ST Nucleo-F103RB Workshop
The NUCLEO-F103RB development board uses the STM32F103RBT6 as the target processor. This is the same processor used on "Blue Pill" boards.
This board far exceeds the Blue Pill boards and is a rock solid development board with on-board ST-Link loader / debugger.
To complete this workshop you will need to install the follow software packages:
- Install STM32CubeMX - https://www.st.com/en/development-tools/stm32cubemx.html
- Install Keil uVision5 - Keil MDK Keil Pack installer: https://www.keil.com/dd2/st/stm32g031j6mx

Board Features
Processor: STM32F103RBT6 128KB Flash 20KB SRAM 72MHz clock Single-cycle multiplication and hardware division 2.0 to 3.6 V application supply and I/Os
Hardware
- Green LED, LD2, connected to PA5, illuminates when driven high
- Blue PushButton, B1, connects to PC13, grounding the signal when pressed
- 32,768Hz crystal oscillator, LSE, used for Real Time Clock (RTC)
- 8MHz HSE, is provided by the 8MHz crystal oscillator from the attached ST-Link, into PD0
- UART2 connects the target processor to the ST-Link, providing a USB COM port connection on the host computer. Uses PA2 for TX, and PA3 for RX.
- ST-Link connects to TCK (PA14), TMS (PA13)

Getting Started
1 Open STM32CubeMX 2 Create New Project using "Start My project from ST Board" selector button 3 In the "Commercial Part Number" box, enter NUCLEO-F103RB 4 The board will display in the lower right part of the screen. Select the board. 5 Click on Start Project in upper right corner of window 6 A dialog will be displayed, asking "Initialize all peripherals with their default Mode ?" Select Yes 7 Using the Clock Configuration tab, a 64MHz SYSCLK is configured by default. This can be adjusted to 72MHz if desired. 8 Using the Project Manager tab, give the project a name. Something like "Blinky" will work well. 9 Within this same tab, select MDK-ARM for "Toolchain/IDE". This instructs the Keil uVision application to be used. 10 Select GENERATE CODE button in upper right corner. (You may get a dialog box indicating you are missing some dependencies. Select "Yes" to download them now.) 11 Select Open Project when prompted. (Keil may need to run it's package installer if it doesn't have support for the board. This will take some time. Don't click anything!) 12 Within Keil IDE, before we make any changes / additions to the code, let's make sure it builds. Click on Project -> Build Target You can use the short-cut icon, available in the tool-bar, to Build(F7) 13 Within the project view, open the project, and then the Application/User/Core folder and then double click main.c 14 The LED GPIO should already have initialization code within MX_GPIO_Init(). Find the infinite loop inside the main() function, and add the following two highlighted lines of code: /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); HAL_Delay(500); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } NOTE: Be sure to always place your code between the USER CODE BEGIN and USER CODE END comments This will protect your code from being removed should you make changes using the STM32CubeMX again. 14 Click Build (F7) 15 Click Download (F8) 16 At this point the board should now contain your code. Press the reset button to watch it run.
