Arduino for STM32

Yeeeeeeeessssssssssss!!!!!!!!!!! Works perfectly! You are the brain!!!! Thanks very much! The last post that you wrote is the only thing that I made (RCC_OscInitStruct.HSEState = RCC_HSE_ON;). And I have to mention that the serial port for the Nucleo F401RE on Arduino is the Serial2. Now everything ...

I added the 8MHz crystal and it's capacitors triyng to solve the problem, but this didn't help. I think that the problem is the clock configuration, becouse even if I use the clock from the st-link(default source clock), the results are the same. I will try to do that you recomended and post the ...

const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int analogOutPin = PA5; // Analog output pin that the LED is attached to

int sensorValue = 0; // value read from the pot
int outputValue = 0; // value output to the PWM (analog out)

void setup ...

Thanks.
But if I set "Nucleo-64" and not "Generic STM32F4 series", then select "Nucleo F401RE", nothing works, the response of Arduino is ok, but the board didn't work.

Hi,
Did You solved the problem?
I have the same problem here, my Nucleo F401RE works perfectly on STM32 Cube IDE, but in Arduino, all the responses from IDE are ok, but the programs not run, even if I click on the reset button. However, if I select in the boards manager, the "Core Board F401RCT6 ...
