Hello am working on STM32L476RG development Board i am trying to develop a smart watch as part of my masters academic project when trying to import the code from mbed complier the code is compiled but it is not being dumped may I know the reason for it

Maybe it's easier to implement the same logic of the application on the application skeleton generated by STM32CubeMX?

I guess you want to do further development ouside of the mbed environment using regular IDEs like Keil or so?

If he is using third party C++ Arduino libraries, those may need C language conversion. It may become even harder if dependencies are multiple...

Also, if he is using a graphic LCD/OLED library, he may do better if he will search for such a library written in C for AVR or PIC microcontrollers if there is no one written for HAL/LL STM32 as such a library is easier to adapt.

Yes, right. We need more information to judge what is easier to do.

If the code is ok and verified on an Arduino hardware, mbed should provide a functional firmware after compilation. Try to divide the application, checking the functionality of each device. Try to make something simple that sends a text on serial, then add the temperature sensor that sends the values on the serial. Then check the OLCD separately, then combine them.

Okie sir

Under Linux, I never was able to use the Nucleo as a disk, so I had to download the firmware and burn it with the st-flash application...

But this piece of code is not been accepted for arduino IDE and may In know how can a piece of code written for Arduino board be converted to STM32 board as i had setup the Arduino IDE as STM32Duino

sir can you please provide me with that st-flash application link

I am working on ubuntu platform my board is being detected but the program is not stored
