32's own development platform, the STM32Cube. You can program the Blue Pill using the Arduino IDE, just like how you can program the ESP8266 and ESP32 breakout boards. It also has two on-board LEDs, BOOT jumpers, SWD connector and reset button. It can draw power from the microUSB port or the 3.3 V pins. The Blue Pill is designed to be similar to the Arduino Nano with 32 of the 37 I/O ports readily accessible.
