These special functions and their respective pins are illustrated in the Blue Pill pin diagram shown above. I 2 C ports – two-wire communication via the IIC protocol

STM32F103C8T6 BLUE PILL SCHEMATIC SERIAL

Serial ports – receive and transmit data via the UART protocol Most pins have extra functionality as well: Pull-up and pull-down resistors can be enabled on each of the pins. Each pin has a current sink/source ability of 6mA. The Blue Pill has 37 GPIO pins spread across four ports – A and B (16 pins), C (3 pins) and D (2 pins).

Supplying 5V to the 5V pin as external supply. There are three ways of powering your Blue Pill development board: This board aims to bring the 32-bit ARM core microcontrollers to the hobbyist market with the Arduino style form factor.

Press F5 to continue debugging and enable plotting in the Live Variables window.The Blue Pill is a 32-bit Arduino compatible development board that features the STM32F103C8T6, a member of the STM32 family of ARM Cortex-M3 core microcontrollers.

Once a breakpoint hits, add g_Counter to the Live Variables window:

Set a breakpoint in loop() and start debugging.

Add a global variable called g_Counter and modify the loop() method to increase it:

Now we will show how to step through the code in a debugger and to view the contents of global variables while the target is running.Once it is created and loaded, open VisualGDB Project Properties and set the correct board type and also set the “Optimize” field to Debug (-g): Ensure you have both the board and the ST-Link connected via USB and select them on the Debug Method page of the wizard: Ensure you set the “Connect under reset” checkbox, as the default Blue Pill firmware disables the SWD pins and will not allow connecting a debugger in the regular mode.

The STM32 Blue Pill board is based on the STM32F1 device, so pick Generic STM32F1 series in the device selector:

The STM32 Arduino package organizes the supported targets in 2 levels: first you need to select the target family via the project wizard and then specify the exact board type via VisualGDB Project Properties.

Proceed with the default “Blinking LED” option:.

Start Visual Studio and open the VisualGDB Arduino Project Wizard:.

In order to do that, remove the ST-Link/Nucleo jumpers and use the signals shown below: The final wiring should look as shown below: Now we will proceed with creating a VisualGDB project for the board. The picture below shows the location of the signals required for SWD-based debugging: Although we can use a stand-alone ST-Link programmer, in this tutorial we will use the one embedded into a STM32 Nucleo board. The firmware that is pre-loaded into the Blue Pill board reconfigures the SWD pins as generic I/O pins, hence we will not be able to debug the board via SWD unless we also connect the reset pin and enable the “Connect under reset” setting in the software. In order to debug the Blue Pill board via SWD, we would need to connect the following signals to an ST-Link programmer: We will show the necessary wiring to program the FLASH memory using the ST-Link programmer from a separate STM32 Nucleo board and will then proceed with debugging the Blue Pill board with SWD.

The Blue Pill development board based on ST Microelectronics’ STM32F103C8T6 microcontroller that has an ARM Cortex-M3 core that runs at 72MHz max. STM32F103C8T6 Microcontroller board mainly known Blue Pill development STM32 board with USB connector that can be used for USB device peripheral that is inbuilt in this controller.

This tutorial shows how to create a basic project for the STM32 Blue Pill board with Visual Studio and VisualGDB. by microdigisoft Published JUpdated November 4, 2021.
