The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The easiest way to program the board is to use OpenOCD. The Nucleo would be providing an 8 MHz clock on the HSE pin, it would also need to use HSE BYPASS mode. The ST Nucleo-F401RE board includes an on-board ST-LINK V2 programmer. BUG: Nucleo STM32 F401RE + FreeRTOS + STM32CubeMX 1.4. USART2 via STLink/USB or D0(RX)/D1(TX) and USART6 on PA12(RX)/PA11(TX) I am used to developing on Arduino and Espressif boards so I was expecting something like a serial monitor to debug the board but apparently things are not so simple on STM.11 (2x watchdog, 1 SysTick, 6x 16-bit, 2x 32-bit ) I have the right code in place, but unable to receive the output over USB. I have initialized the components in the right order (DMA before the ADC). I have been at this for weeks and cannot figure out why I cannot receive any data. The only issue is not being able to get that data onto my computer. I am also able to detect and measure the output of the sensor using the Logic Analyzer. Pins Legend NUCLEO-L476RG Specification NUCLEO-L476RG Manufacturer ST is a global semiconductor leader delivering intelligent and energy-efficient products and solutions that power the electronics at the heart of everyday life. On a hardware level (as I mentioned earlier) I know that the signals are being generated. Nucleo pinout The following figure is the pins legend. I tried varying the Baud Rates as well but no luck, not even garbage values. I confirmed that I am using the right port. 1 Create New Project using STM32CubeMX 2 Pinout Configuration 3 Clock Configuration 4 GPIO Configuration 5 Configure project and generate source code 6 Edit main.c to toggle the LED 7 Build the project 8 Debug the project 9 References 1 Create New Project using STM32CubeMX 5min Run STM32CubeMX tool. When I tried doing the same thing, using the same serial port reader, I don't see anything showing up in the console. When the person in the video opens a serial port reader (CoolTerm), he begins to see data showing up in the console without configuring anything (just pushes start). Then the output of the ADC is programmed to be sent over USB to the host computer. One of the interdependent signals triggers the internal ADC to read the sensor output via DMA (4th internal signal). Basically there is a master clock signal, and two other signals which are interdependent. In fact, I have replicated each and every setting to match what the video shows. This video tutorial that I have been following has the same configuration. Middleware -> USB_DEVICE -> Communication Device Class (Virtual Port Com).Connectivity -> USB_OTG_FS -> Device_Only.RCC -> HSE -> Crystal/Ceramic Resonator.I have the following configuration regarding connectivity: The NUCLEO-F401RE is a STM32 Nucleo development board with STM32F401RET6 MCU allows user to build their own prototypes for embedded applications. I confirmed (using a logic analyzer) that the code is generating the correct signals. I have programmed the board via CubeIDE and the program flashes onto the board without any problems. I generate 3 clock signals to drive the sensor. I have been trying to interface a sensor using an STM32F401RE Nucleo board but failing to receive sensor data from the board.
