NUCLEO F401RE LOAD FIRMWARE CODE

Try to use these two functions to write code in your main function so that whenever the pushbutton is pressed, a “hello world” message will be transmitted through UART.

For the timeout, you can pick any value you want.

Pass this handle in to HAL_UART_Transmit.

The function takes the address of a UART handle, a pointer to the data buffer, the size of the data buffer, and a timeout.ĬubeMX named the handle husart and filled out its attributes in usart.c. Locate the UART Generic chapter and find the function for transmitting for UART in blocking mode, HAL_UART_Transmit.Scroll down to the list of functions, and find the description for HAL_GPIO_ReadPin which takes the port and pin of interest and returns its state.

Open the STM32F3 HAL datasheet that you downloaded and find the GPIO Generic Driver chapter.It also encapsulates a lot of the lower layer hardware details that we might otherwise have to worry about. STM’s HAL layer allows us to use the same functions regardless of the particular STM chip we are using, minimizing the number of changes we would have to make if we changed chips. We need a function that will allow us to read the pushbutton state and a function to send our message over UART. We will fill the while loop with code that will send “hello world” through UART whenever we push the blue USER pushbutton. *Initialize all configured peripherals */ * Reset of all peripherals, Initializes the Flash interface and the Systick. Navigate to the main.c file and scroll down to the main() function.ĬubeMX automatically wrote in our initializations for us and an infinite while loop that currently does nothing.

We’ll need to configure the same settings on the PC side. Our UART is configured with a baud of 115200, 8 bits per word with 1 stop bit, no parity, and some other features. Remember this for later.

To view our UART configuration, open the usart.c file and look for the MX_USART1_UART_Init function.

HAL_GPIO_Init(B1_GPIO_Port, &GPIO_InitStruct) GPIO_InitStruct.Mode = GPIO_MODE_EVT_RISING You’ll also see our UART TX and RX pins and LED 2. You’ll see a configuration for the USER pushbutton pin which is labeled B1 on the development board, but this is NOT port B, pin 1 on the chip.

Open the newly generated TrueSTUDIO project.ĬubeMX has generated a very simple project with some basic settings for you.

If so, click Yes to download it and wait for it to finish.

You may get a popup explaining you need a firmware package.

Hit Open Project at the popup prompt and your project should open up in TrueSTUDIO.

In the Code Generator tab, select Generate peripheral initialization as a pair of ‘.c/.h’ files per IP.

Give your project a name, pick a Project Location for your project, and select TrueSTUDIO from the Toolchain/IDE dropdown menu. By default, port A pin 10 is RX and port A pin 9 is TX. You’ll see that the graphic of the chip in the center will change and two pins on the right will change color to green (gray means that the pin is not configured to anything).

We are going to use USART1, so click on the + to the left of the name to open it up, and set it to Asynchronous Mode.

You should see a nice graphical interface appear, which we will use to set up our pins.

Finally, select the board that pertains to your model from the Boards List, and hit OK.

Open the MCU series dropdown and select STM32F1 if you have an F103RB, or select STM32F3 if you have the 303RE.

Select Nucleo64 from the Type of Board dropdown (yes, it’s a 32-bit microcontroller that is named Nucleo64).

In the Board Selector tab, look for the Nucleo board with the Vendor, Type of Board, and MCU Series dropdowns.

To generate the template project, open CubeMX and click New Project.

TrueSTUDIO (choose the free, stable release).

*Note the board type! You might have an -F103RB, or an -F303RE, or something else! If your development board is not labeled, the chip name is engraved on the chip in the center. STM32 Nucleo Development Board* and USB Mini B Cable
