Generate the code using STM32CubeMx for Keil uvision. In this tutorial, we will learn how to generate Nucleo board UART / USART initialization c code for Keil uvision using the STM32CubeMx. STM32F401RE Nucleo board have 64pin ARM Cortex M4 + FPU on board running on the maximum speed of 84MHz. PIN 5 of GPIOA is connected with user LED and PIN 13 of GPIOC is connected with Push Button. It has one ADC with multiple multiplexed channel. PIN PA0 has multiplexed with ADC1 Channel 0.

The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer. The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as direct access to mbed online resources.

Thank you! Nicely done video. Watching your video allowed me to solve an issue that I was having with an STM32 UART transfer.

Re: STM32 Nucleo Tutorial 4- UART printf Coding in Keil using STM32CubeMx... Thanks for simplifying this little problem/issue with STM32 CubeIDE !!! Thanks much!

[gizemates]

billions of thanks to you my friend!! I've used several methods for doing this. This is the easiest and less problematic way. Thank you!

Thanks, I got it working. It's important to use a 8 bit word size when configuring the project with STM32CubeMx (as every char is 8 bit) and use the same settings on TeraTerm. The #define for the function used at the ending doesn't seem to work on some versions of keil 5, but it can be replaced with the function itself and it will be ok.

Hello. I have issue woth programming of STM32F207 ZG (Nucleo 144) Board. I am trying to program it for UART4 configuration using STM Cube MX. Program runs fine but no Output at the Virtual COM port. I used PA0 & PA1 for UART4 TX & RX (GPIOA). Can you tell me where is exactly a Problem??

[lorenrus]

To use printf are you using an external Debugger kit? How can I see the virtual monitor? Thanks

[Yassin_Ro]

Great Video Bro😊
Can you tell me please how can I delete the received data from Rx_buffer (UART interrupt) in order to receive new data from Rx_buffer[0] ?

[PEEYUSHKP]

Can you create a video tutorial for PWM Generation. It will be very useful. It is very essential for motor control which we find it really difficult.

[PEEYUSHKP]

is there any tutorial document for all the peripherals function of HAL for Nucleo

[wuerike]

Hey guy, nice videos you have been doing!

I started work with STM32 these days and I need learn lots o things about it as faster as I can. There is some book or online course or some thing like this that I can use to learn?

I'm trying to develop an aplicattion with several STM32F401RE communicating with each other with Sub 1GHz Module (X-Nucleo-IDS01A5), can you make a video about it? I just need learn about its specifics commands and how to use them.

[salaryunis]

very nice and clear explanation, Thanks!

[tedjohn]

Thanks alot! it works fine for strings but it doesn't work for floating point numbers. Any suggestion? Thanks!

[abdulwaiz]

hi with polling printf command is working perfectly but how to use with interrupt .as in HAL_UART_Transmit_IT(&huart1, (uint8_t *)&ch, 1, 0xFFFF); show the error../Src/main.c(118): error: #140: too many arguments in function call
thanks

[yago]

Hi, the first part works but when i try to use printf don't. I´m using True studio is might be the reason ?

[pragatibelsare]

Thank you so much successfully run this it possible to run same program using free rtos

[fredy]

Hello thanks for the video. I have an error: #20: identifier "FILE" is undefined PUTCHAR_PROTOTYPE, I don´t know why if I put it exactly as the video. also the first line after the #ifdef is not highlight #define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
. could you help me ?

[siscomteam]

please help me on this, i need to read float values from a text file and save themin a vector and process them (apply my work), thanks in advance.
